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.

Genes tell story of birdsong and human speech

Summary:
A massive international effort to sequence and compare the entire genomes of 48 species of birds, representing every major order of the bird family tree, reveals that vocal learning evolved twice or maybe three times among songbirds, parrots and hummingbirds. Even more striking, the set of genes employed in each of those song innovations is remarkably similar to the genes involved in human speaking ability.
