Seal pups have been recorded at South Walney Nature Reserve, one appearing a month earlier than usual. The pupping season here in Cumbria generally runs from October to mid-November, but this year, the first pup was spotted on 31 August. A second pup was born three weeks later, on 17 September.
Beth Churn, Marine Conservation Officer for Cumbria Wildlife Trust said: “The first seal pup was a lovely late summer surprise! It’s not the first time that we’ve seen seal pups this early in the season, but generally we spot them from October through to November.
“There are various possible reasons why the first pup arrived early. It could be climate change effecting prey availability and sea conditions.
“The pupping season varies from region to region so it may be that the mother has come from a nearby colony (for example North Wales or The Isle of Man) where it’s not so unusual to see pups earlier.
“This year, unusually early grey seal pup births have also been recorded in Cornwall and on the Isle of Man so It seems like this may be a UK-wide trend.”
“We encourage anyone who wants to see the seal pups at South Walney to watch our live sealcam and keep an eye on our social media channels for videos and photos. Please note there is no access to the beach where the seals haul out.”
While October to mid-November is generally the pupping season at South Walney, it is sometimes earlier. For example, in 2021, the first pup was recorded on 27 August.
Earlier this year, we counted a record number of grey seals at South Walney Nature Reserve: a total of 563 seals. The previous highest grey seal counts were 518 in 2021, 483 in 2019 and 360 in 2018, showing an upward trend year on year.
This is the 11th year running that pups have been recorded for Cumbria’s only breeding grey seal colony. The seals started breeding at South Walney in 2015 and pups have been recorded every year since. This success story isn’t accidental but is the result of concerted and ongoing efforts to minimise disturbance of the seal colony. We work hard to make the site safe and secure for the seals, so that they feel able to return here to breed. This includes keeping disturbance to a minimum.
The best way to see the seals and their pups is to follow us on social media and watch our live sealcam. Alternatively, visitors to South Walney can watch the seals in the sea at high tide from a safe distance in Groyne Hide (you’ll need binoculars or a viewing scope to see them). Please note there is no access to the beach where the seals haul out.
We appeal to all sea users, including kayakers, anglers, jet skiers and boats, to maintain at least 100m distance from the seal colony at all times. Good views of the seals can easily be had using binoculars from a safe distance, and there's no need to get too close. Generally, you’ll know if you’re too close because the seals will start to look at you and move nervously. If this happens, you should immediately start backing away quietly to avoid further disturbance. More guidance is available here Marine & Coastal Wildlife Code.
