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.

Researchers estimate size of bird with unusual vocal biomechanics by its song


by Bob Yirka ,

A team of researchers from Universidad de Buenos Aires, Museo Argentino de Ciencias Naturales and the University of Münster accurately estimated the size of a white-tipped plantcutter bird by studying nothing but its song. In their paper published in the journal Physical Review Letters, the group describes their study of the unique bird and is raspy cry.

The white-tipped plantcutter is a songbird found in the scrub and woodlands of south-central and south-eastern South America. It is a member of the Cotingidae family, is sexually dimorphic and eats mostly leaves. What makes it truly unique, however, is how it produces its songs.
