Tomorrow (Tuesday) at 11.00 on Radio 4 "live from the BBC Natural History Unit" is the 24th edition of World on the Move, and the last before a 4 week break. It will return on 2nd September and will broadcast weekly until December 16th.
Tomorrows show is anchored, as ever, by Philippa Forrester and the NHU's very own Brett Westwood. And you'll also hear from two other members of staff: A thrilling piece about Humpback Whales bubble netting in Alaska reported by Joe Stevens (Natures Great Events) and the third instalment from Grant Sonnex as he follows the migration of Salmon through the river systems of Alaska. We also have our World on the Move scribe Paul Evens delivering his prose on the show - And a fascinating insight into how Alaskan Bar-tailed Godwits sustain their migration between Alaska and NZ.
So an Alaskan fest as a mark of poignancy for this hugely important part of the world for migrating animals. And all can be seen and heard on www.bbc.co.uk/worldonthemove
And you can listen to the 21.00 repeat on Wednesday or hear elements of the programme on World Service Science in Action.
