Yellow-bellied Sapsucker

What do Yellow-bellied Sapsuckers look like?

The Yellow-bellied Sapsucker is a small woodpecker with mostly black and white plumage and red markings around the head and throat. They may have a yellowish wash to their belly and breast, but their common name really isn’t all that accurate.

They are primarily black above, with indistinct white barring on their back and bold white stripes along each wing. Their underparts are pale yellow or whitish with darker streaks and bars. The head is more distinctly marked with broad black and white stripes alternating from the crown to the throat.

Males and females are very similar but easily distinguished by the color of their throats. Females have a white throat, while males have a red throat, and both have a red forehead and a broad black band on the upper breast that forms a ring around the throat. Check out this guide for much more information on distinguishing between the sexes.

Juveniles are similar to adults but appear brownish and have much duller head markings. They do not have red plumage on the forehead or throat.

The Yellow-bellied Sapsucker is most easily confused with the Red-naped Sapsucker (S. nuchalis), but fortunately, their ranges are mostly separate.

How big are Yellow-bellied Sapsuckers?

Yellow-bellied Sapsuckers are small woodpeckers, larger than the Downy Woodpecker but smaller than the Red-bellied Woodpecker.

Length

Yellow-bellied Sapsuckers have a body length of approximately 7 to 9 inches (18 - 23 cm).

Weight

Adults have an average weight of about 1¾ ounces (50g), and there is little difference between the sexes.

Wingspan

Typical wingspans vary between 15½ and 17¾ inches (34 - 40 cm).

What sound does a Yellow-bellied Sapsucker make?

Yellow-bellied Sapsuckers vocalize and drum on resonant surfaces, particularly during the breeding season. Their typical call is a mewing ‘wheeer wheeer wheeer’ sound, although they also produce a ‘waa’ alarm call that can be heard at any time of the year.

Like many species in the woodpecker family, these birds drum on hollow tree trunks and other resonant surfaces to communicate. Yellow-bellied Sapsuckers drum relatively slowly and arrhythmically.

What is the habitat of a Yellow-bellied Sapsucker?

Yellow-bellied Sapsuckers are forest and woodland birds. They prefer deciduous and mixed forests that support their favorite food trees.

What is the range of a Yellow-bellied Sapsucker?

Yellow-bellied Sapsuckers are restricted to North America. They occur from Eastern Central Alaska across Canada to the Maritime Provinces and south through the eastern half of the Lower 48 states of the US. They also visit most of Mexico, Central America, and the Caribbean Islands.

How rare are Yellow-bellied Sapsuckers?

Yellow-bellied Woodpeckers are widespread birds and common in suitable habitats. However, they are rare in some states like Ohio and Missouri.

Where can you see Yellow-bellied Sapsuckers in the US?

Yellow-bellied Sapsuckers are very widespread east of the Rockies and the Great Plains. They breed in the Upper Midwest, Great Lakes region, and the Northeast down to West Virginia. Look out for overwintering birds across the Southeast in forests and woodlands from Texas to Florida and up the East Coast as far as Connecticut.

Where can you see Yellow-bellied Sapsuckers in Canada?

Yellow-bellied Sapsuckers are summer breeding visitors to every Canadian province and territory except Nunavut. They are mostly absent from the south of British Columbia, Alberta, and Saskatchewan and the north of Quebec.

Do Yellow-bellied Sapsuckers migrate?

Yellow-bellied Sapsuckers are highly migratory. These birds nest in the north of their range (mostly in Canada) during the spring and summer but retreat to the American Southeast, Mexico, the Caribbean, and Central America to enjoy the relatively mild southern winters.

Are Yellow-bellied Sapsuckers native to the US?

Yellow-bellied Sapsuckers are a native species in the United States. These highly migratory birds can be seen in different parts of the country during all months of the year.

• Look for neat rows of small holes on tree trunks, a telltale sign of sapsucker activity
• Listen for their distinctive 'mewing' call, which sounds cat-like
• In spring, watch for courtship drumming displays on resonant objects
• In eastern North America, check deciduous forests during migration seasons
• The Yellow-bellied Sapsucker is most easily confused with the Red-naped Sapsucker (S. nuchalis), but fortunately, their ranges are mostly separate.

What do Yellow-bellied Sapsuckers eat?

As their name suggests, Yellow-bellied Sapsuckers feed on the sap of various trees such as maples, aspens, and birches. They drill holes into the bark of these trees and wait for them to well up with the sugary fluid. Their diet is supplemented with insects attracted to the sap and various fruits.

What do Yellow-bellied Sapsucker chicks eat?

Their chicks are fed a diet of small insects, sometimes dipped in tree sap. Both parents feed the young.

Where do Yellow-bellied Sapsuckers nest?

Yellow-bellied Sapsuckers nest in the north of their range, primarily in Canada, but also in the American Northeast and parts of Alaska. The male drills a nest hole into a soft, fungus-infected limb of a deciduous tree but does not bring in any other material.

When do Yellow-bellied Sapsuckers nest?

Yellow-bellied Sapsuckers nest in late spring and summer, usually between May and July. The female will lay her eggs within days of her partner completing the nest, and both parents will work together to incubate them for ten to thirteen days. The young birds fledge the nest about four weeks later.

What do Yellow-bellied Sapsucker eggs look like?

Yellow-bellied Sapsuckers usually lay four to six plain white eggs, each measuring about 23 millimeters long and 17 millimeters across.

Do Yellow-bellied Sapsuckers mate for life?

Yellow-bellied Sapsuckers form monogamous pairs that remain together for the entire breeding season. They will usually reunite with the same partner each year or until one of the pair fails to return.

Are Yellow-bellied Sapsuckers aggressive?

Yellow-bellied Sapsuckers can be very protective over their sap supply and will chase away competition like large insects and hummingbirds. They are also territorial when nesting and may act aggressively toward other woodpeckers or members of their own species.

Where do Yellow-bellied Sapsuckers sleep at night?

Yellow-bellied Sapsuckers may sleep in their nest cavity during excavation, incubation, and brooding, but they sleep elsewhere for the rest of the year.

How long do Yellow-bellied Sapsuckers live?

Like most small birds, Yellow-bellied Sapsuckers typically live just a few years. The oldest individuals live 6 to 8 years.

What are the predators of Yellow-bellied Sapsuckers?

Yellow-bellied Sapsuckers are vulnerable to many predators from egg to adulthood. Small mammals like raccoons and birds of prey like Sharp-shinned and Cooper’s Hawks probably pose the greatest threats.

Are Yellow-bellied Sapsuckers protected?

Yellow-bellied Sapsuckers are protected by the Migratory Bird Treaty Act in the United States and Canada’s Migratory Birds Convention Act.

Are Yellow-bellied Sapsuckers endangered?

Yellow-bellied Sapsuckers are a widespread and common bird. Officially listed as a ‘Least Concern’ species on the IUCN Red List, they are not endangered.

While currently listed as Least Concern, Yellow-bellied Sapsuckers face threats from habitat loss due to deforestation and climate change. 

Conservation efforts focus on protecting mature deciduous forests and promoting sustainable forestry practices to maintain suitable breeding habitats.
