Breeding birds have a yellow crown, pale face, and chestnut stripes along the sides.

Two pale wing bars; breeding males have bold dark facial markings.

Fall and young birds can have a lime-green back and crown, grayish face, and white eye-ring.

Breeding colors tell only half the story

In breeding plumage, look for a yellow crown above a strongly patterned face and white cheeks. Chestnut runs along the flanks, but its extent varies. Females generally have softer markings than males. Study where the colors occur, not just how much brown is visible. ^[1]

A different-looking autumn bird

After breeding, lime-green upperparts and a pale face with a neat white eye-ring replace the sharp spring pattern. Two wingbars and pale underparts remain useful clues. A bird with almost no chestnut can still belong to this species; compare the complete pattern with our Bay-breasted Warbler guide. ^[1]

A nest in the young growth

The female builds a cup of grasses, bark, and other plant fibers, fastening it with spider silk. Nests are usually below 6 feet, supported among small branches in a shrub or young tree. ^[2]

Clutches contain 3–5 eggs. Incubation takes about 11–12 days, and the young remain in the nest for roughly 10–11 days. Please stay on established routes rather than pushing through nesting thickets. ^[2]

Habitat has a time limit

A breeding patch may be suitable for fewer than ten years as young growth matures. A bird disappearing from one clearing can reflect changing vegetation, not simply a failure to return from migration. ^[2]

Different songs, different jobs

Males use songs with emphatic endings mainly in mate attraction. Songs without that final emphasis are more associated with defending a territory and interactions with other males. ^[3]

A familiar winter flock

Some individuals return to the same Central American winter areas and rejoin mixed-species feeding flocks from earlier years. Their annual routine links northern thickets with tropical woodland birds. ^[3]
