Watch Autumnwatch

Chris and Michaela present the final instalment of the wildlife dramas at Wild Ken Hill.

At Wild Ken Hill in Norfolk, Chris reveals images of animals at night taken by a thermal camera, while Michaela heads to the coast to find out why the Wash is awash with migrating birds at this time of year. Megan takes a dip in shark-infested waters in Scotland, Gillian looks into the genetics of red squirrels and there's an autumn assassin in the shape of a wasp spider.

In this episode, there's a woodland symphony composed using the sounds of fungi, and Chris and Michaela search for signs of the beaver kit born at Wild Ken Hill. Gillian gets stuck into the importance of mud at Strangford Lough, while in Scotland, Megan checks out how hedgehogs are doing on Mull. And there's a Mindful Moment from the beautiful lakes and mountains of Cumbria.

Autumnwatch returns for a week of live wildlife stories from across the UK. Chris Packham and Michaela Strachan are at Wild Ken Hill in Norfolk to see what's changed since spring and to revel in the Snettisham Spectacular - an autumn highlight in the birding calendar.
