Sphyrapicus varius

The Yellow-bellied Sapsucker, *Sphyrapicus varius*, is a medium-sized migratory woodpecker renowned for its unique foraging strategy of drilling sap wells. Adults typically measure 7.5-8.3 inches (19-21 cm) in length, with a wingspan of 13.4-15.0 inches (34-38 cm) and weigh between 1.4-2.2 oz (40-62 g).

Found in deciduous or mixed coniferous-deciduous forests, preferring young to mature stands with ample birch, maple, or aspen. Breeds at higher elevations in its southern range and winters in a variety of forest types at lower elevations.

Diet

Primarily feeds on tree sap, particularly from birch, maple, and aspen, supplemented with insects attracted to the sap (especially ants), other arthropods gleaned from bark, and various fruits and berries.

Behavior

Yellow-bellied Sapsuckers are diurnal, spending their days methodically establishing and revisiting sap wells. Their distinctive foraging involves drilling horizontal rows of shallow holes in tree bark, then returning to lap up the exuded sap and any trapped insects. During the breeding season, m...

Range

The breeding range of the Yellow-bellied Sapsucker extends across the boreal forests of Canada and Alaska, through the Great Lakes region, northeastern United States, and south along the Appalachian Mountains to northern Georgia. During the fall, they undertake a lengthy migration, often moving o...
