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.

Climate change does not bode well for picky eaters

Gentoo Penguin at Cooper Bay, South Georgia.jpgChinstrap Penguin.jpgIn a part of the world that is experiencing the most dramatic increase in temperature and climate change, two very similar species of animals are responding very differently. New research suggests that how these species have adapted to co-exist with one another might be to blame.

Chinstrap penguins whose namesake describes the black stripe under their chins are decreasing in number while Gentoo penguins, recognizable by their bright orange beaks, are increasing at summer breeding colonies in the Antarctic Peninsula. This research sheds light on the different strategies these two similar species have carved out over time to reduce competition for food, and the ramifications these different strategies are having now during a time of rapid environmental change.
