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.

Flight delays: Study finds out why some African birds stay home longer

Summary:
Parents of millennials still living at home aren't the only ones with children that refuse to leave. Many animal species have adult offspring that are slow to take flight, but when and how they leave has been poorly understood by scientists. Now, new UBC research on a desert-dwelling African bird is yielding some answers.

Martha Nelson-Flower, a postdoctoral fellow at UBC, studied the behaviour of wild southern pied babblers, which live in family groups of up to 14 in the Kalahari Desert in South Africa. Her findings, published in the Journal of Animal Ecology, suggest that better prospects elsewhere, as well as family dynamics between brothers and stepfathers, play a big part in determining when offspring disperse.
