Searching for seals (timing is everything!)
We recently spent a couple of days searching for seals. It’s not difficult if you know where to look, particularly at this time of year. There are a few UK beaches where grey seals haul out in large numbers, the females to give birth to new pups and the males to mate with those females as soon as they’re given the opportunity.

The UK’s grey seals are a conservation success story. Back in the early 20th century just a few hundred made their home here. Today, the total stands at around 120,000, which accounts for roughly 40% of the entire world population.

The recovery of these impressive marine mammals in the UK is thanks largely to a change in the law in 1970. Before that date the seals were heavily persecuted by fishing communities, which regarded them as pests. The new law gave them protection for the first time, allowing them to get on with their lives as nature intended.

The boom in grey seal numbers has made it easier for members of the public to get up close and personal with them. But improved access also increases the risk of disturbance, and to help mitigate this “seal wardens” are on hand at several beaches to watch over them and intervene when problems arise.




At the water’s edge. Grey Seals at Horsey Gap, 4 November 2024
One of these beaches is at Horsey Gap on the north-east coast of Norfolk. When we visited earlier in the month the wardens were doing a great job of telling people more about the seals under their protection. We learned that…
- male grey seals (bulls) live up to 25 years, reaching sexual maturity at six years. Females (cows) can live up to 35 years, and start to breed at some point between the ages of three and five years.
- grey seals can dive to depths of 300m, and stay under water for around 20 minutes.
- grey seal milk contains up to 50-60 % fat, ten times more than a Jersey cow’s milk.
- when they are born pups weigh around 13kg, but just three weeks later they weigh around 45kg.
- female grey seals abandon their pups after suckling them for just 17 to 23 days. The pups stay behind on the beach, living off their fat reserves, for another three weeks while they moult off their white coats and grow a grey waterproof one.
- adult cow seals weigh up to 250kg, while bulls weigh up to 350kg (to put this into context, former world heavyweight boxing champion Mike Tyson weighed in at a mere 103kg for his controversial fight with Jake Paul in Dallas on 15 November 2024!).

Our visit to Horsey Gap was towards the start of the pupping season, meaning that we saw fewer adult seals than we’d hoped, and just a couple of white-coated pups. In the winter 2021/21 season, 2,500 pups were born at Horsey and nearby Winterton, so clearly the best was yet to come. But although not the spectacular sight we’d expected, it was still a great experience to watch them squabbling in the waves and chilling out on the beach.

Adorable! Donna Nook, 27 November 2015
It was a similar story at Donna Nook, an area of Lincolnshire coastline that is well known for its grey seals. Unlike Horsey Gap, which was new to us, we have previously visited Donna Nook on a couple of occasions. When we were there in mid November 2014, and again in late November 2015, large numbers of adult seals were hauled out and many fine looking pups were on show, the epitome of adorable cuteness. Even better, the seals were lying at the very top of the sweeping sandy beach, almost within touching distance of fascinated onlookers who were gathered behind the wire fencing that kept the two parties apart.

This year, however, we visited very early in November 2024, and at the time of our visit only a few grey seals had so far arrived for the pupping season. More disappointing still, those that were there had settled down close to the water’s edge and were therefore a very long way from their human audience. The warden explained that it would take a high tide, and perhaps a day or two of stormy weather, to drive the animals further up the beach to a place where they would be easier to observe.

We left Donna Nook a little deflated. Our previous visits encouraged us to expect much more, but the experience is a clear reminder that, when you watch wildlife, timing is everything. We got it slightly wrong this year. Oh dear, we’ll just have to go back!

Luckily, Mrs P took lots of great seal photos on our two previous visits to Donna Nook, and I have used some of them to help illustrate this post. They are a clear demonstration that, if you get the timing right, watching grey seals at pupping time is one of the UK’s great wildlife spectacles.
