The subject of the study and handsome Mockingbird, whose songs have fooled many a beginner birder, comes up because of this nifty story about one from Attack Machine. They are remarkable mimics.
The Mockingbird, (Mimus polyglottos), once a Southern bird, is now found across the US and into southern Canada. His repertoire of over 200 songs - copies of the songs and calls of other species - caused him once to be caged as the American nightingale.
The family of Mimic Thrushes also includes thrashers and the catbird. All are fond of tangles, shrubs and borders.
Many of our Mockingbirds in New England overwinter here, and occasionally visit the bird feeder, but they do not seem to like seeds very much.
