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.

Worsening wind forecasts signal stormy times ahead for seabirds

Summary: Stronger winds forecast as a result of climate change could impact on populations of wild animals, by affecting how well they can feed, a study of seabirds suggests.

Research into a common UK coastal seabird showed that when winds are strong, females take much longer to find food compared with their male counterparts.

Researchers expect that if wind conditions worsen -- as they are forecast to do -- this could impact on the wellbeing of female birds, and ultimately affect population sizes.

In many seabird species, females are smaller and lighter than males, and so must work harder to dive through turbulent water. They may not hold their breath for as long, fly so efficiently nor dive as deeply as males. The latest results suggest that in poor weather conditions, this sex difference is exaggerated.
