About Leiothlypis celata (Say, 1822)
The orange-crowned warbler, with the scientific name Leiothlypis celata (Say, 1822), has olive-grey upperparts, yellowish underparts with faint streaking, and a thin pointed bill. It has a faint line above each eye and a faint broken eye ring. The orange patch on its crown is usually not visible. Females and immature individuals are duller in color than adult males. Populations of this species living in western regions are yellower than those found in eastern regions. Orange-crowned warblers can be distinguished by their lack of wing bars, lack of prominent streaking on the underparts, lack of strong facial markings, and lack of bright overall colouring. They resemble fall-plumaged Tennessee warblers and black-throated blue warblers, both of which are also members of the New World warbler family. The song of the orange-crowned warbler is a trill that descends in pitch and volume. Its call is a high chip. Their breeding habitat is open shrubby areas across Canada, Alaska, and the western United States. These birds migrate to the southern United States and as far south as Central America for the winter. While the species is quite common in the western United States, it is uncommon in the eastern United States. Orange-crowned warblers forage actively in low shrubs, flying from perch to perch and sometimes hovering while feeding. They eat insects, berries, and nectar.
