Sphyrapicus varius (Linnaeus, 1766) |
The yellow-bellied sapsucker (Sphyrapicus varius) is a medium-sized woodpecker that breeds in Canada and the north-northeastern United States.
The yellow-bellied sapsucker is one of four species in the genus Sphyrapicus. First described by Carl Linnaeus in 1766, it is monotypic across its sizable range. The genus name Sphyrapicus is a combination of the Greek words sphura, meaning "hammer" and pikos, meaning "woodpecker". The specific varius is Latin for "diverse".
The yellow-bellied sapsucker is a mid-sized woodpecker, measuring 18–22 cm (7.1–8.7 in) in length, 34–40 cm (13–16 in) in wingspan and weighing from 40–63 g (1.4–2.2 oz). Adults are black on the back and wings with white bars; they have a black head with white lines down the side and a red forehead and crown, a yellow breast and upper belly, a white lower belly and rump and a black tail with a white central bar. Adult males have a red throat; females have a white throat.
They drum and give a cat-like call in spring to declare ownership of territory.
The red-naped sapsucker is distinguished by having a red nape (back of the head). The hairy woodpecker has no red on the crown (front of the head) or throat and has blacker back. The downy woodpecker has same markings as the hairy woodpecker but is significantly smaller.
The breeding habitat of the yellow-bellied sapsucker 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.
