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.

Summary:
Some people say that we become more like our partner as time goes on. Surprisingly, the same seems to be true in the animal world -- studies on compatibility between mates show that individual animals are more successful when they behave in a similar fashion to their mate. New research shows that mating pairs of the bird species known as great tits become more similar in their hormones over time.
