Brown Thrasher song and calls

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

Song

One of the most extensive and varied songs of North American birds. A long, complex series of musical phrases, typically delivered in pairs (each phrase repeated two or more times) before moving to a new phrase. Mimics other birds but often repeats phrases more consistently than a Northern Mockingbird. Phrases are rich, clear, and often include whistles, trills, and harsh notes. Can sing for extended periods.

Calls

Common calls include a sharp 'churr' or 'tchew' note, a harsh 'chuck' or 'smack' alarm call, and a soft 'whistle' contact call.

When they vocalize

Sings most frequently during the breeding season (spring and early summer), often from prominent perches. Calls are given year-round, especially when disturbed or communicating with a mate.
