Orange-crowned Warbler

The orange-crowned warbler has olive-grey upperparts, yellowish underparts with faint streaking and a thin pointed bill. It has a faint line over each eye and a faint broken eye ring. The orange patch on the crown is usually not visible. Females and immatures are duller in colour than males. Western birds are yellower than eastern birds. Orange-crowned warblers 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 song of is a trill, descending in pitch and volume. The call is a high chip.

Their breeding habitat is open shrubby areas across Canada, Alaska and the western United States. These birds migrate in the winter to the southern United States and south to Central America. Although they are quite common in the western United States, they are uncommon in the east.

They forage actively in low shrubs, flying from perch to perch, sometimes hovering. These birds eat insects, berries and nectar.
