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.

Barn owl nestlings recognise their siblings' calls

Barn owl nestlings recognise their siblings' calls, according to researchers.

Instead of competing aggressively for food, young barn owls are known to negotiate by calling out.

A team of scientists in Switzerland discovered that the owlets have remarkably individual calls.

They suggest this is to communicate each birds' needs and identity in the nest.

The findings were announced in the Journal of Evolutionary Biologyby Dr Amelie Dreiss and colleagues at the University of Lausanne, Switzerland.
