Orange-crowned warbler (Oreothlypis celata)

These birds are distinguished by their lack of wing bars, streaking on the underparts, strong face marking or bright colouring, resembling a fall Tennessee warbler and a black-throated blue warbler, both of which are also members of the New World warbler family. The orange patch on the crown is usually not visible. They have olive-grey upperparts, yellowish underparts with faint streaking and a thin pointed bill. They have a faint line over their eyes and a faint broken eye ring. Females and immatures are duller in colour than males. Western birds are yellower than eastern birds.
