It is 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. They are joined by Steve Backshall, the first in a series of special guests on the show this year, and by Gillian Burke, who spends the next three weeks travelling the length of the UK - starting at its northern tip in the Shetlands, where she hopes to see killer whales.
