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.

Tropical birds live longer than temperate counterparts

An international research team has found strong evidence that passerine birds near the equator live longer than their higher latitude counterparts.

Their findings, published today in the journal The Auk: Ornithological Advances, underscore the pervasiveness of broad latitudinal patterns in avian life history. The article summarizes six years of bird survey results from a tropical forest site near Manaus, at the center of the Amazon basin, and compares the Manaus results with findings from eleven other sites over a latitude span of more than sixty degrees across the Americas.
