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.

Natural selection causes early migration, shorter parental care for shorebirds

Summary:
All bird migrations are fraught with danger – from the risk of not finding enough food, to facing stormy weather, and most importantly – trying not to be eaten along the way. Raptors such as peregrine falcons are the main predators of migratory birds, and huge flocks of congregating shorebirds can be easy pickings. In a new paper, researchers provide new evidence that shorebird species can adopt substantially different ways of dealing with this predation pressure.
