Oreothlypis celata
adult
The Orange-crowned Warbler’s orange crown patch is hard to see and not a useful field character. The body plumage shows subtle geographical variation across its breeding range, with the west coast subspecies being brighter yellow than the duller yellow-green subspecies found across northern North America. The sexes are dissimilar. Given the regional variation, adult males are yellow-green, subtly darker above than below, with faint streaks on the underparts and a yellow-buff undertail (cf. immature Tennessee Warbler. The face shows a gray tint, an indistinct pale eyering, and a pale supercilium. Adult females and immatures are similar to males but grayer overall and less colorful.
The Orange-crowned Warbler is present as a breeding species mainly from May to September. It spends the rest of the year in Central America.
