BBC Radio 4’s ‘Inside Science’ last night was interesting. Amongst other things, it had a piece about work that Lund University in Sweden is doing on the life of swifts. They have put some tiny data loggers on some birds and then retrieve them when the birds return to nest the following spring. They have brought to light new information about the birds flying time and their whereabouts in their African winter quarters. Do listen!
