Adult males have a red throat; females have a white throat.

Distribution and Habitat
Their breeding habitat is forested areas across Canada, eastern Alaska and the northeastern United States. They prefer young, mainly deciduous forests. There is also a disjunct population found in high elevations of the Appalachian Mountains in Virginia, Tennessee, and North Carolina.
Ecology and Behavior
Like other sapsuckers, these birds drill holes in trees and eat the sap and insects drawn to it. They may also pick insects from tree trunks or catch them in flight. They also eat fruit and berries.
Yellow-bellied Sapsuckers nest in a large cavity excavated in a deciduous tree, often choosing one weakened by disease; the same site may be used for several years.
They will mate with the same partner from year to year, as long as both birds survive. They sometimes hybridize with Red-naped Sapsuckers or Red-breasted Sapsuckers where their breeding ranges overlap.
Wintering and Migration
These birds migrate to the southeastern United States, West Indies and Central America, leaving their summer range. This species has occurred as a very rare vagrant to Ireland and Great Britain.
