American Tree Sparrow song and calls

Birdsong and calls are often the easiest way to identify the American Tree Sparrow, especially when the bird is hidden in dense foliage. Below is what to listen for.

Song

A sweet, tinkling, and musical song, often described as a series of clear, high-pitched whistles that descend in pitch, sometimes with a trill. 'Tsee-tsee-tsee-tew-tew-tew' or 'tiddle-ee-tiddle-ee-tew-tew'.

Calls

Common calls include a sharp, metallic 'tseet' or 'tink' call, often given while foraging or in flight. Also a soft, lisping 'sip' or 'tsip' contact call within flocks.

When they vocalize

Songs are primarily heard during the breeding season, from late spring through summer. Calls are given year-round, especially during foraging and migration.
