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.

Song experiments reveal 21 possible new tropical bird species

Summary:
Birds often choose their mates based on song, making it a key factor in separating species. However, analyzing spectrograms can only tell us so much -- the characteristics that birds hone in on when identifying potential mates may not be the same ones scientists notice in audio recordings. A new study uses field experiments to 'ask the birds themselves' and uncovers as many as 21 previously unrecognized species.
