The first grey seal pups of the year born at one of England’s largest colonies will be the first counted in an annual survey.

The National Trust, which manages the Farne Islands off the Northumberland coast, carries out the yearly census to monitor the mammals’ numbers and health and to gather data to help direct conservation efforts.

The charity has been using drones since 2018 to provide more accurate data with minimal disturbance to wildlife.

Area ranger Sophia Jackson said “each pup born here is a testament to the conservation work we do”.
