SPECIES RECOGNITION IN A VOCAL MIMIC: REPETITION PATTERN NOT THE ONLY CUE USED BY NORTHERNMOCKINGBIRDS IN DISCRIMINATING SONGS OF CONSPECIFICS AND BROWN THRASHERS

Vocal mimics that produce large repertoires of song types, such as in the Mimidae, have uniquechallenges discriminating songs of conspecifics from those of other mimids in areas where these species cooccur.We investigated cues used by Northern Mockingbirds (Mimus polyglottos) in discriminating their songsfrom songs of a sympatric mimid, the Brown Thrasher (Toxostoma rufum).
