The number of grey seal pups born at one of England's largest colonies has hit a record high.

Surveys by rangers have shown the number of youngsters born on the Farne Islands off Northumberland has risen by almost 50% in five years.

Some 2,602 Atlantic grey seal pups were counted in the latest breeding season on the islands, up from 1,740 in 2014.

The National Trust said a good supply of food and fewer predators were behind the rise in numbers.

Atlantic grey seals are protected mammals, with global numbers thought to be around 300,000 - half of which live in British and Irish waters.

Rangers who live on the Farne Islands for nine months a year survey the seals during the breeding season, which runs from late September to December, with the majority of pups born in October and November.

Once the breeding season starts, pups are sprayed with a harmless vegetable dye to indicate the week they were born, with a rotation of three or four colours helping rangers keep track of numbers.

Drones have also been used to help monitor pups for the first time.

Ranger Thomas Hendry said: "A lack of predators and a plentiful supply of sand eels, which make up about 70% of the seals' diet, has helped bolster our seal pup numbers.

"This new record for the grey seal colony is certainly a milestone and could be good news for the health of our seas around the islands."

"Over the next few years we will monitor the effect of a growing seal population and to manage the island habitats accordingly," he added.
