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.
