Great Egg Harbor, New Jersey, USA

.

Hybrid with A. caudacuta has been described. Races mirabilis and †nigrescens have been considered to represent two separate species; latter was notably distinct, mirabilis much less so, but mirabilis and peninsulae differ vocally in having a song with a much less buzzy concluding trill than other races. Racial differences confused by individual variation and plumage dichromatism (buffy and grey morphs); proposed race pelonota (described from NE Florida) subsumed within macgillivraii. Seven extant subspecies recognized.
