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.

Geographic variation in Gentoo penguin calls

Summary:
Vocal communication is central to the lives of many birds, which use sound to attract mates and defend territories. Penguins are no exception, but we know little about how or why penguin vocalizations vary between isolated populations. A new study takes a broad look at vocalizations across the range of Gentoo penguins and concludes that while their calls do vary from place to place, we still have lots to learn about the processes at work.
