Species: O. ruficapilla
The Nashville warbler (Oreothlypis ruficapilla) is a small songbird in the New World warbler family, found in North and Central America. It breeds in parts of the northern and western United States and southern Canada, and migrates to winter in southern California and Texas, Mexico, and the north of Central America. It has a gray head and a green back, and its underparts are yellow and white.
At 12 cm (4.7 in), the Nashville warbler is a small warbler. Both male and female Nashville warblers have a gray head fading into a greenish back and wings, a white belly and a yellow throat and breast. They have a complete white eye ring, no wing bars, and a thin pointed black bill. Adult males have a rusty brown patch on their crown, which is usually hard to see and often covered by gray feathers. Males will raise it slightly when agitated. Females and immature birds have a duller olive-grey head, and less bold yellow on their throat. Males have wingspans of 5.8–6.6 cm (2.3–2.6 in), and females 5.3–6.1 centimetres (2.1–2.4 in).2 The Nashville warbler is closely related to Virginia’s warbler, Lucy’s warbler, and the Colima warbler, the four sharing generally similar plumage.
