Singing in the rainforest: Public vs. private signaling by a tropical rainforest bird

According to the Chinese proverb, a bird sings because it has a song, not because it has an answer. A team of French and Brazilian researchers, however, may have the answer as to how the song of Brazilian white-browed warbler has become so well-adapted to the acoustic properties of the rainforest environment. The study, led by Nicolas Mathevon and Thierry Aubin, is published in the online, open-access journal PLoS ONE on February 13.
