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.

Summary:
Carbon, nitrogen and sulphur stable isotopes analysis is an effective technique to reconstruct nestling Bonelli’s Eagle diet, according to a new paper. Diet analyses are central to the study of avian trophic ecology and can be an important conservation tool. Despite the high number of studies on Bonelli's Eagle (Aquila fasciata) diet developed in Western Europe, eagle's relationship between prey consumption and vital parameters remains unknown.
