Springwatch returns with the best of the UK's wildlife - live. Stories include the strange late spring of 2013, red kites, wild boar, dolphins and otters. Chris Packham, Michaela Strachan and Martin Hughes-Games follow all the action from the live nest cameras, and reveal some exciting new locations at the stunning Ynys-hir reserve in mid-Wales. They also kick off the BBC's Summer of Wildlife Season, helping celebrate, discover and meet our wildlife neighbours. (R)
