It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. The "Mycerobas" grosbeaks are a genus of finch in the family Fringillidae. Smaller birds (robins, jays, grosbeaks, chickadees, and so on) also abound. These genera are more closely related to smaller-billed birds than to other grosbeaks. Pine grosbeaks forage in trees and bushes. Pheucticus is a genus of grosbeaks containing six species. Other members of this family include cardinals, buntings, and other grosbeaks. Birds such as grosbeaks, flycatchers, western tanagers, and lazuli buntings are common in the area. Blue grosbeaks, dickcissels, and painted buntings can be seen during the summer months. Black-headed grosbeaks frequently sing from prominent perches. The winged fruits are eaten by squirrels, and by grosbeaks in the winter. The grosbeaks may utter a creaky groan in antagonistic interactions. These include rose-breasted grosbeaks, black-throated green warblers, ovenbirds, and great crested flycatchers. Cardinals and grosbeaks are a family of robust, seed-eating birds with strong bills.
