small, active, insect-eating bird
White wing bars
Thin, pointed bill
White spots visible on underside of tail
Adult male alternate:
Brown crown, upper breast and sides
Buffy patch on side of neck
Female in alternate plumage similar to male but duller with reduced rust on sides
Basic and immature:
Greenish crown, nape and back with thin black streaks
Breast somewhat paler than upperparts
Creamy belly and undertail coverts
Some rust may be present on sides
In alternate plumage, the only other warbler with rusty sides is the
chestnut-sided warbler but it has a yellow crown and white throat.
Basic (fall) and immature plumages are very dull and most similar to
blackpoll and pine warblers. The blackpoll warbler has yellow legs,
white undertail coverts, and a streakier breast. Pine warbler lacks
black streaks on the back and is often yellower on the throat and
breast. Often, bay-breasted warblers retain a trace of rusty sides
in the fall.
