Yellow-bellied Sapsucker
Learn to identify the Yellow-bellied Sapsucker by ear. Master the "drumming (tat-tat-tat...tap tap)" phrase and tell it apart from similar species.
What the Yellow-bellied Sapsucker sounds like
A medium-sized woodpecker with bold black-and-white patterning and touches of red. Both sexes have a black and white striped face and a long white wing stripe along the folded wing. Adult males have a bright red forehead and red throat, whereas females have a red forehead but a white (not red) throat. The chest is black, and the bird's flanks are light with extensive black mottling. Often there is a wash of pale yellow on the belly (hence the name, though this can be subtle). In flight, the wing shows a flashing white stripe. It perches upright on tree trunks, often remaining still for long periods near its sap wells.

Where you'll hear it
Deciduous and mixed forests, especially young forests or edges, often where birch, maple, aspen, or other sap-rich trees grow. Breeds in northern and montane forests of the eastern and central US and Canada, including aspen groves and beaver ponds with dead trees. In migration found in a variety of wooded habitats, even orchards and town parks. Winters in the southeastern US, West Indies, and Central America in woodlands, including pine forests, oak hammocks, and wooded swamps. Prefers areas with trees that can be tapped for sap (e.g., maples, hickories) and often near water. Common during migration in orchards or trees with high sugar content sap like pecan groves.
In spring, sapsuckers return to breeding woods and establish territories, often around a cluster of favored sap trees. They excavate nest cavities in decaying or soft wood (often aspen, birch, or pine). Both sexes work on the nest and raise the young, with eggs laid in late spring and chicks fledging by mid-summer. Throughout spring and summer, they maintain fresh sap wells to feed themselves, their mate, and later their young (supplementing with insects to feed nestlings). Come fall (September-October), they migrate out of northern areas. During migration and winter, they settle in suitable wooded habitats and drill new sap wells on different tree species (for instance, in the South they may tap oaks, pecans, or pines). They often remain on and defend a few productive "sap trees" throughout the winter. By late winter (February into March), as days lengthen, you may hear them begin territorial drumming even on wintering grounds. Hormonal changes prompt northward migration again in early spring, and the cycle repeats.
Similar species
Red-naped Sapsucker
Occurs in the West (Rocky Mountains westward); where ranges meet in the Great Plains or Canada, hybrids with Yellow-bellied can occur. Red-naped Sapsuckers look very similar but the male has red on the nape (back of the head) in addition to forehead and throat. Females have a red forehead and red chin patch often bordered by white, and usually some red on nape too. Yellow-bellieds lack any red on the back of the head (nape) – they have a white or light mottled nape instead. Also, Yellow-bellied has a completely white throat in female, whereas female Red-naped typically shows a mix of red and white in the throat. Range is usually the giveaway: if you are east of the Great Plains, it's almost certainly Yellow-bellied. If in the Rockies, lean toward Red-naped (or hybrid if in overlap zone).
Red-breasted Sapsucker
Another western relative, found on the Pacific Coast. Much more extensively red: adult Red-breasted Sapsuckers have the entire head and chest red, with only a small white slash on the side of the face and some white mottling on the sides. They do not have the black-and-white facial stripes that Yellow-bellied does. If you see a sapsucker with an entirely red head and chest in California or the Pacific Northwest, that's a Red-breasted. Juvenile Red-breasted are browner but still usually show some red coming in on the head without the stark black eye stripe of a Yellow-bellied.
Downy/Hairy Woodpecker
These spotted woodpeckers share the black-and-white pattern but have very different head markings. A Downy or Hairy Woodpecker male has a red patch on the hindcrown (back of head), not the forehead or throat, and females have no red at all. Instead, they have a bold white stripe down the back (sapsuckers have a mottled back with white spots and that long wing stripe, but not a solid white back). Downy/Hairy also have clean white underparts with some spots or barring only on the flanks, and they lack any yellow wash. Behavior is different too: Downy and Hairy peck and pry for insects and do not drill sap wells in neat rows. If you see an array of small wells in a tree or a woodpecker staying at one tree, gently tapping, it's likely a sapsucker, not a Downy/Hairy.
Northern Flicker (female)
Flickers are much larger with brown barred backs and spotted bellies, and a conspicuous white rump in flight. A female Yellow-shafted Flicker (in the East) has no red on the head at all (male has a black mustache mark). Flickers do sometimes create sap wells, but their appearance is quite distinct: a tan head, gray face, and big black crescent on the chest, plus they often feed on the ground. A sapsucker is smaller, more tree-bound, and has the striking head stripes with red. Flickers also flash yellow (or red in West) under wings in flight which sapsuckers do not.
