Great Yarmouth little terns get beach patrol
Volunteers on the beach to help rare birds
May 2009. Volunteers will be busy on the beach at Great Yarmouth until mid-August, helping to protect the UK’s largest colony of little terns.
A team of volunteers and wardens from the RSPB and Natural England will be putting up a 700 metre fence on North Denes beach to protect the rare seabirds as they lay their eggs on the beach. The team will patrol the beach night and day to ward off predators and keep the eggs and chicks safe from harm.
This summer will be the 23rd year of the scheme to protect little terns at Great Yarmouth and Winterton Dunes. The joint efforts of the RSPB, Natural England and Great Yarmouth Borough Council help to protect the vulnerable birds from predators and disturbance while they raise their chicks.
300 pairs of little terns
Every May, around 300 pairs of little terns make the arduous journey from Africa to nest on the beach at North Denes and at Winterton Dunes National Nature Reserve. North Denes hosts the largest breeding colony of little terns in Britain, with around 10% of the UK population choosing to nest at this site.
There are now about 60 little terns in Langstone Harbour, many of which are exploring the new shingle areas, with some already sitting on nests: here.
