Orange-crowned Warbler

Overview

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.

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.
