The orange-crowned warbler (Oreothlypis celata) is a small, nondescript songbird measuring 4.3-5.1 inches (11-13 cm) in length and weighing between 0.23-0.35 ounces (6.5-10 grams). This species is a member of the wood warbler family, Parulidae, and is found in various habitats including forests, woodlands, and shrublands throughout North America.
The orange-crowned warbler is primarily greenish-yellow with an inconspicuous, faint orange crown patch that is often difficult to see in the field. Distinguishing field marks include a thin, pointed bill, pale yellow underparts, and grayish-green wings with two white wing bars. Juveniles are similar in appearance to adults but lack the orange crown patch.
This species is primarily migratory, with breeding populations in the western and northern parts of North America and wintering populations in the southern and coastal regions of the United States, Mexico, and Central America. During migration, individuals can be found in a variety of habitats including gardens, parks, and riparian areas.
The orange-crowned warbler is a relatively inconspicuous species that often forages quietly in the understory of trees and shrubs, frequently gleaning insects from leaves and branches. These birds also consume berries and fruit during the winter months when insect populations are lower.
Overall, the orange-crowned warbler is a small, subtle species with a distinctive yellow-green coloration and faint orange crown patch. While difficult to observe, this species can be found throughout North America during migration and is an important member of the wood warbler family.
