Blakeney Point seals its place in the record books

The grey seal rookery has increased remarkably since it was established in 2001, when just 25 pups were born. Passing the 2,000 mark in 2012 and reaching 2,453 in 2014. Now after two years of relative stability, the rookery has grown again to a new record breaking peak. 

National Trust rangers monitor the colony by counting and recording seal pups born at Blakeney Point throughout the winter. The count, which began on 23 October 2017, was a record in itself, as this was the earliest date for a grey seal birth on the Point, by three days.
 

The perfect breeding site

Although we can’t say for certain what’s led to this record breaking year at Blakeney Point, the reserve is the perfect breeding site for grey seals, not least because of the absence of predators and the relative remoteness which keeps disturbance to a minimum. 

There’s also plenty of space to support the large numbers of seals on the sandy beach, with sheltered sand dunes further inland adding additional protection from bad weather. It’s also worth noting that the east coast has escaped some of the worst storms to hit the UK this winter, with grey seal rookeries on the west coast faring less well following Hurricane Ophelia in October.

Most of the seals will spend the majority of the year foraging for food across the North Sea. But females tend to return to the same breeding sites year after year. With increasing population numbers in recent years and those females now reaching breeding age, it’s a contributing factor to the colony’s increasing size. Also, with a mortality rate of less than 2.5% this winter, Blakeney Point continues to be a healthy, successful and productive rookery.

What do we know about the new arrivals?

Grey seal pups are born on land, with white coats and are fed on their mother’s rich milk for up to three weeks. In this time, they triple in size and shed their white fur.

The mother then leaves the pup to fend for itself and usually by this stage she is exhausted and starving, so heads to sea to feed.

How are seals faring elsewhere?

Elsewhere, seal colonies have fared well around the UK this year. 

The National Trust’s Farne Islands off the Northumberland Coast reported high numbers with the arrival of 2,010 pups. Donna Nook, which is cared for by the Lincolnshire Wildlife Trust saw births pass the 2,030 mark for the first time and a record 1,820 pups were counted further along the Norfolk coastline at Horsey.
