Which bird species has the largest known vocal repertoire of over 1,100 song types?

The bird species known for a vocal repertoire of more than 1,100 song types is the brown thrasher. This North American songbird produces an extraordinary variety of phrases, often mixing original patterns with imitations of other birds.

Male brown thrashers use song during courtship and territorial behavior. Studies have documented repertoires exceeding 1,100 song types, while some descriptions count more than 2,000 or even 3,000 individual phrases, depending on how researchers define and classify a “song.” The bird commonly repeats a phrase twice before moving to another, giving its singing a distinctive paired rhythm.

The northern mockingbird is the usual source of confusion because it is also a celebrated mimic and can copy many birds, frogs, and other sounds. The brown thrasher’s claim is generally framed as the largest documented repertoire among North American songbirds, rather than an absolute record for every bird worldwide. Superb lyrebirds are remarkable mimics too, but the over-1,100 song-type statistic is most closely associated with the brown thrasher.
