Collared Grosbeak

Overview

The Collared Grosbeak inhabits coniferous and mixed montane forest along the Himalayas, often at similar elevations to other large Mycerobas grosbeaks. Males show a striking black head and collar against a bright yellow body, one of the more colorful large finches in its range. It typically forages in pairs or small groups high in the forest canopy, using its massive bill to process tough seeds.

Feather Identification

• Male head and upper mantle feathers form a solid black hood and collar, sharply demarcated from the bright yellow body
• Wings are black, lacking the bold white patch seen in the White-winged Grosbeak, a useful distinguishing feature
• Bill is large and conical, typical of the Mycerobas grosbeaks, suited for crushing seeds and cone material
• Females are duller, with a grayish-olive head and body rather than the sharp black-and-yellow contrast of males
• Tail feathers are black, unmarked
• Distinguished from White-winged and Spot-winged Grosbeaks by lacking a bold white or spotted wing patch, showing instead plain black wings against the yellow body

Plumage Notes

Adult males show a solid black head and collar against bright yellow body plumage with plain black wings. Females are duller, grayish-olive overall without the sharp head-and-body contrast. Juveniles resemble females. A single annual molt follows breeding.

Habitat & Range

Found along the Himalayas from Nepal eastward through Bhutan and adjacent regions, in coniferous and mixed montane forest at middle to high elevations. It shows altitudinal movement, descending somewhat in winter, but is not a long-distance migrant.

Behavior & Field Notes

Collared Grosbeaks forage in pairs or small groups in forest canopy, feeding on seeds, buds, and cone material using their heavy bill. Nests are built in coniferous trees. The call is a loud whistle or chattering note similar to related grosbeaks. It can be inconspicuous in dense canopy despite bright plumage, often detected first by voice.
