Episode 1

It's May Bank Holiday and Springwatch is back for a special 90-minute opening show - broadcasting live from the Sherborne Park Estate in the Cotswolds. Chris Packham and Michaela Strachan host, with a plethora of live cameras trained on brand new nests across the Gloucestershire countryside, with blue tits, marsh tits, treecreepers and a gorgeous little owl.

They are joined by Steve Backshall, the first in a series of special guests, who is investigating the Sherborne Brook and some of the small but vitally important creatures that live here.

Gillian Burke, who will spend the next three weeks travelling the length of the UK, is starting at its northern tip in the Shetlands, where she hopes to see killer whales and looks at the vitally important seabird colonies on these islands.

With films about a stunning butterfly conservation success story, ravens setting up home on the Gower peninsula in south Wales, and the wildlife to be found in Richmond Park in London, it's an action-packed 90 minutes.
