Swan Lake lives up to its name

Straw’s Bridge Nature Reserve in Derbyshire is known to the locals as Swan Lake, and with good reason. Although both a Canada goose and a mute swan appear on its signage, there’s no question which is the top bird…and it’s not the goose! When we were last here the star attraction was a pair of mandarin ducks. Sadly they were nowhere to be seen this time, but mute swans were out and about in large numbers.

Families were also out in force, many clutching loaves of sliced bread to share with their feathered friends. I’ve got mixed feelings about this. Bread is not appropriate food for waterfowl and is definitely not recommended for swans (although the local brown rat population loves it!) On the other hand, it’s great to see people getting up close and personal with swans, and introducing their children to these magnificent creatures.

There are around 6,000 breeding pairs of mute swans in the UK, and numbers rise to around 70,000 individuals in the winter when migrants arrive from the continent in search of better weather. They are impressive birds. With a wingspan of up to 2.4 metres (nearly 8 feet) and weighing in at almost 12 kilos (26 pounds) they are the largest of the UK’s wildfowl, a formidable presence on rivers, lakes and ponds all over the country. But they come with a health warning: as a kid I was often on the receiving end of the dire predictions about what they would do to me given half a chance: don’t get too close, worried adults would caution, that swan’ll break your arm in an instant.

Of course I know now that this was a gross exaggeration, and a terrible slur on a wonderful bird. Sometimes they’d hiss a bit if I got too close to a nest of chicks, but the swans I encountered never resorted to violence. For the most part they seemed like improbable, gentle giants and I was a little bit in awe of them. I am still, I guess, and look forward to revisiting Swan Lake in a few weeks time when some newly hatched cygnets should be on show.

Footnote on the quirky history of English swans (aka Swan Upping)

In medieval England swans were a highly prized menu item at banquets hosted by the nobility, and as such were a valued status symbol for those able to serve them up. Reflecting this cherished position, every mute swan in England was deemed to be the property of a major local landowner, each of whom gave the swans in their ownership a unique pattern of marks on the beak.

Beginning in the 12th century, an annual Swan-Upping exercise was carried out to manage the ownership of wild, free-flying birds. Adult mute swans and their new cygnets would be captured. The adults’ beaks would be examined for marks of ownership, and their cygnets given similar marks.  Any unmarked adult swans would be claimed by the Crown.

Of course the monarch, as chief amongst the nobles, had a particular interest in the management of mute swans. This interest is illustrated by the royal Christmas festivities of 1251, when King Henry III served up 125 birds (around 1 ton, or 1,000 kilos, of swan flesh) to his cronies. To ensure a steady and sufficient supply of this avian delicacy the Crown claimed ownership of mute swans on certain stretches of the River Thames and its surrounding tributaries.

By the 15th century the monarch was sharing ownership of swans on ‘his’ stretch of the Thames with the Vintners’ and Dyers’ Companies, two London-based medieval trade organisations. During the Swan Upping ceremony the Worshipful Company of Dyers would mark their swans with a nick on one side of the beak, with the Worshipful Company of Vintners marking theirs with a nick on each side. The swans belonging to the Crown were unmarked. 

Although swans are now protected by law and eating them is strictly forbidden, the quaint and archaic ritual of Swan Upping has been reinvented to help support the conservation of swans. This fascinating YouTube video, featuring Her Majesty the Queen’s very own official Swan Marker, explains more. You just couldn’t make it up!

Escape to the country

Last week, after three long, weary months, the government lifted its “Stay at Home” Covid instruction. We quickly decided to escape to the country for a few hours. The weather was unusually warm for the time of year and we expected to find the car parks at Carsington Water overflowing with ecstatic visitors making the most of their first day of freedom in 2021. As it happened numbers were modest, ensuring our visit was a good deal more tranquil than we’d feared.

Canada geese grazing next to the reservoir

Carsington Water is the ninth biggest reservoir in England. It was formally opened in 1992 after what can only be described as an eventful construction: in 1983 four workers tragically died, asphyxiated while working in a 16 foot (5 metre) surface drain, and a year later part of the dam wall collapsed. Nearly 30 years on, however, the reservoir has been seamlessly integrated into the Derbyshire landscape and is a popular centre for a range of recreational activities, including walking, cycling, fishing, sailing and canoeing. With a good proportion of Carsington Water designated as a nature reserve, it is also a favourite spot to watch birds.

Great tit

In our experience rarities are rare at Carsington! However this isn’t a problem for us: we are not twitchers and have never been motivated by the desire to “tick off” rarities. All birds, whether uncommon or not, are wonderful and worthy of attention. Even Canada geese!

Robin

Inevitably, Canada geese were liberally scattered throughout the reserve last week, some floating serenely on the water, others grazing greedily on the meadows adjoining the reservoir, and a few honking noisily as they flew overhead in search of pastures new. You can be sure of getting your fill of Canada geese on any visit to Carsington. Not to mention mallards, coot and black-headed gulls!

An unexpected nuthatch

Although Carsington Water is an obvious spot for watching water birds, on this occasion some of the best action was on and around one of the feeding stations. Great tits and robins were the most frequent visitors, and a nuthatch the most unexpected.

Primulas prove that spring has sprung

The woodland in which the feeding station is situated was dotted with primulas, evidence that spring has well and truly sprung. And mindful, no doubt, that Easter was fast approaching a rabbit put in a brief appearance, while at one point a vole scurried across our path, way too fast to be photographed. Again, nothing exceptional here, but all such welcome sights after thirteen weeks of lockdown.

One of Carsington Water’s very own Easter bunnies

We’re fortunate that Carsington Water is just a few miles from our home town, and now Covid restrictions are being relaxed we’ll be escaping to this part of the country regularly to sample once again the joys of birding on our local patch. After all, a man just cannot see too many Canada geese!

* * *

POSTSCRIPT, Tuesday 6 April, 2pm. Having written this post over the weekend, this morning we made a return trip to Carsington Water and were thrilled to spot no fewer than 16 swallows, newly returned from Africa, wheeling and whizzing over the water. It’s official then, spring really is here!

Where have all the sparrows gone?

Last Saturday, 20th March, was World Sparrow Day. Needless to say, no sparrows turned up in our garden to celebrate the occasion. When we moved in 35 years ago house sparrows were common here, squabbling noisily and boisterously on the bird table. Now, if we get half a dozen sightings over a 12 months period we class it as a good year for sparrows. Here, and throughout the UK, house sparrow numbers have been in serious decline for decades.

House sparrow

Growing up in West London half a century ago sparrows were the most familiar birds in our garden. Our name for them was spugs, or alternatively spadgers. They were very common, part of the wallpaper of our suburban lives, and we took them for granted. No one would have believed then that one day they would be “in trouble.”

The State of the UK’s Birds 2020 report published by the RSPB suggests that there were 5.3 million breeding pairs in the UK in 2018, making the house sparrow our third most common breeding bird behind the wren (11m) and the robin (7.3m), and marginally ahead of the woodpigeon (5.2m). It adds that “In the late 1960s there were 10 times more house sparrows than woodpigeons. We have lost around 10.7 million pairs of house sparrows in that time, a loss greater than for any other species, and gained 3.5 million pairs of woodpigeons.” No surprise, therefore, that the house sparrow is on the UK’s Red List for birds of conservation concern.

The latest figures offer a glimmer of hope: numbers are now thought to be stable or increasing in Scotland, Wales and Northern Ireland. However this is little consolation to those of us in England, where numbers continue to fall.

House sparrow

The cause of the rapid decline, particularly in urban and suburban environments, is unclear, although a lack of invertebrate prey for chicks – perhaps resulting from pollution or increased used of pesticides by gardeners – is believed to be a factor. Other proposed but as yet unproven reasons include reduced opportunities for nesting in the modern urban environment, and predation by domestic cats. Declines in rural house sparrow populations are thought to be linked to seasonal food shortages resulting from changes in agricultural practices, particularly the move to sowing cereal crops in the autumn.

* * *

Although the decline of house sparrows in the UK has been dramatic, the declaration of the first World Sparrow Day wasn’t a British initiative. Instead it was the brainchild of Nature Forever (NFS), an Indian non-governmental, non-profit organization which aims to “involve citizens from all walks of life, diverse backgrounds and different parts of the country and the world” in conservation projects. Nature Forever’s championing of the house sparrow is a good indication of the bird’s global reach.

Ted Anderson, Emeritus Professor of Biology at McKendree College in Illinois has argued that the house sparrow is the most widely distributed wild bird on Earth. It is believed to have originated in the Middle East, but having developed a close association with humans, it extended its range across Eurasia in tandem with the spread of agriculture. More recently Europeans have deliberately introduced the house sparrow to other parts of the globe, either as a pest control initiative or to remind them of home, and accidentally taken them to other locations as stowaways on their ships.

In happier times. House sparrow at Platypus Towers

It’s perhaps no surprise therefore that, in recent years, Mrs P and I have seen many more house sparrows on our visits to North America, Australia and New Zealand than we ever manage to spot in our own backyard. If numbers here continue to fall the time may well come when we have to go cap in hand to our former colonies and beg to have some of our sparrows back. Oh, the humiliation!

* * *

In folklore and literature sparrows have an enduring reputation for sexual promiscuity. Geoffrey Chaucer reflects this in the Canterbury Tales when he writes “As hot, he was, and lecherous as a sparrow . . .”  Two hundred years later, in 1604, William Shakespeare wrote in Measure for Measure that Sparrows must not build in his house eaves, because they are lecherous . . .”

Tree sparrow. Note the diagnostic brown crown and black cheek spot

Amazingly, modern science shows that these seemingly outrageous accusations are not entirely inaccurate. DNA analysis has shown that 15% of the chicks produced by a settled pair of house sparrows are in fact the offspring of a third party, proving once again that truth is stranger than fiction.

* * *

The house sparrow is not the only species of sparrow found on these shores. Although the so-called hedge sparrow, also known as a dunnock, isn’t really a sparrow at all (it belongs to the family birds called accentors), the tree sparrow really is a sparrow.

While house sparrows are regularly seen in both urban and rural settings, the tree sparrow is very much a bird of the countryside, particularly hedgerows and woodland edges. Their distribution tends to be localised, and they are much less plentiful than house sparrows: the latest population estimate is 245,000 breeding pairs. We have not and would not expect to see tree sparrows in our suburban garden, but there is a nature reserve within a few miles of Platypus Towers where we can often spot them.

Tree sparrow

It’s always a pleasure to see tree sparrows since they, like house sparrows, have suffered a calamitous decline in numbers (around 90%) since 1970, although in the last few years that fall has slowed and may have started to reverse. Again, changes in agricultural practice are the likely cause, and with no prospect of these being reversed the tree sparrow remains on the UK’s Red List for birds of conservation concern.

And finally, to conclude my little celebration of World Sparrow Day, I commend to you Dolly Parton singing “Little Sparrow.” The songs begins with these words

Little sparrow, little sparrow
Precious, fragile little thing
Little sparrow, little sparrow
Flies so high and feels no pain

Of course, the song isn’t really about sparrows at all. For Dolly, the sparrow is a simply a metaphor for gentle innocence, and anyway the North American sparrows about which she sings (Emberizidae) aren’t in the same family as Old Word sparrows (Passeridae). But whatever, that second line has always haunted me. In four words it captures perfectly the magic of birds both great and small, and encapsulates my feelings for them. Birds are precious and fragile, and even relatively common birds like the sparrow need our help if they are to continue to fly high and feel no pain.

Celebrating World Wetlands Day: return of the cranes

Yesterday was World Wetlands Day. Held on 2 February every year since 1997, the Day aims to celebrate and raise global awareness about the vital role of wetlands for people and our planet. To the casual observer wetlands may not seem vital at all, but instead an inconvenient and undesirable quagmire of mud, mosquitoes and misery. The truth, however, is very different.

Wetlands take many forms, including rivers, lakes, ponds, marshes, fens, swamps, mangroves, estuaries, floodplains and lagoons. Why are they considered vital? To put it at its most basic, wetlands are all about water and so is life. The equation is very simple: no water equals no life. Whether we’re talking about drinking water, food production or storing carbon emissions, humankind needs healthy, thriving wetlands.

And so does the rest of life on Earth. Wetlands are vital for biodiversity: although freshwater wetlands cover less than 1% of the planet’s surface, 40% of all species rely on them.

But despite their importance, wetlands are in big trouble. The Wildfowl and Wetlands Trust (WWT) estimates that 87% of the world’s wetlands have been lost over the last 300 years, with vast swathes being drained for housing, industry and agriculture. Those wetlands that remain often suffer from serious pollution, and are also threatened by climate change.

Monty

The Ramsar Convention, which dates from 1971, seeks to secure international agreement and co-operation to protect wetlands. And yet, despite no fewer than 171 countries signing up to this intergovernmental treaty, the loss of – and damage to – wetlands across the globe continues unabated, with an impact on biodiversity that’s difficult to overstate. In this context, World Wetlands Day and similar initiatives – both large and small – are to be welcomed as a means of raising awareness of the continuing wetlands crisis.

* * *

Mrs P and I are big fans of wetlands, which offer superb opportunities for birdwatching. We are lifetime members of the WWT, a UK-based conservation trust which seeks to “conserve, restore and create wetlands, and inspire everyone to value the amazing things healthy wetlands can do for us.”

Sadly we live around 90 miles (145km) from the nearest WWT reserve, so our visits aren’t as frequent as we’d wish. But every visit we’re able to manage is worth the effort, none more so than our 2014 trip to the Slimbridge reserve in Gloucestershire. Here we were able to witness first hand the positive impact of the Great Crane Project.

Eurasian cranes are unmistakeable birds, standing more than four feet (1.2m) high, with slate-grey plumage, a red crown and a bold white streak extending from the eye to the upper back. They were once common in British wetlands, and countless place names – like Cranford in West London, close to where I grew up – include the element ‘cran’ to signify a locality where these majestic birds were known to congregate.

But loss of habitat due to the drainage of wetlands led to a decline in numbers, and hunting made things even worse. For example, in 1251 King Henry III served 115 cranes at his Christmas dinner, while in 1465 a feast to celebrate the enthronement of George Neville as Archbishop of York involved the consumption of 204 cranes. I can only hope these medieval displays of unrestrained gluttony were followed by unrelieved bouts of chronic indigestion…serve the buggers right, I say!

Unsurprisingly, by around the year 1600 cranes had become extinct throughout Britain. They remained absent from the British landscape for nearly 400 years.

In 1979 a small number of cranes crossed the sea from continental Europe to settle in the Norfolk Broads. They began to breed three years later, but the location was kept secret to avoid the unwelcome attention of egg collectors. The population survives, and has crept into other parts of East Anglia and a few other isolated spots in eastern Britain. But cranes mature slowly and typically have poor breeding success, with the result that after around 40 years the descendants of the Norfolk population remain pitifully small in number.

Chris(tine)

With the prospect of cranes naturally recolonising other parts of their ancestral range being remote, conservationists needed an alternative strategy if the bird was to spread in reasonable numbers to wetlands in the west of Britain. And thus was born the Great Crane Project, with the aim of establishing a self-sustaining breeding population of 20 pairs on the Somerset Levels by 2025.

The project saw a coalition of conservation organisations (WWT, RSPB, the Pensthorpe Conservation Trust and Viridor Credits) join forces to work on this highly ambitious, ground-breaking project. Each year between 2010 and 2014, around 20 Eurasian crane eggs were taken under licence from Brandenburg in Germany to be hatched in the UK. In all, 93 chicks were carefully raised in captivity. Dedicated “human parents” hand-reared the youngsters, educating them in the ways of the world at “crane school” before releasing them into the wild on the RSPB reserve at West Sedgemoor on the Somerset Levels. Simultaneously, work was undertaken at some sites to restore and improve the habitat for cranes.

* * *

When Mrs P and I visited Slimbridge WWT reserve in 2014, the prospect of seeing cranes never entered our heads. We’d previously enjoyed a couple of fleeting, distant views of cranes in East Anglia, but it seemed wildly improbable that any birds from the Great Crane Project would end up at Slimbridge, around 66 miles (106km) from where they were released.

And yet, amazingly, we were treated to fantastic views of a pair of cranes, strutting, preening and displaying just a few metres from where we were sitting. What a privilege, to spend an hour in such close proximity to majestic birds that once graced British wetlands in huge numbers, but which are now so scarce.

Monty

The coloured rings on the cranes’ legs make it possible to identify the individual birds we saw that day: the Great Crane Project website confirms them to be Monty and Chris(tine). Theirs was one of the first breeding attempts by any of the birds released as part of the Great Crane Project, but sadly they failed to raise any youngsters, either in 2014 or subsequent years.

The 2020 Annual Report, authored by Elizabeth Antliff-Clark and Damon Bridge from the RSPB, indicates that the cranes released between 2010 and 2014 have so far fledged 31 youngsters, of which 27 are still alive. Sadly 2020 was not a particularly good year for breeding success. The annual report tells us

“27 pairs of breeding age birds were observed in 2020 – two more than last year. Of these, all 27 pairs were thought to be holding territories. 15 pairs made confirmed or probable breeding attempts. Because monitoring activities were minimal on account of the Covid 19 restrictions, there were a higher proportion of pairs in the ‘possibly bred’ category than in previous years so it is likely that this confirmed/probable figure would have been higher in a ‘typical’ year. Nine of the 15 pairs successfully hatched chicks with four of these going on to fledge.

The 15 confirmed and probable nesting attempts this year were made on the Somerset Levels and Moors (7 prs); WWT Slimbridge Reserve Gloucestershire (5 prs); Oxfordshire (2 pr); Cambridgeshire (1 female).”


SOURCE: The Great Crane Project 2020 Report Public Version (section 4.1), published on Great Crane Project website, retrieved 28/01/21

The report goes on to suggest that the explanation for 2020’s poor success rate lies in the near-drought conditions experienced at the time, which led to the drying-out of nest-sites and an increase in predation. If this is correct then last year’s poor performance may be regarded as a blip, and improved breeding success can reasonably be anticipated in 2021.

Let’s hope so. Cranes are a welcome addition to the biodiversity of British wetlands. If the Great Crane Project succeeds in its ambitions the species will continue its slow recovery from nearly 400 years of local extinction, allowing many more birders – and ordinary members of the public – to marvel at the sight of these magnificent birds. Wouldn’t that be an achievement for wetlands conservation!

* * *

STOP PRESS: Just as I was about schedule this post for publication I picked up a press release from the RSPB / Crane Working Group. It reports that “the latest common crane survey reveals a record-breaking 64 pairs of cranes in 2020, bringing the total population [across all of the UK] to over 200 birds.” This number includes the birds released as part of the Great Crane Project and their descendants, and the descendants of the birds that returned naturally to the Norfolk Broads in 1979. The 64 pairs produced a total of 23 chicks.

What brilliant, timely news! There are bound to be bumps along the road, such as the drought that coincided with the 2020 breeding season, but taken as a whole the prospects for cranes in the UK look better than at any time since the Middle Ages. Give Nature half a chance, and She WILL fight back.

A touch of the exotic: the Mandarin Duck

As the UK’s first Covid lockdown began to ease last June, one of our earliest trips out was to Straws Bridge nature reserve close to the small Derbyshire town of Ilkeston. It’s known to locals as Swan Lake because … well, because it’s a lake that boasts several handsome swans amongst its residents. The swans were out in force when we visited, but were overshadowed in our eyes by the unexpected sight of a family of mandarin ducks.

Mandarins favour small wooded ponds and avoid large expanses of open water, so the Straws Bridge reserve is ideal for them. Comprising three modest bodies of water set in a landscape of mixed woodland and meadows, it’s one of those habitats that shows how nature can bounce back when man lends a helping hand. In the 1970s and 1980s the area was scarred by open cast coal mining, but when the company concerned got into financial difficulties the local council took it on and restored the site as a wildlife habitat and local amenity. 

We’ve visited this reserve many times over the years and have always found it busy with families out for a stroll, often with a loaf of bread in hand to feed the swans and ducks and – inadvertently – sustain the burgeoning rat population at the same time.

In June last year the place was heaving with visitors, all grateful to get into the open air after the relaxation of the government’s stay-at-home Covid restrictions. None of them, other than Mrs P and I, appeared to have a clue that they were in the presence of a bird that’s regarded by many as the world’s most beautiful duck.

Mandarin ducks look far too exotic to be native British birds, and that’s absolutely right. They hail from East Asia – China, Japan and eastern Russia. The male sports a bright red bill, a reddish face with a large white crescent above the eye, a purple breast with two vertical white bars, and ruddy flanks. It also has two orange “sails” at the back. These comprise large feathers that stick up like the sails of a boat, and are perhaps the most eye-catching feature of what is a very elaborate bird.

The female, however, is drab, with a grey head, brown back and mottled flanks. Her white eye-ring and stripe can’t disguise the fact that, in common with the females of most duck species, she’s unremarkable.

Although the disparity in their looks might suggest otherwise, eastern folklore tells us that a pair of mandarins make the perfect couple. The birds are said to mate for life. In traditional Chinese and Japanese culture, mandarin ducks are therefore regarded as symbols of marital faithfulness. They are a favourite of artists, and also feature in Buddhist legends where they are said to represent compassion.

Male and female. No prizes for guessing which is which!

The supposed everlasting bond between mandarins is captured in a Japanese folktale, which begins with a great lord capturing a male bird so he can forever enjoy its beautiful plumage. Separated from its mate, the male is desperately lonely and begins to pine away. Seeing that the bird will soon die of a broken heart, the lord’s maidservant and her samurai lover decide to do the decent thing and reunite the lovelorn pair. However they get caught in the act and the furious lord condemns them to death for their treachery, proving beyond all doubt that for mankind and birdlife alike the course of true love does not always run smoothly!

* * *

It was in the mid-18th century when mandarins were first brought to Britain, with the intention of adding a bit of oriental glamour to the ornamental waterfowl collections of the idle rich. They escaped with monotonous regularity, and sometimes were deliberately released, but it wasn’t until the 1930s that a significant self-sustaining population of feral birds became established.

Juvenile mandarin

Since then numbers have grown rapidly, and there are now reckoned to be close to 8,000 mandarin ducks scattered widely throughout England. There are also feral populations in parts of continental Europe, as well as California and North Carolina in the US.

Spotting a lucrative gap in the market, China exported tens – or perhaps hundreds – of thousands of mandarins over several decades. Although the trade was banned in 1975 its impact, combined with widespread habitat loss, has resulted in a big fall in the wild Chinese population. Luckily mandarin ducks are reputed not to taste very good, otherwise pressures on the wild population would have been even greater in a country with over a billion mouths to feed.

Mandarins are notable for perching in trees, and the female invariably chooses a hole or cavity in a tree trunk in which to lay her eggs. After hatching, the ducklings jump to the ground and avoid injury thanks to the cushioning of their fluffy down. The mother swiftly gathers her brood together, and leads them to water. At Straws Bridge the female had plainly done a good job, and we got clear – although distant – views of some juveniles.

However, without doubt the male is the star of the mandarin show. What a looker!

Celebrating National Robin Day

The good folk at SongBird Survival (SBS), an independent charity which funds research into the declining numbers of Britain’s songbirds, have declared next Monday – 21 December – to be National Robin Day. And who can blame them? The instantly recognisable robin has an appeal that extends way beyond dedicated birders, so celebrating this bird table superstar is an inspired way of gaining more publicity for their worthy cause. To mark the day, I thought I’d share some random facts and folklore about this iconic bird.

1 Robins are British Christmas card icons

It’s no accident that the SBS chose mid-December as the best time to celebrate National Robin Day. In Britain robins have been associated with Christmas since the 19th century, when postmen were dubbed robin redbreasts because of their red tunics. The mail they delivered at Christmas brought happiness to householders across the country, and the link was quickly made between redbreasts and seasonal merriment. Robins soon started appearing on Christmas cards, and they’ve been there ever since.

Worthy of a Christmas card

2 The naming of robins

The original English name for the robin was purely descriptive: our ancestors called it the redbreast. But they got it wrong. Even a cursory inspection in good light will reveal the bird’s breast to be orange, or perhaps an orangey-red, rather than pure red. The word orange, describing a colour, was unknown in English until the 16th century when it appeared as the name of the now-familiar citrus fruit. But by this time earlier generations had already adopted the next most appropriate word in the language – red – to describe the colour of the robin’s signature plumage.

The word robin, when applied to the bird, emerged in the 15th century when it became popular to give human names to familiar species. This new practice resulted in the birds becoming known as robin redbreast, which was eventually shortened to robin

3 The robin is Britain’s unofficial National Bird

In the 1960s the Times newspaper organised a poll of its readers to find Britain’s most popular bird, and the robin came out on top. Around half a century later, in 2015, popular birdwatcher and author David Lindo organised a similar survey. Over 200,000 people took part and the robin won again, having received 34% of votes cast, ahead of the barn owl (12%) and the blackbird (11%). Despite these public votes the UK government has remained on the fence and, for now at least, officially we don’t have a National Bird. Unofficially, however, the robin clearly takes the title.

4 Robins are nestbuilding mavericks

When it comes to choosing a place to nest, robins aren’t fussy. Just about anywhere will do. Most commonly their nests can be found about two metres off the ground, within some kind of hollow or crevice and sheltered by vegetation. But others will nest on the ground, perhaps behind the overhang of a grassy tussock, or occasionally beneath fallen twigs covered by leaf litter.

However, radical freethinkers within the robin population choose to nest amongst the flotsam and jetsam of human life. Old teapots, discarded kettles, watering cans, coat pockets, wellington boots, farm machinery, flowerpots, hats, barbecues, an unmade bed and the body of a dead cat have all been selected by robins as a suitable place to bring up a family!

Although their nestbuilding strategy may seem bizarre, it delivers the goods. There are estimated to be 6,700,000 breeding territories in the UK. Since 1970 the robin population has increased by around 45 per cent.

5 Male and female robins both have vivid breast plumage

Robins are highly territorial, and – particularly in the breeding season – adult males like to show off their vividly coloured breasts in an attempt to intimidate other males. Although females are less competitive, they too have orangey-red breasts. The two sexes look very similar, and their brightly coloured breast plumage got them into trouble towards the end of the 19th century when robin skins were for a time a popular adornment for ladies’ hats.

It’s worth noting that juvenile robins have a speckled brown breast and don’t develop the species’ distinctive plumage until after their first moult. The youngsters therefore belong to the group that is the nemesis of birders everywhere: they are Little Brown Jobs.

6 Robins sometimes fight to the death

You wouldn’t think it to look at them, but robins are aggressive little birds prone to acts of violence. It’s all about territory. It begins with a singing contest, males belting out their songs at one another while trying to get to a higher perch from which to flaunt their brightly coloured breasts. If one or the other doesn’t back down the dispute can become physical, resulting in injuries and even – on occasion – the death of one of the combatants. Shockingly, in some populations, up to 10 per cent of adult mortality is due to these avian turf wars.

7 Robins, friends to gardeners everywhere

Putting aside the connection with Christmas festivities, another reason for the robin’s popularity is its confiding nature. The robin presents as a friendly, trusting bird, more so than any other species that regularly visits British gardens.

Gardeners in particular often get up close and personal with robins. As ground feeders, robins enjoy nothing more than cheekily scavenging earthworms and other invertebrates dug up by gardeners going about their business. They’re also regular visitors to bird tables during the winter months, feisty feeders that aren’t shy about claiming their share of the feast.

Interestingly, robins are less confiding on continental Europe. This is thought to be because in many parts of the continent, particularly in the southern part of the robin’s range, the locals have the detestable habit of hunting small birds. It therefore pays the robin to keep its head down, skulking in the undergrowth, where hunters are less likely to find them. In Britain, where this horrible hunting tradition doesn’t exist, there is no evolutionary incentive for such caution.

The robin is a regular visitor to British bird tables

8 How the robin became

Unsurprisingly for a bird that associates so closely with humans, many stories have grown up to explain the robin’s distinctive colouring. One legend says that when Jesus was dying on the cross, a robin flew to his side and sang into his ear in order to comfort him. At this point the robin’s plumage was a dull, unremarkable brown colour. However the blood from Jesus’ wounds stained the robin’s breast. In that moment the world welcomed its first robin redbreast, and from that day onwards all robins bore the mark of Christ’s blood.

An alternative version of this tale tells us that one day an ordinary brown bird was flying high over Golgotha, near Jerusalem, when it looked at the ground below and spotted Christ suffering on the cross. Determined to ease Jesus’ torment it flew down and tried to remove His crown of thorns, but as it tugged in vain at the cruel affliction some of the Lord’s blood stained its breast. And this was how the robin became.

A third robin creation myth also makes a link between Jesus and the robin’s colouration. According to this story, shortly after Mary had given birth in the Bethlehem stable a small brown bird appeared and – in a noble attempt to keep the Christ Child warm – started to fan the flames of the dying fire. However, embers from the fire scorched its chest feathers, leaving the bird red-breasted. Mary saw what had happened and declared that the red breast was a sign of the bird’s devotion to the Lord. She went on to promise that the bird and all its descendants would forever onwards wear a red breast in memory of this selfless act of love.

9 Q: When is a robin not a robin? A: When it’s an American robin

The species of robin seen in British gardens is found all over Europe, extending as far east as Western Siberia and south to North Africa. Robins are also found in North America…or are they? Well, no, actually they’re not. The American Robin isn’t really a robin at all, and belongs instead to the thrush family. Early European settlers in the Americas, desperate for reminders of home, noticed its reddish coloured breast and named it after the bird they knew from back home. Ornithology plainly wasn’t their strong point as, other than the colour of the breast, the two species bear little resemblance.

Interestingly, in the 1964 movie Mary Poppins starring Julie Andrews, the director got the wrong bird. Despite Dick van Dyke’s laughable attempt at a London accent, Mary Poppins is clearly set in England. However the bird that lands on Mary’s finger during the song A Spoonful of Sugar is an American Robin rather a European robin. Why am I not surprised by Hollywood’s cavalier relationship with factual accuracy?

The American Robin…is not really a robin at all!

10 Who killed cock robin?

The robin appears in the well-known English nursery rhyme Who Killed Cock Robin?, a gruesome tale describing the murder and the funeral of a robin. The unfortunate redbreast is shot by a sparrow, and subsequent verses reveal who organises his funeral, who digs his grave and who plays the role of chief mourner. The person who concluded that such a verse constitutes suitable entertainment for children was clearly in need of therapy.

The nursery rhyme first appeared in print in 1744, in a volume entitled Tommy Thumb’s Pretty Song Book. However the story appears already to have been an established part of England’s oral tradition. A stained glass window dating from the 15th century and showing a robin killed by an arrow can be seen Buckland Rectory (Gloucestershire), while in the early 1500s John Skelton wrote and published a similar story called “Phyllyp Sparowe.”

There are now multiple versions of the nursery rhyme, some of which have been put to music. My favourite is by the American folk-singing duo Dana and Susan Robinson. They are brilliant performers – we’ve seen them perform on a couple of occasions in the UK – and for us Who Killed Cock Robin? is always the highlight of their gigs.

So, dear reader, as you reach the end of this little post, please join me in celebrating our National Robin Day by listening to Dana and Sue’s rendition of the tragic tale of one robin’s untimely end, courtesy of the YouTube link below.

Isle of Man highlights – (3) Black Guillemots at Peel Harbour

The Black Guillemot isn’t a rare bird. Many thousands breed in the British Isles – the RSPB estimates 19,000 pairs in the UK – scattered along the coast in pairs or small groups. And ours is just a small part of the world population, which is estimated at between 260,000 and 410,000 pairs: these striking seabirds are also found around the coasts of the North Atlantic and Arctic Oceans, across Siberia to eastern Russia and Alaska. The species is rated as Least Concern by BirdLife International.

We’ve previously encountered Black Guillemots at various locations in Scotland, where they are relatively common, particularly in Orkney and Shetland. Here the bird is known as the Tystie, a name derived from Norse, the language of the Vikings who settled in the Scottish islands many centuries ago. A similar name is still applied to the bird in Iceland and Norway.

Black Guillemots are also found around much of Ireland, on the Anglesey coast in north Wales and at a few spots in northern England. Around 300 pairs breed on the Isle of Man, where you’d be hard pressed to find a better place to watch them than at Peel Harbour.

The hustle and bustle of fishing and recreational vessels at Mann’s busiest port makes Peel Harbour an unlikely place for these distinctive seabirds to thrive. But thrive they do. Away from human settlement they breed among rocks at the base of cliffs, or in the shelter of boulders on rocky islets, but at Peel, gaps in the harbour wall offer an attractive alternative. They appear completely at home here.

During our visit in June 2018, the Black Guillemots at Peel Harbour were displaying their distinctive breeding plumage: black all over, with a large, white oval patch on each wing. The bill matches the black plumage, but when the bird opens its mouth a bright red gape is revealed. The legs are also a vivid red. However, outside the breeding season the Black Guillemot loses its good looks, turning white, with black barring on its back, and black wings.

Peel Harbour gave us our best ever views of these splendid birds, and it was fascinating to watch them strutting their stuff, resting up and posing on the fishing boats in the harbour. They were clearly oblivious to the human activity all around them, not to mention the admiring looks of birders like us! You can enjoy a glimpse of their antics on my YouTube video:

A Red Kite comes calling

One of the inevitable consequences of the Covid-19 lockdown is that we’ve spent pretty much every moment of the last three months at home. Planned visits to Cornwall (2 weeks), Norfolk (10 days) and Liverpool (5 days) have all been abandoned, while day trips we would have done to places closer to Platypus Towers have also been impossible. Our horizons have been severely limited by the crisis.

However, it’s not all bad news. Spending more time chez nous has enabled us to better appreciate the wildlife that visits our garden.

We live deep in a suburban housing estate, and our private outdoor space isn’t big – just 90 square metres. Nevertheless, ten species of butterfly have passed through in recent weeks, and despite the best efforts of visiting cats Milky Bar and Malteser to have them for dinner, various birds have also dropped in, tempted by a well-stocked birdtable. A few months ago I wrote in this blog that birds don’t come here anymore, so the return of our feathered friends has been very welcome.

But the very best garden wildlife encounter has been courtesy of a Red Kite, swooping so low over us that it almost seemed we could reach up and touch it. It didn’t stay long, probably no more than 30 seconds, so no chance for photos or video, but the encounter is etched indelibly into the memory. We have been in this house since the mid-1980s, and if anyone had suggested then that one day we’d experience a fly-past by a Red Kite we’d have assumed they were completely out to lunch.

Amongst our collection of books about birding we have a field guide published in the year we moved into this house. It describes the Red Kite as uncommon, with fewer than 45 breeding pairs in the country. The distribution map shows the species confined to the mountains of mid-Wales, around 150 miles (240 km) from Platypus Towers.

But fortune has looked kindly upon the Red Kite over the last 30 years, thanks primarily to a spectacularly successful reintroduction programme.

Red Kites were once found throughout England, Wales and Scotland, both in traditional countryside haunts and in urban settings. They were so common that William Shakespeare described London as a “city of kites and crows.” Kites were welcome visitors to towns, where they scavenged waste discarded by the inhabitants, and this avian garbage disposal service was so highly valued that the birds found themselves protected by an English Royal Charter in the 15th century!

But times changed, and these impressive raptors were transformed from heroes into villains, being seen as a threat to food supplies and to game shooting interests. Intense persecution followed, and around 150 to 200 years ago Red Kites became extinct in England and Scotland, clinging on only in remote, mountainous areas of mid-Wales. Remarkably, genetic fingerprinting tells us that the entire relict Welsh population were descendants of a single female, an indication of how close the bird came to extinction in Wales too.

Numbers of Red Kites stabilised in Wales, but although the bird was given legal protection and some nests were protected from egg collectors it seemed unlikely that the growth in numbers would ever be sufficient to allow successful recolonisation beyond its borders. Further intervention was required if England and Scotland were to re-establish their own populations, and eventually the RSPB and English Nature (now Natural England) stepped up to the plate.

Their ambitious reintroduction programme began in 1989, with birds taken from Sweden – and later, Spain – released at sites in southern England (Buckinghamshire) and northern Scotland (the Black Isle). Other release sites came on stream later in the project, which lasted more than two decades, creating extra hubs from which the rest of the country could be recolonised.

By any standard, the Red Kite reintroduction programme has been a spectacular success. Under the heading “a triumph for conservation,” the RSPB website reports that there are now around 46,000 breeding pairs in the UK.

The birds still face threats, in particular “illegal poisoning by bait left out for foxes and crows, secondary poisoning by rodenticides, and collisions with power cables,” but the Red Kite’s situation has improved out of all recognition since the reintroduction programme began.

Although we were lucky to get good views of a Red Kite flying over Platypus Towers a few weeks ago, I imagine it will be some time before they become a regular sight here: recolonisation is a gradual process. However there are places in the UK where sightings are pretty much guaranteed, particularly in Wales, which is home to around 50% of the entire UK breeding population.

Indeed, Red Kites have become a tourist attraction in Wales, with one enterprising farmer turning them into a major business opportunity. Gigrin Farm’s website says:

We are a 200 acre family-run working farm, now famous for our Red Kite Feeding Centre. Hundreds of Red Kites feed here every day. It is a truly breathtaking spectacle which we hope you will come along and witness for yourself.

They do not exaggerate. I’m pleased to report that Gigrin Farm offers spectacular, close-up views of an extraordinary number of Red Kites, as well as a glimpse of the rare white-morph Red Kite and sundry other birds including buzzards, ravens and rooks. The photographs illustrating this post were taken by Mrs P when we spent an afternoon at Gigrin in November 2018.

Although the farm is currently closed to visitors due to Covid-19 restrictions, the birds continue to be fed. When regulations allow I would happily recommend anyone with a passion for Red Kites to visit Gigrin Farm…you won’t be disappointed!

Reflections on World Penguin Day

What is it about penguins? Everyone loves a penguin. Who can look at a penguin for more than a couple of seconds without chuckling, or shaking their head in admiration? I guess part of the reason could be that, walking upright, they remind us of ourselves, becoming avian caricatures of waddling human determination. Or is it their lifestyle that appeals, their battle with the elements, their ability to survive and thrive in huge, crashing seas and monstrous, crushing cold?

Penguins: cultural icons, and very tasty chocolate-covered biscuits! P..P..Pick up a Penguin!

Whatever the reason, penguins are deeply embedded within our culture, loved by wildlife enthusiasts, writers of children’s books, makers of animated movies, and marketing men the world over.

And, of course, biscuit-loving Brits. In the UK, Penguin biscuits, or cookies as our American cousins would describe them, are a popular, chocolatey treat. For decades the McVities marketing department has urged us to P..P..Pick up a Penguin, and we’ve obliged … in our millions!

So, given their status as cultural icons, it’s no surprise that penguins have been granted their own “World Day” on the 25th of April every year, to celebrate their lives and to raise awareness of their conservation needs.

The world is home to somewhere between 17 and 20 species of penguin today (typically, the scientists can’t make up their minds!), the majority of which are on the IUCN (International Union for the Conservation of Nature) Red List of Threatened Species. Over the years Mrs P and I have been lucky enough to see four penguin species in the wild. However we’ve never seen them against a background of ice and snow, an indication that the shared cultural image of penguins in a frozen landscape is too simplistic.

In fact, our very first sighting of a wild penguin was on the Galápagos Islands, within spitting distance of the equator. The Galápagos Penguin is one of the world’s rarest – the rarest according to Wikipedia, although other sources disagree – and the only one to venture into the northern hemisphere. It survives in tropical waters thanks only to the cooling Humboldt and Cromwell currents, and in an El Niño year – when the water warms up – the population comes under threat.

Galapagos Penguin: 48 cm tall, weight around 5.5lbs

During the 1982/83 El Niño numbers fell by around 77%, and although there has been some recovery since then, according to the WWF the total world population remains below 2,000 individuals. Mrs P and I were privileged to visit Galápagos in 1989, and had the extraordinary experience of swimming alongside penguins in a remote, beautiful bay.

It would be 27 years before we’d see wild penguins again, this time in Tasmania. The Little Penguin goes by various other names, including Fairy Penguin in Australia and Little Blue Penguin in New Zealand. The names are a clue to the bird’s defining characteristics – at 33 cm in height it’s the smallest of all penguin species (the Galápagos Penguin is the second smallest), and its plumage is a distinctive slaty-blue colour.

Colonies of Little Blues exist along the southern coast of Australia, and all around the coast of New Zealand. By comparison with the Galápagos Penguin these birds are plentiful, with numbers estimated in 2011 at between 350,000 to 600,000. However they are in decline, and are particularly vulnerable in their mainland breeding grounds. On uninhabited offshore islands they fare better.

Our best penguin encounter in Tasmania was in the northern town of Stanley where we were, quite literally, almost tripping over and driving round them as they clambered out of the sea to return to their burrows under cover of darkness. You can read about this very special evening here, in my blog of our epic Tasmanian adventure.

On reflection, the behaviour of the Little Blues in Stanley highlights their vulnerability in areas settled or visited by humans. Many of their burrows are some way inland, sometimes in the gardens of local residents, and the daily journey to and from them is fraught with perils. These include marauding dogs, sneaky cats and speeding cars. All things considered, it’s a tough life, being a Little Blue and living on mainland Australia and New Zealand!

Our 2019 trip to New Zealand was timed to maximise the chance of seeing the Fiordland Crested Penguin, which is endemic to the country and breeds in small colonies on inaccessible headlands and islets along the shores of south-western South Island, and all around Stewart Island. They nest in rock crevices or hollows beneath tree roots in coastal forests. Eggs are laid in late August, and hatch after a period of 32 – 35 days. Two eggs are laid, but typically only one per clutch will hatch.

A Fiordland Crested Penguin makes landfall!

Chicks are guarded by the male and fed by the female for the first three weeks, at which point they are left unattended and typically form small crèches. Both parents continue to feed the chick(s) until they fledge at around 75 days old in late November or early December.

Mrs P and I were pleased to see Fiordland Crested Penguins on several occasions, on land and occasionally swimming offshore. Our best view was courtesy of an experienced wildlife guide, who led us on a tortuous trek through the bush, fording a stream on several occasions, until we reached a secluded bay where we could watch the comings and goings of the parent birds.

A Fiordland Crested Penguin returns to the ocean, grubby from its overland journey

Upon making landfall the birds preened themselves carefully and checked their surroundings for potential predators, then set off on their journey, trudging stoically inland. Standing around 71 cm tall, they are more than twice the size of Little Blues. When walking their posture is stooped, like that of an old man hunched over his walking stick, but although they look ungainly and uncomfortable Fiordland Crested Penguins can make steady progress on land.

Pretty soon the penguins we’d been watching reached the spot where the beach ends, and the hillside begins. Then, like intrepid mountaineers, they began to climb the steep slope along a well-worn track. As they did so they passed other birds that were making their way back down from the crèche site to the sea after feeding their chicks. The constant coming-and-going was hypnotic, and we watched spell-bound for around 90 minutes until it was time for us to leave. You can read more about this, one of our best birding experiences ever, in this post from my New Zealand blog.

The Fiordland Crested Penguin walks with a distinctive stooped posture

The current population level is unclear; surveys in the 1990s counted 2,500 pairs of Fiordland Crested Penguins, though this was likely an underestimate. However numbers are believed to be declining due to human disturbance, predation by introduced mammals such as dogs, cats, rats and stoats, and fishing industry by-catch. The species is classed as vulnerable to extinction by the IUCN, and New Zealand’s own Department of Conservation changed its status from vulnerable to endangered in 2013.

New Zealand’s third, and rarest, penguin is the Yellow-eyed. In 2018/19 there were only 225 breeding pairs on mainland South Island, the lowest level since 1991 Most sources – although not Wikipedia – regard it as the world’s rarest penguin.

Perhaps in response to its plight, the Yellow-eyed Penguin has recently achieved celebrity status by being voted New Zealand’s 2019 Bird of the Year in a poll organised by the conservation organisation Forest & Bird. It’s the first time in the poll’s 14 year history that a seabird has emerged victorious, and the fact that a penguin is the first to break through the glass ceiling is further confirmation of the special appeal of these birds.

A Yellow-eyed Penguin emerges from the sea, dripping like Ursula Andress in that James Bond movie

The Yellow-eyed Penguin is slightly taller than the Fiordland Crested, standing at around 76 cm. It nests in clumps of flax, scrub and forest close to the shore, often in a scrape lined with grasses, against a tree trunk or log. Nests are always hidden away from other nesting pairs, and the bird communicates with a high-pitched scream. They are not very sociable.

The BBC website’s report of the Bird of the Year poll result is headed “Rare anti-social penguin wins New Zealand poll.” I can’t help thinking that Yellow-eyed Penguins came up with the concept of social distancing long before Covid-19 reared its ugly head!

Given its rarity and celebrity status we were very keen to become acquainted with the Yellow-eyed Penguin, and so were delighted to encounter them at a couple of locations on the south-east coast of South Island. Again our best views were achieved courtesy of experienced wildlife guides, and this time we were witnesses to a heart-in-mouth drama.

While the sealion is distracted, this Yellow-eyed Penguin follows a fence-line to return to its chick

At a private reserve on the Otago Peninsula we watched spellbound as a bird emerged from the waves, dripping seductively like Ursula Andress in that James Bond movie, only to find its way blocked by a hungry sealion. It scuttled back to the waves, swam along the beach a little way, then made another landfall.

Again it stopped in its tracks, judging the sealion was too close and too ravenous for safety. Time and again it tried, only to slam quickly into reverse before the sealion gave chase; we watched intently, hoping for the best but fearing the worst. You can read all about it here. SPOILER ALERT: the penguin finally made it safely to the forest, and the sealion went hungry. Phew!

Meanwhile at the other end of the beach another Yellow-eyed Penguin, perhaps seeing that the sealion was distracted, waddled casually up the beach and along a fence-line before disappearing into the bush, giving us outstanding views as it passed. It was the last penguin we would see on our New Zealand odyssey, and a reminder of why these iconic, intrepid, flightless birds have been granted their very own “World Day.”

World Curlew Day

Yesterday – 21 April – was World Curlew Day! It probably passed you by: let’s face it, the news media are concentrating pretty much all their attention on one topic right now, understandably focussing on Coronavirus rather than curlews. Environmental issues aren’t perceived as a priority today, but while we follow the life and death struggle of fellow citizens coping with the COVID-19 virus, this magnificent bird is engaged in a battle of its own. Curlews are in big trouble.

The curlew is the largest of all European waders, an unmistakable bird with a brown body, long legs and a diagnostic downward-curving bill. And then there’s its liquid, evocative and haunting call.

Curlews overwinter on tidal mudflats and saltmarshes, and this is where Mrs P and I mostly see them, during our winter birding breaks. They used to breed widely both in upland and lowland Britain, but changes in farming practices have massively reduced lowland breeding success.

There are reckoned to be around 65,000 breeding pairs of Eurasian Curlews in Britain. Sounds like a lot, doesn’t it, until you realise that this is a reduction of about 65% since 1970. And given that Britain accounts for around a quarter of the world breeding population of these birds, the decline here is bad news for the species as a whole.

In 2008, Eurasian Curlews were added to the IUCN’s (International Union for Conservation of Nature) Red List of birds deemed to be of global conservation concern, becoming officially classified as “Near Threatened.”

Ours is not the only species of curlew under threat. A century ago the world boasted eight species of these large, long-lived waders. Today there are only six, of which three are on the Red List. As a group, they are claimed to be among the most threatened migratory birds on Earth. In response to their plight the first World Curlew Day was announced in 2018.

World Curlew Day has been described as “a grassroots initiative supported by environmental organizations such as BirdLife International and Wetlands International. It is a one-day global event aiming to raise awareness about the plight of curlews and to encourage activities to help them.” This blog post is my own modest contribution to the World Curlew Day initiative.

*

The RSPB (Royal Society for the Protection of Birds) website summarises what is believed to be behind the decline of the Eurasian Curlew, noting that “the evidence to date suggests declines are largely due to poor breeding success alongside the loss of breeding grounds.” It continues:

“Like many wading birds, curlews lay their eggs in a nest on the ground – known as a ‘scrape’. The parents incubate the eggs for about four weeks, before the young leave the nest and roam around with their parents for a further four weeks, until fledging

Studies from across Europe have found that in most cases breeding pairs are failing to raise enough young to maintain stable populations.
 
Egg predation by mammals and birds has emerged as a key factor behind poor breeding success. However, this abundance of predation is in itself associated with changes in land-use and management.
 
Farming is essential to maintain the mosaic of grassland and wetland habitats curlews need, but large-scale grassland improvement ultimately leads to the degradation and eventual loss of breeding habitat. Changes in grazing pressure can also have a more direct impact in the form of nest trampling by livestock.”

SOURCE: RSPB WEBSITE, retrieved 18 April 2020

Having identified the problem, the RSPB is now urgently seeking a solution. Its Curlew Recovery Programme is undertaking research to better understand the management practices required to reverse the decline in Eurasian Curlew numbers. At the heart of the programme is a Trial Management Project.

The Trial Management Project is carrying out work at sites across the four countries of the UK, looking at a range of possible interventions including habitat management and targeted predator control. Baseline monitoring at the six sites in Scotland, England, Wales and Northern Ireland was undertaken during the 2015 breeding season, and research to identify and develop appropriate “curlew-friendly” land management strategies is continuing.

*

In a separate project, the WWT (Wildfowl and Wetland Trust) started work last year on a project to protect curlews in the Severn and Avon Vales.

“The plan is to throw everything we’ve got at the problem in the vale. Curlew protection will be driven by farmers, that’s the logical reality. If we can work with them to turn things around here, that’s a great start. But we also want the vale to be a test ground for ideas that could be rolled out elsewhere and, ultimately, incorporated into new government agri-environment policy, so that farmers can effectively be paid for curlew-friendly management.”

SOURCE: GEOFF HILTON, WWT’s Head of Conservation Evidence, quoted in Waterlife: The WWT Magazine, April/June 2020, page 36

When a curlew nest is located within the study area, the WWT researchers must weigh up carefully the risks and benefits of intervention. Approaching the nest may alert predators to its existence, or may disturb parent birds and cause them to abandon it. However if the risks of predation are high, the project team may decide that, on balance, the interest of the birds is best served by approaching to erect an electric fence around the nest in an effort to keep foxes and badgers at bay.

The scientists are also keen to collect data that will give them a better understanding of the challenges to be overcome in halting the decline in curlew numbers. To this end researchers may visit the nest briefly to weigh the eggs and deploy a temperature logging device; the data collected can provide valuable insights into laying and hatching dates, and incubation patterns. The nest may also be visited again, just before the chicks fledge, to ring and radio-tag the birds so that further information on their progress may be collected at a later date.

The WWT’s most drastic intervention of all is “headstarting,” where vulnerable eggs and chicks are removed from the wild to be raised in captivity, before being released in a more favourable location. The recent article in Waterlife magazine describes the removal of 50 curlew eggs from airfields in East Anglia, where they would have been destroyed to prevent airstrikes. After being hatched and raised by the WWT, the young birds were released in the safer surroundings of its Slimbridge Reserve. A good news story, if ever there was one!

In doing my research for this post I’ve been shocked at the plight of the curlew, which is worse than I’d realised. It’s a bird I love to watch, and the prospect of its becoming extinct is heart-breaking. However the levels of work currently underway to better understand the problems it faces, and to find appropriate solutions, give me cautious grounds for optimism. I wish the researchers every success in their endeavours.
