Cardinals and Allies
Pheucticus melanocephalus
The Black-headed Grosbeak is a chunky songbird of western North America, known for its robust, conical bill. Males display striking black, white, and cinnamon plumage, while females are more subtly patterned in browns and buffs. Their rich, warbling song is a familiar sound in woodlands during the breeding season.
Typical adult measurements.
Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Black head, black and white wings, and a bright cinnamon-orange breast and nape. Belly often shades to lemon yellow.
Brown back with dark streaking, brown wings with white bars, and a buffy to warm orange breast. Head is brown with a pale stripe above the eye.
Resemble females, with brown backs and streaked underparts, but young males may show hints of adult male coloration.
Both sexes have a large, thick, conical, grayish bill, darker on the upper half.
02 / A place in the world
This species favors deciduous and mixed woodlands, particularly in riparian areas, oak woodlands, and pine-oak forests. It can also be found in suburban areas with ample tree cover. During migration and winter, it uses various open wooded habitats.
Breeds across western North America, from southern British Columbia and Saskatchewan south through the western United States to central Mexico. Its non-breeding range is primarily in Mexico, along both the Pacific and Atlantic slopes, and into southern Baja California.
Black-headed Grosbeaks are migratory, with most populations moving south to Mexico for the winter. They tend to migrate later in spring and earlier in fall, with some individuals appearing away from breeding areas as early as mid-July.
03 / Listen a little closer
The song is a rich, warbling series of whistled notes, often compared to a tipsy robin or a clearer, richer version of a Western Tanager's song. Both males and females sing.
04 / The life behind the feathers
Their diet consists mainly of insects, seeds, and berries. They are one of the few bird species capable of consuming Monarch butterflies, which are toxic to most predators.
Forages primarily in shrubs and trees, gleaning food from foliage, but also searches for food on the ground and in low growth. Their heavy bill is adept at cracking open large seeds.
The female constructs a loose, cup-shaped nest of twigs, rootlets, and other plant materials, often so thin that eggs are visible from below. Nests are typically located in the outer limbs of trees or shrubs, usually 1-8 meters high. Both parents share incubation and feeding duties.
During the breeding season, males sing to defend their territory. Both sexes are known to sing. Outside of breeding, they may form small, loose flocks. They are diurnal and can be aggressive towards other grosbeaks of the same sex during breeding.
One more reason to pay attention
Black-headed Grosbeaks are among the few birds that can eat Monarch butterflies, despite the toxins the butterflies accumulate from milkweed.
Males do not achieve full adult breeding plumage until their second year.
The male Black-headed Grosbeak shares incubation and feeding duties equally with the female.
05 / An eye for the difference
Male Rose-breasted Grosbeaks have a black head and back with a prominent rose-red breast patch, contrasting with the Black-headed's cinnamon and black.
