Orange-crowned Warbler

About This Species

A drab, olive-yellow warbler with no obvious field marks, the Orange-crowned Warbler is named for its rarely-seen orange crown patch.

Hidden crown: The orange crown patch is almost never visible in the field, only occasionally shown during aggression or preening.
Variable plumage: Shows wide geographic variation, with Pacific birds being brighter yellow than interior populations.
Late migrant: Often one of the last warblers to leave in fall and among the earliest in spring.
Nectar feeding: Unlike most warblers, they sometimes visit flowers for nectar, especially in winter.
