Nashville Warbler
Oreothlypis ruficapilla
The Nashville Warbler (Oreothlypis ruficapilla) is a small songbird in the New World warbler family.
Nashville Warblers have olive-brown upperparts, a white belly and a yellow throat and breast; they have a white eye ring, no wing bars and a thin pointed bill. Adult males have a grey head with a rusty crown patch ; females and immature birds have a duller olive-grey head. The Nashville Warbler is closely related to Virginia's Warbler, Lucy's Warbler and Colima Warbler, the four sharing generally similar plumage.
Two discrete populations exist. The nominate subspecies, ''O. r. ruficapilla'', breeds in northeastern North America. The other subspecies, ''O. r. ridgwayi'', known as the Calaveras Warbler, nests in western North America. The latter differs from the former in its relatively duller plumage and more persistent tail movements.
