What does the Grey-crowned flatbill sound like?
Birds produce sound with the syrinx, a vocal organ deep in the chest that can make two independent sounds at once. Songs tend to be long and patterned and are used to hold territory and attract a mate; calls are short signals for contact, alarm and flight.
The recordings here are labelled as song, call and calls. 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).
