Yellow-bellied sapsucker - Their breeding habitat is mixed forests in the Rocky Mountains and Great Basin areas of North America. They nest in a cavity in a dead tree. Other species which nest in tree cavities reuse nests formerly used by these birds.
Red-breasted sapsucker - Adults have a red head and upper chest; they have a white lower belly and rump. They are black on the back and wings with bars; they have a large white wing patch. Red-Breasted Sapsuckers nest in tree cavities. Northern birds migrate to the southern parts of the range; birds on the coast are often permanent residents. Like other sapsuckers, these birds drill holes in trees and eat the sap as well as insects attracted to it. They sometimes catch insects in flight; they also eat seeds and berries. These birds interbreed with the Red-naped Sapsucker or Yellow-bellied Sapsucker where their ranges overlap.
Williamson's sapsucker - Their breeding habitat is open forested areas, including conifers, in the western part of North America, from British Columbia to northern Mexico. They are permanent residents in some parts of their range; migrating birds form small flocks and may travel as far south as central Mexico.
Yellow-bellied sapsucker - The Yellow-bellied Sapsucker is part of the New World sapsucker genus Sphyrapicus, which is within the woodpecker family Picidae. The genus also includes the Red-naped Sapsucker, Red-breasted Sapsucker, and Williamson's Sapsucker.
