Overview: Chris Packham and his stepdaughter Megan McCubbin continue their a wildlife-watching road trip round Britain, this time exploring the Lake District. They take two alpacas for a short walk and a paddle in Derwentwater, before heading off in search of the elusive red squirrel, and going to a bar with a live badger-cam. Chris then takes Megan to Walney Island, one of his favourite places, where they catch sight of grey seals, eider ducks and terns
