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.

Birds retreating from climate change, deforestation in Honduras cloud forests

Bird diversity shifts upslope in tropical mountainous terrain

The cloud forests of Honduras can seem like an otherworldly place, where the trees are thick with life that takes in water straight from the air around it, and the soundscape is littered with the calls of animals singing back and forth.
Otherworldly, yes, but scientists have found that the cloud forests are not immune to very down-to-earth problems of climate change and deforestation. A 10-year study of bird populations in Cusuco National Park, Honduras, shows that the peak of bird diversity in this mountainous park is moving higher in elevation. Additional land protection, unfortunately, may not be enough to reverse the trend, driven in part by globally rising temperatures. The study is published in Biotropica.
"A lot of these species are specialized to these mountain ranges," says study lead author Monte Neate-Clegg, a doctoral student at the University of Utah, "and they don't have a lot of options as to where to go should things go wrong."
