Bewick's swans have returned to Slimbridge Wetland Centre in Gloucestershire this week.

The migratory birds flew thousands of miles from northern Russia to spend winter in the UK.

Experts say this is one of the latest times in the year they have seen the birds arrive back.

Last year Slimbridge reviewed the swan count from the end of 2023 and found they have lost about 43% of their Bewick's swans over the last five years.
