More than 150 harvest mice have been reintroduced to a nature reserve in west London - 45 years after the species was last recorded there.

The animals became extinct in the borough of Ealing, with the last official sighting at Perivale Wood in 1979.

It is the fifth site the mice have been released as part of the Ealing Wildlife Group rewilding project.

It aims to create an improved ecosystem for plant and animal life.
