What does the Cassin's vireo sound like?
Bird vocalisations are usually divided into songs – longer, often complex phrases used to defend territory and attract mates, sung mostly by males in the breeding season – and calls: short, simple sounds for contact, alarm, begging or flight.
The recordings here are labelled as song and subsong. Listen for differences in rhythm, pitch and repetition – the spectrum display makes it easy to see whether a sound is a pure whistle (a thin line), a harsh call (a broad band) or a trill (rapid repeated marks).
