19th of January: Oh buoy

Following the dispersal of most of the Grey Seals on Blakeney Point, this week we were finally able to help Blakeney Harbour Association retrieve the navigation buoy that washed up towards the end of last year during stormy weather.

Weighing 1.5 tonnes, this was no mean feat. The front loader on the National Trust tractor did the lifting and we were able to return it to Morston in our largest trailer.

Securing the buoy in the trailer

Trinity House will return the buoy to its location at the entrance to Blakeney Harbour from the North Sea (and strengthen its mooring), where it directs vessels around the Hjodis wreck. The sands have moved dramatically around the wreck over the past two years.

10th of January: Final count

We are delighted to announce that our final Grey Seal pup count for Blakeney Point in the 2017/18 season is 2,700 pups. This is a 12% increase on last season, and the largest increase in three years.

This makes it another record year for pup births, with 243 pups more than the previous record season (in 2014/15). As usual, mortality was low, with just 2.5% of pups not making it to the weaning stage.

Considering this was the greatest number of pups to ever be born on Blakeney Point in a season, we were pleased to only have to rescue one pup. In December, we rescued a newly weaned juvenile that had a nasty head wound. It has been doing well under the RSPCA's care at East Winch, where it has been named Naga.

The protective fences will remain up until 25th January to protect the later-born pups that are still reliant on their mother's milk to grow healthy and strong like the 2,000+ that have already been successfully weaned and dispersed into the North Sea. We ask that you please continue to respect these access restrictions. There are currently 199 pups and 59 adults on site.

As we reach the end of the Grey Seal pupping season, our work focus turns to practical habitat management work elsewhere on the reserve. This includes ditch clearance and reed cutting on the freshwater grazing marshes. We are also commencing our preparation work for the breeding bird season, which will soon be approaching.

31st of December: Tailing off

Seal pup births are tailing off. As we reach the end of the year, the birth rate has fallen to less than one a day.

There have been a total of 2,697 Grey Seal pups born between 18th October and 31st December 2017. There may be a very small number of pups born in January 2018, but this unlikely to be many more than just a couple.

UPDATE: 5th of January pup count takes total up by 2 to 2,699

9th of December: Twenty a day

Today's Grey Seal pup count revealed an average of 20 births a day since Wednesday's count (a 41% decrease in birth rate). These 60 new-born pups take the running total to 2,558 births so far this season.

There is now a pup and cow on the beach opposite the Hood; although bulls and weaned pups have made it this far down in previous seasons, this is the furthest east along Blakeney Point a pup has been born.
