Celebrating World Wetlands Day with the heron family

Posted on by Platypus Man

Last Monday, 2 February, was World Wetlands Day. A wetland is a transitional area between land and water, an area where water covers the soil – or is present at or near the surface – either permanently or seasonally. Mrs P and I love a good wetland: it’s a distinct ecosystem that is a great place for a spot of birdwatching, and is notable as the favoured habitat of the handsome heron family

Grey Herons were my Mum’s favourite bird. This one has just caught itself a tasty snack.

When my father died over 30 years ago we bought my mother a set of binoculars and started taking her out on our birdwatching expeditions. She soon declared the heron to be her favourite bird, attracted I suspect by its large size and a distinctive appearance that includes a dagger-like bill, long spindly legs and an improbably bendy neck. I imagine she was also intrigued by the birds’ hunting style, in which they stand motionless for lengthy periods before stabbing explosively at any prey item foolish enough to venture too close to them. Spotting a heron quickly became Mum’s ambition whenever we took her out, and because we chose our birdwatching sites carefully she was rarely disappointed.

The Grey Heron is the UK’s most common species of heron. As these images show, Mrs P’s been photographing them for many years.

The species that Mum got to know and love is the Grey Heron, by a long way the most common member of the heron family in the UK, with over 60,000 birds overwintering here. Standing nearly 1m high and with a wingspan approaching 2m, it is an impressive bird. It feeds primarily on fish, but also eats amphibians, ducklings and other small birds, and tiny mammals such as voles. Interestingly, Grey Herons sometimes temporarily leave their wetland habitats in favour of nearby agricultural fields which they scour for rodents in the immediate aftermath of the harvest.

Little Egret.

The UK boasts several other members of the heron family, although none is very common. The Bittern is vanishingly rare; Mrs P and I have rarely seen one, and have never got a decent photograph. Little Egrets were once common here, but were wiped out over 100 years ago thanks to the insatiable demand of the fashion industry for the birds’ elegant feathers. I wrote about the decline and fall of the Little Egret, and the important consequences this had on bird conservation in the UK, in a post I wrote in 2024.

Great White Egret.

Little Egrets began recolonising the UK in the late 20th century, and these days we see them quite often. Sadly their return came too late for my Mum, as did the more recent arrival of the Great White Egret. She would have been thrilled, I’m sure, to see both egret species, though I suspect neither would have supplanted the Grey Heron in her affections.

Across the whole world there are reckoned to be 75 separate species within the heron family, although some go under the names of egret or bittern. Herons’ solitary nature and their motionless hunting style have captured the imagination of cultures everywhere, often making them figures of mystery and deep spiritual significance as well as symbols of patience and wisdom. Every continent except Antarctica boasts resident species of heron, and as Mrs P’s photos show we’ve been privileged to see a number of these during our travels.

Clockwise from Top Left: Bare-Throated Tiger Heron (Costa Rica, 2008); Green Heron (Costa Rica, 2008); Bare-Throated Tiger Heron (Costa Rica, 2008); Indian Pond Heron (India, 2013); Little Blue Heron (USA, 2012); Great Blue Heron (Canada, 2012).

Almost all species of heron are closely associated with water, living and feeding as they mostly do on the margins of lakes, rivers, and swamps. They need wetlands, as do so many other species of birds, mammal and invertebrate, and it has been a pleasure to celebrate World Wetlands Day by featuring these magnificent birds here. My Mum, a heron lover until the very end, would definitely have approved!

Wordless Wednesday – Gotcha!

Posted on by Platypus Man

Wordless Wednesday is a simple blog post featuring a photo. It seeks to convey a message, but speaks for itself without using words. Mrs P took this photo of a White-Bellied Sea Eagle on the Arthur River in Tasmania, Australia in 2016.

A long way from home

Posted on by Platypus Man

At last, as the weather starts to improve, we take out first tentative steps back into nature. Poolsbrook Country Park, just a few miles from where we live, is a good place to start. Created on the site of a colliery that closed down in 1986, today Poolsbrook boasts a mosaic of habitats including lakes, wet grassland, wildflower hay meadows, woodland and hedgerows, all carefully managed for the benefit of wildlife. I have written previously about the Country Park’s history and key features.

We go to Poolsbrook quite often, and know what to expect. Our first visit of 2025 does not disappoint. All the usual suspects are on show, including Coot, Mallard, Great Crested Grebe and the inevitable Canada Geese. There are no rarities, but who cares – it’s just good to be out watching birds again after a long, miserable winter.

But what’s that? Cruising on the lake alongside a flotilla of Mallards is a duck we’ve never seen before. The head and neck are an iridescent blue-green colour, while the cheeks are white and the bill is bluish grey with a black tip. The breast is barred white and black, the flanks are orange-brown and the back is dark grey with white streaks.

We spend a lot of time watching birds in wetland habitats, and can readily identify most that we encounter. But this guy is a total mystery. Somehow it looks like a mixture of several other species, and we debate whether it’s some sort of weird hybrid. More research is clearly required, so as soon as we get back home we consult Professor Google.

The good professor reveals the truth. Our mystery bird is neither a natural hybrid nor the result of an unfortunate accident in a bio-lab. Instead, our investigation reveals it to be a Chiloé Wigeon. We learn that it is a very long way from home. Also known as the Southern Wigeon, the Chiloé Wigeon is native to southern parts of South America, its name coming from an archipelago lying off the coast of Chile.

Being relatively easy to care for, it appears that the Chiloé Wigeon is a popular bird in exotic wildfowl collections. The bird at Poolsbrook must be an escapee from one of these collections – it plainly has not arrived in this country naturally.

Further research reveals that the Poolsbrook bird has been in residence for well over a year. How did we miss it during all our previous visits, we wonder?

On reflection, I don’t know how I feel about seeing this unexpected bird on one of our local reserves. On the one hand, it is of course exciting to encounter a species that we will never see on its home territory, particularly as it is clearly thriving at the Country Park.

On the other hand, I can’t help thinking the bird might be better off back in South America, where it would be amongst its own kind and have the opportunity to breed. That, sadly, will not happen here and our Chiloé Wigeon will be unable to pass on its genes. Hopefully, however, it will continue to do well alongside its Mallard cousins at Poolsbrook. We’ll be sure to look out for it next time we visit.

Exotic no longer – the Great White Egret

Posted on by Platypus Man

Watching wildlife is addictive. Over several decades Mrs P and I have travelled the world to get our fix of animals and birds that we had no hope of ever seeing in the UK. Take Great White Egrets, for example. When we started our quest, they were impossible to find here. We encountered them first in the USA and India, and were well pleased with our achievement. And yet today we see them regularly in wetland habitats across the UK. The Great White Egret is exotic no longer.

At Nalsarovar Bird Sanctuary, Gujarat, India, 2013

The Great White Egret is a large, white heron. It is easy to distinguish from the Grey Heron, a species familiar to birders throughout this country, but can be confused with Little Egrets. The Little Egret is, as its name suggests, a good deal smaller than the Great White Egret, and has yellow feet and a black bill – the Great White, meanwhile, has black feet and a yellow bill. Confused? Me too! Numbers of Little Egrets have surged in recent years, something I wrote about in this post from 2021.

Seen in Texas, USA, 2012

Until around 15 years ago, Great White Egrets were impossibly rare visitors to these shores, and few birders ever got to see them. All that has now changed. The bird had been slowly expanding its range northwards and westwards in Continental Europe for some time, and around 2010 finally began to make the flight across the English Channel to see what the British Isles had to offer.

The key drivers behind the expansion in Continental Europe are unclear. Possible explanations include improvements to habitat, reduced persecution, and – inevitably – climate change.

At Attenborough Nature Reserve, Nottinghamshire, 2021

Whatever the reason, British birders are clearly beneficiaries. Accurate, up-to-date population data is difficult to track down, but it appears that overwintering Great White Egrets now number at least 100 individuals. They are most frequently found in south-east England and East Anglia, but are moving steadily northwards and can now also be seen in Scotland too.

At RSPB Welney Nature Reserve, Cambridgeshire, 2022

The species first bred in the UK in 2012, and there could now be more than 20 breeding pairs spread across the country. There is every likelihood that numbers will continue to grow for years to come, meaning that Mrs P and won’t be returning to the US or India when we feel the need to re-acquaint ourselves with this handsome heron!

My surprising discovery about Tufted Ducks

Posted on by Platypus Man

Tufted Ducks are a familiar sight at wetland habitats in our part of the UK. Although less plentiful than Mallards and Canada Geese, they are nevertheless a bird that I would expect to see whenever we visit local reservoirs, lakes and ponds. For me they are a fixture in our birding landscape. But, as I recently discovered to my surprise, that’s not quite true: Tufted Ducks, or “Tufties” as Mrs P and I prefer to call them, first arrived in this country less than 200 years ago.

Records suggest that Tufties started to colonise the UK in 1849. A few decades earlier the Zebra Mussel Dreissena polymorpha had been accidentally introduced into the country, and as this invasive species began to thrive Tufted Ducks followed in pursuit of a much-favoured source of food.

The number of resident Tufted Ducks in the UK grew steadily until at least the early 2000s, and it now breeds in most of England, as well as parts of lowland Scotland and localised areas of Wales and Ireland. The breeding population is around 18,000 pairs. In winter, numbers swell with the arrival of around 100,000 migrant birds from as far away as central Russia.

Male
Female

Male Tufties are handsome black-and-white birds, with a characteristic tuft and bright yellow eyes – totally memorable. Although the females also sport a tuft and yellow eyes, their drab buff-brown plumage renders them somewhat forgettable. Scouring Mrs P’s vast photographic archive, I discovered that nearly every photo that she’s ever taken of this species features the male. That, I think, tells you all you need to know about the differing visual appeal of male and female Tufted Ducks!

Tufties are fun to watch, busy little ducks that paddle swiftly across open stretches of water, before diving in pursuit of aquatic invertebrates and bivalve molluscs. It seems like they belong in this landscape and must therefore have been here forever, which makes it difficult to believe that British nature lovers at the start of Queen Victoria’s reign would have been denied the pleasure of their company.

The lesson to draw from this, I guess, is to remember that what we see today is just a snapshot in time. Species come and species go; it’s a natural process, although human activity speeds it up and can cause major instability. I wonder which birds species are entirely absent from the UK today, but will be taken for granted by British birders in the 22nd century?

The LBJ, the app, and the frustrations of birdwatching

Posted on by Platypus Man

Mrs P and I have been birdwatching for nearly 40 years. It’s a great way to pass the time, one that allows us to escape temporarily from the pressures of modern living and instead get up close and personal with nature. But it’s not without its frustrations, of which the most frustrating thing of all is the LBJ. And in case any Americans reading this are wondering, that has nothing at all to do with Lyndon Baines Johnson – aka LBJ – the 36th president of the US!

For the uninitiated, in the British birding community LBJ stands for “little brown job”, which Wikipedia tells us is “an informal name used by birdwatchers for any of the large number of species of small brown passerine birds, many of which are notoriously difficult to distinguish.” The problem is compounded by the fact that your average LBJ never sits still for long, instead flitting hither and thither between bushes, briars and other forms of cover. As a rule, you only get a fleeting glimpse of an LBJ before it goes back into hiding. LBJs are a birder’s worst nightmare.

An alternative approach to identifying LBJs is via their songs. Unfortunately Mrs P and I haven’t been listening carefully enough over the last four decades, with the result that the number of species we can identify by their song alone can be counted on the fingers of one hand. But – much to my amazement – modern technology has come to the rescue, in the form of an app on my mobile phone.

A casual discussion with a bird enthusiast last year first brought the Merlin Bird ID app to our attention. It’s dead simple, which is fortunate as mobile phones aren’t my thing. When a bird is singing just fire up the app, which will analyse the song against its database and tell you which bird you’re (most probably) listening to. Simple but effective, as we discovered last week, when it led us to identify our first ever Cetti’s Warbler.

The Cetti’s was heard – and briefly seen – just a few metres from this spot. Unfortunately Mrs P was unable photograph it, and I’m grateful to Mike Prince for the image of the illusive LBJ at the top of this post

Mrs P and I were at Straw’s Bridge – aka Swan Lake – a local nature reserve that I first wrote about nearly three years ago. We go there mainly to enjoy the wildfowl, but were intrigued this time by glimpses of an LBJ that we couldn’t identify, moving between a series of bushes by the edge of the lake. It proved typically illusive, but just when we were about to give up and move on the bird started to sing in short, loud bursts. I whipped out my phone, and in a just a few seconds we learned its identity.

For confirmation I cross-checked with other information provided by the app. Its photo of the Cetti’s clearly matched the brief glimpses we’d had of the bird, and the textual description of its appearance and behaviour was bang on: a “dumpy and broad-tailed warbler, warm brown above and pale grayish below, with a narrow eyebrow…favours tangled vegetation near water, including reedy marshes with bushes and scrub. Often heard but rarely seen. Explosive, rich staccato song often draws attention.” Follow the link below to hear the song of the Cetti’s Warbler’s.

I found this recording of a singing Cetti’s Warbler on YouTube, courtesy of Birdfun.

The species is a new arrival in the UK, first breeding here – in the south-eastern county of Kent – in the early 1970s. Since then its range has slowly expanded northwards, but until our LBJ encounter last week we’d no idea the Cetti’s warbler had reached our home county of Derbyshire. Without the help of the bird identification app we would probably never have known.

In principle, I would rather leave the modern world behind when I’m out in nature. Mobile phones have their place, but a birdwatching trip isn’t one of them…or so I thought until Merlin Bird ID helped us identify our first Cetti’s Warbler. Having seen that 21st century technology can help us vanquish one of birdwatching’s biggest frustrations – the LBJ – I guess I might need to revise my opinion.

The Big Garden Birdwatch breaks my heart

Posted on by Platypus Man

It’s that time of year again, the time when the UK’s dedicated nature lovers take part in the RSPB’s (Royal Society for the Protection of Birds) Big Garden Birdwatch, a national survey that has been running annually in one form or another since 1979. It is also, sadly, the time when I have to confess that once again Mrs P and I have failed miserably in our attempt to attract a wealth of birdlife to our modest suburban back garden.

The Woodpigeon was one of just two species to visit our garden over the Birdwatch long weekend

The first event, in 1979, was aimed at children and was a good deal more popular than anticipated. For over two decades the Big Garden Birdwatch continued in this form. Eventually the RSPB must have realised that the buzz created by the Birdwatch every year would be even bigger if anyone could take part, so in 2001 participation was opened up to adults as well. It worked: last year over half a million people took part in the Big Garden Birdwatch, and between them they recorded a massive 9.1 million birds!

The RSPB is understandably very proud of its Big Garden Birdwatch, which it claims is “the world’s largest garden wildlife survey”.  The benefits are wide-ranging: media coverage helps raise the profile of birds,- and environmental issues more generally – with a wider audience; those taking part get to focus their attention on nature for a while and enjoy consequential benefits for their mental health, and the RSPB collects a wealth of data on which species are thriving and which are struggling.

We were also visited by two male Blackbirds

Unhappily, the picture painted by the Big Garden Birdwatch is not encouraging, with the number of birds plummeting over the decades since it began. For example, House Sparrows are down 57% since 1979, while the number of Song Thrushes has collapsed by 80%.

Our own experience echoes these dismal findings: the results of this year’s count at Platypus Towers were, as expected, absolutely abysmal. The Big Garden Birdwatch 2024 ran over a period of three days, during which participants had to record the birds landing in their garden in a one hour period of their choice. In our garden, the number of birds seen throughout the whole three days – not just one hour! – was four. 

NOT SEEN! – Robin
NOT SEEN! – House Sparrow

Yes that’s right, we saw a measly four birds in our garden during the entire Birdwatch long weekend! OK, I admit that we weren’t watching every daylight minute of all three days, but the room where I work on my laptop overlooks the garden. In addition we spend every tea break in our “garden room”, watching what’s going on out there (and remember, we’re Brits so we have LOTS OF TEA BREAKS!) Not much passes us by, meaning the count of four birds is sure to be fairly accurate.

I’d been topping up the bird table for weeks to get the local birds in the mood for food, and on the first morning of the Birdwatch it was groaning under the weight of the goodies we’d provided. But they went largely ignored. The birds simply stayed away.

NOT SEEN! – Long-tailed Tit
NOT SEEN! – Wren

It wasn’t always like this. We’ve lived in this house nearly 40 years, and back in the day we welcomed a variety of avian visitors. Starlings, House Sparrows, Blue Tits, Long-tailed Tits, Robins, Wrens, Goldfinches and Dunnocks have all been seen. Memorably, for a few days one winter, a Pied Wagtail and a Grey Wagtail called our garden home. Once we spotted a Sparrowhawk sitting on the roof of the garden shed. A little later we found the remains of what we reckoned to be a Collared Dove on the path, and without doubt the Sparrowhawk was the guilty party. Even a Pheasant, hopelessly lost of course, once dropped in to say hi.

But in recent years, the number and variety of birds in our garden has fallen drastically. I last blogged about the Big Garden Birdwatch in 2020, under the title Birds Don’t Come Here Any More. That year, we saw just one male Blackbird! This year, between 26 and 28 January, the only birds to visit our garden were two woodpigeons and two male blackbirds. 

OK, we did better in 2024 than in 2020, but there’s nothing here to celebrate. I wish I could believe it’s simply because all the local birds got a better offer, a garden with tastier food (Mrs P’s theory) and fewer visiting cats, but I fear it’s worse than that. All the evidence suggests that bird numbers are declining right across the country. It breaks my heart.

NOT SEEN! – Pied Wagtail
NOT SEEN! – Grey Wagtail

Next year, of course, we’ll do the Big Garden Birdwatch again. Maybe we’ll do better than this time. We could hardly do much worse.

Update, 5 February 2024

A week has passed since I wrote this post at the end of the Big Garden Birdwatch, and as expected the birds are back in numbers. As well as the Blackbirds and Woodpigeons, over the last seven days we’ve been visited by a Starling and a Dunnock, and three (yes, that’s right, THREE) Robins. It’s almost as if they know and are taunting us. Huh!

Updating the update!

No more than 20 minutes after writing the above update two Blue Tits arrived and started inspecting the nest box we’ve put up on the side of the shed. They seemed interested. Things are definitely looking up, and my broken heart is beginning to mend…for now at least.

One year on …

The 2025 Birdwatch was marginally more successful: Two Woodpigeons, two male Blackbirds, two Robins and a Magpie. Typically, however, the Wren didn’t turn up until 48 hours after the count had ended. It was ever thus …
