Black-headed grosbeaks frequently sing from prominent perches. Both the male and female sing, but have different songs, and both are known to sing from the nest while incubating. When trying to court a female, males fly with their wings and tails spread. They forage in the foliage, on the ground, or in low vegetation and are prominent berry eaters.
The male blue grosbeak is deep blue, with both black and brown on its wings. The female is mostly brown. Both sexes are distinguished by their large, deep bill and double wing bars. These features, as well as the grosbeak's relatively larger size, distinguish this species from the indigo bunting. Length can range from 14 to 19 cm (5.5 to 7.5 in ...
Typically, fewer than 7% of grosbeak nests have cowbird eggs per one study. [38] Per the U.S. Bird Banding Laboratory, as of 1997, rose-breasted grosbeaks recovered when dead have largely collided with objects, including buildings and cars (17.2%) or had been shot (10%; mostly before 1960), 3.6% of the fatalities were caught by cats , 0.8% ...
The blue-black grosbeak construct little cup nests to lay their eggs in and normally have a clutch size of 2. [10] The breeding season of the blue-black grosbeak takes place during the spring and summer months, however the peak period of the breeding season differs slightly between populations located in different areas.

The evening and pine grosbeaks are finches, the same family as a goldfinch, whereas the rose-breasted grosbeak is in the cardinal family. The common name they share, “grosbeak,” was given long ...
The following is a list of grosbeak species, arranged in groups of closely related genera. These genera are more closely related to smaller-billed birds than to other grosbeaks. Exceptions are the three genera of "typical grosbeak finches", which form a group of closest living relatives and might thus be considered the "true" grosbeaks.
The black-backed grosbeak is approximately 22 cm (8.7 in) long and weighs 43.8 to 66.2 grams (1.54 to 2.34 oz). All of the subspecies except P. a. crissalis are very similar. The males' upperparts are black with a yellow shoulder patch; the closed wings show white patches.
The black-thighed grosbeak (Pheucticus tibialis) is a large seed-eating bird in the family Cardinalidae, which is endemic to the mountains of Costa Rica and western Panama. This species breeds from about 1,000 m (3,300 ft) altitude ( Pacific slope) or 1,500 m (4,900 ft) ( Caribbean slope) up to 2,600 m (8,500 ft) and is found in canopy ...
