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.

Male Spectacled Warblers Are Innovative Singers

Jan. 14, 2014 — The variability in the song of the male spectacled warbler could play a crucial role in mating, defending territory and recognition between individuals of this species. Studying their acoustic signals will help to understand how this bird, with a small brain and limited social needs, can use a complex system of communication.

Each male specimen of spectacled warbler, Sylvia conspicillata, has a complex, diverse song, in which new syllables are added and the order is changed as they go along, with a level of skill that relies on their capacity for innovation. Spanish scientists have characterised the acoustic signal of this species, its virtuosity and variability, to try to understand the role that this signal plays in mating, defending territory and recognising individual birds.
