Yellow-browed Bunting

Overview

The Yellow-browed Bunting breeds in Siberian taiga and winters mainly in eastern China. Its head pattern resembles that of several related striped-crown buntings, but the yellow wash at the front of the supercilium is a useful distinguishing feature.

It is a scarce and localized species compared with some of its more widespread relatives.

Feather Identification

• Supercilium: pale yellow near the bill, fading to whitish toward the back of the head.
• Crown: dark stripes bordering a paler central stripe, similar to related striped-crown buntings.
• Underparts: white with fine dark streaking along the flanks.
• Wing bars: two narrow white wing bars visible on folded wings.

The yellow-tinged front portion of the supercilium, combined with white wing bars, separates this species from the whiter-browed Tristram's Bunting.

Plumage Notes

Breeding and non-breeding plumages are fairly similar in this species, with the yellow supercilium tint present year-round, though it may appear slightly duller outside the breeding season.

Females resemble males closely, and juveniles show more diffuse streaking with a less distinct supercilium color. A single annual molt follows breeding.

Habitat & Range

This bunting breeds in taiga forest and scrub across Siberia, wintering primarily in eastern China, with occasional records farther afield during migration.

It is considered a scarce migrant across much of its range, often found in small numbers at forest edges and scrubby habitat during passage.

Behavior & Field Notes

Yellow-browed Buntings forage on the ground and in low vegetation for seeds and insects, often in small groups or mixed with other buntings during migration.

The nest is built on or near the ground in breeding habitat. The song is a simple, brief series of notes. The yellow-tinged supercilium is the most useful feature for separating this species from similarly striped relatives in the field.
