In this week’s programme Brett travels to Gambia in search of songbirds which any day now, will leave their winter home and head north for Britain. We join a team of scientists in New Zealand where they’ve been catching and attaching transmitters to Bar-tailed Godwits (the wading birds which hold the record for the longest non-stop flight) so we can follow their journey to Alaska and back. And here in Britain, there’s the launch of a competition to spot the first spring migrant arrive.
