Blackburnian Warbler

The Blackburnian Warbler is widely regarded as one of the most stunning songbirds in North America, with breeding males showing an almost incandescent orange throat and face pattern that seems to glow against black head markings. The crown, cheek patch, and back are black, boldly set off by the blazing orange throat, orange-tinged eyebrow, and a black triangular patch on the cheek.

The underparts are pale yellow-orange fading to white, streaked with black along the flanks, and the black wings show a bold white patch. Females and immatures show a much more muted version of the pattern, with yellow-orange replacing the male's fiery orange, but retain the same overall face pattern that makes the species distinctive.

Key Field Marks

• Breeding male: blazing orange throat and face pattern set against black crown, cheek triangle, and back
• Bold white wing patch
• Black streaking on pale yellowish flanks
• Female/immature: duller yellow-orange version of the same head pattern
• Fine, sharp black bill

Similar Species

No other North American warbler shows the same combination of black head markings and fiery orange throat; breeding males are unmistakable. Female and fall birds can be confused with other yellow-faced warblers, but the pattern of dark cheek patch bordered by pale eyebrow and throat, plus overall structure, usually allows identification with care.

Habitat

Blackburnian Warblers breed in mature coniferous and mixed forests, with a strong preference for tall spruce, fir, and hemlock, foraging and nesting mainly high in the canopy.

Range

This species breeds across the boreal forest of Canada, the northeastern United States, and south through the Appalachian Mountains at higher elevations. It winters primarily in the Andes and forested foothills of South America.

Migration

Blackburnian Warblers are long-distance Neotropical migrants, traveling to South America for winter, one of the longer migrations among the wood-warblers.

Behavior

This species forages high in the treetops, often at the very tips of tall conifers, making it a challenging bird to observe well despite its brilliant coloring.

Voice

The song is a very high-pitched, thin series of notes accelerating into an almost inaudibly high trill, often described as 'teeser-teeser-teeser-tsee.' The call is a sharp, thin 'chip.'

Feeding

It gleans insects and spiders from needles and twigs high in the canopy, occasionally sallying briefly to catch flying insects.

Nesting & Breeding

The female builds a small cup nest of twigs and lichen, typically placed far out on a horizontal conifer branch high above the ground. She lays 3-5 eggs, and nests are notoriously difficult to find due to their height and canopy concealment.
