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.

Love at first smell: Can birds choose mates by their odors?

Summary:
Mate choice is often the most important decision in the lives of humans and animals. Scientists have found the first evidence that birds may choose their mate through odor. The researchers compared the preen gland chemicals of black-legged kittiwakes with genes that play a role in immunity. Kittiwakes that smell similarly to each other also have similar genes for immunity. Since the birds prefer to mate with unrelated mates, the scientists have now found the likely mechanism by which they recognize relatedness.
