Description
This large songbird can be identified by its extra large, conical bill with a thick base. The black-headed Grosbeak also has a short, thick tail, making its appearance just a little less than graceful. The males have an appealing orange-cinnamon color. When in flight, you can spot bright yellow flashes beneath the wings of both sexes.

Feeding Habits
Black-headed Grosbeak's diet consists primarily of insects (60%, with a preference for beetles), spiders, and fruits, supplemented with seeds (mostly berries, oats, wheat, and various weed seeds). Their robust bills allow them to crush hard-bodied invertebrates and snails. They consume orchard fruits and are unique in tolerating monarch butterfly toxins.
Habitat
Black-headed Grosbeak are found in a variety of environments, typically favoring areas where different landscapes intersect, providing an assorted assembly of vegetation. They prefer regions with an abundance of large trees and well-developed understories, at altitudes where water is readily available. Ideal breeding habitats encompass riparian woodlands, scrubby forest edges, mountainous pine communities, and even modified habitats like parks and gardens. Black-headed Grosbeak eschew homogenous expanses like dense forests or dry grasslands. Wintering grounds mirror breeding preferences, situated in subtropical and tropical lowlands that are rich in plant variety and food sources.
Nest Behavior
The female black-headed Grosbeak constructs the nest over 3-4 days, focusing on material gathering initially and assembly later. The nest's loose build helps keep eggs cool. Both parents share egg incubation and chick rearing responsibilities.
Nest Characteristics
Black-headed Grosbeak's nest is a bulky structure located in deciduous trees or bushes up to 25 feet high, often near streams. It measures around 5-7 inches across, with a 3-4 inch wide inner cup lined with rootlets and hair. Its loose construction offers egg ventilation.

Migration Overview
Black-headed grosbeaks range from the Pacific Coast to the middle of the US Great Plains and from southwestern Canada to the mountains of Mexico. US and Canadian birds are highly migratory, wintering in Mexico. In the Great Plains, the range of the black-headed grosbeak and the rose-breasted grosbeak overlap and they have interbred somewhat. After the breeding season, they tend to seek out berry-rich areas. They migrate south early in the fall and return to the north late in the spring and have been known to do so in flocks.

Behavior
Black-headed Grosbeak primarily forage in the treetops and understory, adept at gleaning food and catching insects mid-flight with their robust bills. Daily routines include hopping on branches and at feeders, skillfully cracking open seeds and tough insects. Post-migration, pairs quickly form through elaborate nuptial flights by males who display their striking wing patterns while singing. Territorial defense involves both sexes, with singing and sometimes aggressive aerial grappling against intruders. Remarkably, black-headed Grosbeak shows tolerance towards certain non-threatening species near their nests but fiercely defends against potential predators. Both genders participate equally in nesting duties, including incubation and feeding their young, and may join loose flocks for migration.
