Autumnwatch returns for an eight week celebration of UK wildlife.

New presenter Michaela Strachan joins Chris Packham and Martin Hughes-Games, broadcasting live from the National Arboretum at Westonbirt. They'll be sharing their adventures from the previous few days.

This week, their journey takes them to the spectacular Wye Valley, on the trail of wild boar, swarming bats, and autumn's wild harvest. Meanwhile, guest presenter and naturalist Roy Dennis is following the perilous migration of the Springwatch osprey chicks as they leave our shores and head for Africa.

Chris Packham, Michaela Strachan and Martin Hughes-Games broadcast from the National Arboretum at Westonbirt, with all the latest autumn wildlife action. The team report back on the glorious autumn colours and wildlife of the ancient woodlands, and the drama of the fallow deer rut, seen during their trip to the Cotswolds. Plus an exclusive look at wildlife gardening at the famous Highgrove Estate, and guest presenter Leah Gooding investigates the plight of one of our most mysterious and iconic fish, the eel.

Chris Packham, Michaela Strachan and Martin Hughes-Games broadcast live from the Wildfowl and Wetlands Trust's Slimbridge reserve.

There's a report on the Bewick swans as they arrive to spend the winter at Slimbridge, and guest presenter and naturalist Roy Dennis is on the trail of the Springwatch ospreys as he follows their perilous migration all the way to Africa.
