Grey partridge makes comeback on farm land

The grey partridge was once plentiful but numbers have dropped dramatically since the 1950s as a result of intensive farming and the use of pesticides.

Since the 1990s some farmers have taken advantage of EU and government grants to take small areas of land out of production to help the bird.

Naturalist Chris Packham visited the Duke of Norfolk's Sussex estate, where 12% of farm land has been sacrificed to help the grey partridge - with impressive results.
