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. In Northern Ireland, Gillian Burke digs deep into how moles cache worms for the cooler months, and Megan McCubbin is live from the Isle of Mull, a place famous for its eagles, red deer and otters.
