Autumnwatch returns for a celebration of UK wildlife.

Chris Packham and Kate Humble visit Strangford Lough in Northern Ireland - more than 50 square miles of inland seawater, described as one of Europe's most important wildlife sites. For Chris, the star attraction is 30,000 light-bellied Brent geese - that's three quarters of the world's population. Kate decides to go deeper, diving beneath the waves in search of conger eels.

In Northumberland, wildlife sound recordist Chris Watson is on an audio journey from source to sea of the river Coquet. Closer to home Martin Hughes-Games is on the trail of the best of your stories. Show less
