Band-tailed sierra finch sounds

About the Band-tailed sierra finch

The Band-tailed sierra finch is a bird in the family Thraupidae (order Passeriformes).

What does the Band-tailed sierra finch 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. 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).
