Orange-crowned Warbler: Small warbler with olive-green upperparts and faintly streaked, yellow underparts. The head has inconspicuous orange crown, broken eye-ring, and faint eye-line. Though it lives and nests in dense foliage close to the ground, the male perches at the tops of tall trees to sing.
Range and Habitat
Orange-crowned Warbler: Breeds from Alaska east to Quebec and Labrador, and south to California, Arizona, and New Mexico. Spends winters from southern U.S. into tropics. Preferred habitats include forest edges, especially in low deciduous growth, burns, clearings, and thickets; often seen in riverside willows and scrub oak chaparral during migration.
The Orange-crowned Warbler is divided into four subspecies that differ in plumage color, size, and molt patterns.
It is likely that most, if not all of the early fall reports of Orange-crowned Warblers from the eastern United States and southeastern Canada are actually dull Tennessee Warblers.
The boreal-nesting form has one of the latest fall migrations of any warbler, not leaving its Canadian breeding grounds until late September or October.
A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
The Orange-crowned Warbler has a vast range that reaches up to 7,500,000 square kilometers. This bird can be found in the United States, Bahamas, Belize, Canada, Costa Rica, El Salvador, Guatemala, Mexico, Saint Pierre and Miquelon, and Turks and Caicos Islands. It inhabits subtropical and tropical forests as well as shrub lands. The global population of this bird is estimated to be around 76,000,000 individual birds. It is not believed that the population trends for this species will soon approach the minimum levels that could suggest a potential decline in population. Due to this, population trends for the Orange-crowned Warbler have a present evaluation level of Least Concern.
