Orange-Crowned Warbler

A plain, olive-gray warbler with only a faint orange crown patch rarely visible in the field, it favors shrubby thickets, forest edges, and streamside tangles rather than open canopy. Its song is a thin, weakly accelerating trill that often drops in pitch at the end, and it can be picked out by habit as it forages low, gleaning insects from leaves rather than flycatching. Migration in spring and fall, and winter in the southern and coastal parts of its range, are the most reliable times to see it, often mixed into flocks of other small songbirds.
