Red-naped Sapsucker

Habitat

Red-naped Sapsuckers are the most common sapsucker in deciduous and streamside forests, especially in and around aspen, cottonwood, and willow. They also breed in mixed coniferous forests and will use open- and closed-canopy forests, burns, and clear-cuts, if there are some remaining standing trees.

Behavior

Sapsuckers get their name from their foraging strategy, which consists of drilling neat horizontal rows of holes in tree trunks and then returning to those holes later to feed on the running sap and the insects attracted to it. Unlike most woodpeckers, they forage in healthy trees and can actually kill a tree if they drill too many sap holes around its trunk, although this is quite uncommon. The persistent and conspicuous calls and drumming of Red-naped Sapsuckers are commonly heard in early spring.

Diet

Red-naped Sapsuckers are omnivores and feed on sap, insects, and fruits. During the nesting season they take more insects, and they feed insects to their young.

Nesting

Red-naped sapsuckers form monogamous pairs. They typically nest in healthy aspen trees or dead conifers. Both members of the pair excavate the nest cavity. Nest trees are often reused, but a new nest cavity is excavated most years. The nest is lined with woodchips from the excavation but no other lining. Both members of the pair incubate the 5 to 6 eggs for 12 to 13 days. Both feed the young, which leave the nest after 25 to 29 days and are dependent on the parents for about 10 days more. Red-naped Sapsuckers typically raise a single brood each year.

Migration Status

One of the most strongly migratory woodpeckers, the Red-naped Sapsucker travels as far south as central Mexico for the winter.

Conservation Status

Red-naped Sapsuckers are considered a keystone species, as many other species feed at the sap wells they drill. They were formerly lumped with Yellow-bellied Sapsuckers as one species, but were split off in 1985. The Breeding Bird Survey has identified a non-significant annual increase in Washington since 1966. In the Cascades, they sometimes hybridize with Red-breasted Sapsuckers.

When and Where to Find in Washington

A summer visitor to eastern Washington, the Red-naped Sapsucker is common from April through mid-August throughout the forested and riparian zones of eastern Washington. A few linger into early September. They are also rare breeders at high elevations just west of the Cascade crest. There are a few questionable winter records from western Washington, and any winter sighting of a Red-naped Sapsucker should be closely scrutinized because the apparent Red-naped Sapsucker may in fact be a Red-breasted Sapsucker hybrid.
