As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Later supper for blackbirds in the city: Artificial light gives birds longer to forage for food

Summary:
Artificial light increases foraging time in blackbirds. Birds in city centers are active not just considerably earlier, but also for longer than their relatives in darker parts of the city. The study showed that artificial light has a considerable influence on the activity times of blackbirds in the city and therefore on their natural cycles.
