Habitat

Yellow-bellied Sapsuckers are found in a variety of woods containing deciduous or mixed coniferous-deciduous trees.

Diet

Yellow-bellied Sapsuckers eat insects, fruits, and tree sap, the latter being the source of the species’ unusual name.

Behavior

Sap is obtained by drilling rows of small holes in tree bark and returning later to feed on the oozing sap.

Range

Yellow-bellied Sapsuckers nest across much of southern Canada and the northeastern U.S., and winter in the southeastern U.S. and Mexico. The population may be stable, though it is not well monitored.

Wing Shape

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.

Fun Facts

Yellow-bellied Sapsuckers teach their young the sap drilling technique soon after fledging.

The Yellow-bellied Sapsucker is strongly migratory, with little overlap between summer and winter ranges.

Other species, including hummingbirds and warblers, will come to sapsucker holes for food.

Vocalizations

The most common call is a squealing, plaintive "meew".

Similar Species

  • Red-naped Sapsucker
    Male Red-naped Sapsuckers have more extensive red on the head and throat, and their red throat is not completely bordered by black. Female Red-naped Sapsuckers have red in the throat and can be mistaken for male Yellow-bellied Sapsuckers, though their ranges barely overlap only in southwestern Canada.
