Migration – the lengths that some creatures go to.

I have become a huge fan of podcasts in the last few months, one of which I subscribe to being the BBC’s best of Natural History Radio. The last two weeks have been ‘World on the Move’, a series looking at the migration of species around the world.

Some of the highlights have included a visit to Gambia to look for the warblers that will be returning to the UK to breed in the Summer – it certainly puts a different slant on things to hear about ‘African’ rather than ‘British’ Chiffchaffs and Whitethroats. Apparently the Housemartins already appear to be on the move north. We are also asked to look out for Painted Lady butterflies and report in our first sightings of them. These amazing creatures migrate over from Africa – 1000 miles; there are networks of people looking for them all the way from Spain through Europe, they have even managed to reach Sweden in the past! Not bad for such a fragile-looking creature. However, one of the hardiest creatures is possibly the Alaskan Bar-Tailed Godwit. One of these was tagged and flew non-stop from Alaska to New Zealand, 11,700 kilometres in 8 days – not surprisingly she now holds the record for the longest non-stop flight. I think you have to agree that this is pretty amazing.

Should you want to find out more there is a lot of interesting information on the BBC website – http://www.bbc.co.uk/radio4/worldonthemove
