Crimson-collared Grosbeak

The Crimson-collared Grosbeak is a distinctive forest songbird found in humid woodland and dense undergrowth from eastern Mexico into parts of Central America. Males show a dramatic combination of glossy black plumage broken by a broad crimson-red collar across the neck, extending onto the breast and rump, one of the more striking plumage patterns among Central American grosbeaks. Females present an entirely different but equally attractive pattern, olive-green overall with a yellow-orange collar and underparts replacing the male's crimson and black.

Adult male feathers are predominantly glossy black on the head, back, wings, and tail, broken by a broad band of crimson-red feathers forming a collar around the neck that extends down onto the breast and rump. The contrast between the black and crimson areas is sharp and well defined, without gradual blending. Females show olive-green body feathers with a corresponding band of yellow-orange across the neck and underparts, mirroring the male's pattern in position but entirely different in color, making the species easy to sex even at a glance once the collar is visible.

Adult males retain their black-and-crimson pattern year-round, with the crimson areas potentially appearing richer when feathers are fresh after molt. Adult females maintain the olive-and-yellow-orange pattern consistently through the year. Immatures generally resemble females, with young males gradually acquiring the black-and-crimson adult pattern through subsequent molts.

Crimson-collared Grosbeaks inhabit humid forest understory, edge, and dense thickets from eastern Mexico (including the lower Rio Grande valley of Texas as a rare visitor) south into parts of Central America. The species is generally resident within this range, favoring shaded, humid habitats over open country.

This species forages within dense understory and forest edge for seeds, fruit, and invertebrates, often remaining somewhat secretive within thick cover. The song is a rich, warbling series of notes typical of grosbeaks, often given from a concealed perch. Nests are cup-shaped, built within dense vegetation for cover. The bold collar pattern of both sexes, though different in color, makes for a memorable identification once the bird is seen well despite its tendency to stay within dense habitat.
