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:
'Attractive' male birds that mate with many females aren't passing on the best genes to their offspring, according to new research that found promiscuity in male birds leads to small, genetic faults in the species' genome. Although minor, these genetic flaws may limit how well future generations can adapt to changing environments.
