The yellow-bellied sapsucker, scientific name Sphyrapicus varius is a medium-sized woodpecker that breeds in Canada and the northeastern United States. Although its name feels like a cartoonist’s invention, the Yellow-bellied Sapsucker does exist. In this article, I am going to talk about Yellow-bellied Sapsucker call, range, behavior, diet, habitat, female, damage, sound, lifespan, vs downy woodpecker.
Yellow-bellied Sapsucker profile
This species is widespread within the north and east and is changed by shut kinfolk within the west. Quiet in winter, it turns into noisy in spring, with cat-like calls and staccato drumming.
Distribution and habitat
The yellow-bellied sapsucker is discovered throughout Canada, eastern Alaska, and the northeastern United States. These birds winter within the eastern United States, West Indies, and Central America. This species has occurred as a really uncommon vagrant to Ireland and Great Britain.
When this sapsucker is breeding, it’s usually present in deciduous and combined coniferous forests as much as 2,000 meters (6,600 ft) in the top. During the non-breeding season, alternatively, it often inhabits forests, however, the fringe of the forest, open woodland, and semi-open habitats are generally utilized.
It can be seen at bigger bushes in pastures, clearings, and suburban areas, along with the occasional look in palm groves. During this time, the yellow-bellied sapsucker ranges from sea level to elevations of 3,200 meters (10,500 ft), and even 3,400 meters (11,200 ft) in some areas, though the bird usually stays between altitudes of 900 and three,000 meters (3,000 and 9,800 ft).
Yellow-bellied Sapsucker Description
The yellow-bellied sapsucker has a size of around 19 to 21 centimeters (7.5 to 8.3 in), and a mean weight of 50.3 grams (1.77 oz), though this may range wherever from 35 to 62 grams (1.2 to 2.2 oz).
The yellow-bellied sapsucker has a wingspan that ranges from 13.4-15.8 in (34-40 cm). The brow is colored vivid red within the male (and really sometimes yellow), and a lighter shade of red within the feminine.
Sometimes, that is the one place on the pinnacle a feminine could have red coloration, if it has any in any respect, as the feminine hardly ever has a black head with just a few buff spots. The crown is bordered black, and is often red, and is typically combined with black within the feminine.
There is a white stripe, beginning above the attention, that extends and widens to the nape, being damaged up by a skinny black line on the hindneck.
There is a broad black stripe going by the ear-coverts and down to the facet of the neck. Below this black stripe is a white stripe that goes from the nasal tufts to the facet of the breast. The throat and chin can be utilized to distinguish between the sexes, as they’re white within the feminine and red within the male.
The mantle of this sapsucker is white, and there are irregular black bars that stretch from it to the rump. The lower rump is white, and the uppertail-coverts are white with some black webbing. The wing coverts are black, and there’s a white panel on the medians and central greater-wing coverts.
The flight feathers are black with white suggestions. The innermost tertials are white and black. The underwing is barred greyish and white. The uppertail is black, with some white webbing and white suggestions generally being current on the outer feathers.
The underparts, excluding the pale breast and above, are tinged yellow, transitioning to a whiter color within the decrease area of them. The facet of the breast right down to the undertail coverts have black arrowhead-shaped markings.
The chisel-tipped bill is comparatively brief and straight, with a slate to blackish color. The legs are blue-grey to green-grey in color, and the irides are a deep brown.
The juvenile is a darkish olive-brown color total, with a buff-striped head and a streaked crown. The throat is often white, though, within the male, there could also be some red.
The upperparts are usually a mottled pale and blackish color. The breast is scaly, and the central part of the stomach is a really pale yellow color. The tail is barred more than within the grownup.
Yellow-bellied Sapsucker Color Pattern
Yellow-bellied Sapsuckers are principally black and white with boldly patterned faces. Both sexes have red foreheads, and males even have red throats. Look for a long white stripe alongside the folded wing. Bold black-and-white stripes curve from the face towards a black chest protect and white or yellowish underparts.
Yellow-bellied Sapsucker Vocalizations, Call and communication
The yellow-bellied sapsucker, often the male, makes use of a long-distance nasal “neaaah, “owee-owee,” “wee-wee-wee-wee,” or “kwee-urk” at the start of breeding to attract its mate to various places within its territory.
When birds of a family group meet, they exchange low “week week”, “wurp wurp”, or similar low calls. A scratchy “quirk quirk” is given when pairs meet at the breeding territory. When it is alarmed, this bird will utter a soft mew call, getting louder and hoarser as the threat increases. During a conflict, it produces a shrill “quarr”.
This sapsucker drums on supplies that reverberate loudly, with drums beginning as fast bursts however turning into more drawn out as time goes on. The bursts often final between one and a half and 5 seconds.
These drums have been beforehand thought for use to point the standard of a nesting or feeding website, however, it’s seemingly that they’re used as a type of long-distance communication. Trees chosen to drum on are useless, and thus aren’t these used for feeding or nesting.
Yellow-bellied Sapsucker Feeding
The yellow-bellied sapsucker often forages by itself, though it generally joins small teams within the winter, and sometimes mixes into flocks of insectivores within the winter.
Arthropods, tree sap, fruits, and nuts compose nearly all of the yellow-bellied sapsucker’s weight loss plan. It additionally takes bast and cambium from bushes.
Berries are sometimes eaten, and within the Northern Hemisphere spring, buds are eaten. Arthropod prey is often within the type of Lepidoptera, Odonata, or each the younger and adults of beetles and ants.
During the nesting season, bugs comprise about half the weight loss plan of the adults. During the late Northern Hemisphere summer and all through the identical hemisphere’s autumn, the sap is the first meals of selection.
Cambium is taken all through the year, though it’s primarily eaten through the Northern Hemisphere winter and spring. The fruit is principally eaten from October to February.
The chicks are fed by each sex. The main meal is bugs that are sometimes coated in tree sap before eaten by the chick. The size of those bugs varies by the age of the chicks, with youthful chicks being fed smaller bugs.
The chicks beg for meals by vocalizations that may be heard 100 meters (330 ft) away or more, seemingly stimulating the adults to catch more meals. These vocalizations are often executed by the hungriest chick, with the opposite becoming a member of in solely when the parent is on the nest.
Because of this, the hungriest chick will get fed first. When the chick leaves the nest, it depends on each insect from its dad and mom and sap from the holes they drill.
In the breeding season, this sapsucker prefers to take sap from the bushes Betula papyrifera, Acer rubrum, Amelanchier, and Populus grandidentata.
Other bushes of the genera Populus, Betula, and Acer are additionally used, along with deciduous bushes of the genera Salix, Carya, Alnus, and coniferous bushes of the genera Pinus, Picea, and Abies. In the Northern Hemisphere winter and spring, often feeds on conifers, whereas in its autumn, feeding on rough-barked bushes is most typical.
Yellow-bellied Sapsucker Breeding
Yellow-bellied sapsuckers nest in a big cavity excavated in a stay deciduous tree, usually selecting one which has rotten heartwood; an appropriate tree could also be reused. It particularly prefers Populus tremuloides bushes which have conks of Fomes fomentarius var. populinus.
Other bushes within the genus Populus and people within the genus Betula are standard selections. An examination in northern Canada discovered that the yellow-bellied sapsucker nested in bushes with a diameter at breast top (DBH) ranging wherever from 22 to 79 centimeters (8.7 to 31.1 in), with a mean DBH of about 35 centimeters (14 in) for nestling bushes, in comparison with the common DBH within the space of about 41 centimeters (16 in).
An examination within the northeastern United States, nonetheless, concluded that this sapsucker has a search picture for bushes with the best attributes; considered one of these attributes was having a DBH of 20 to 25 centimeters (7.9 to 9.8 in). The examination additionally concluded that deviance from this search picture might be brought on by the rarity of the bushes that fulfill such standards.
This bird is monogamous, and nests in pairs, with each sex, working to make the nest. Excavation of the cavity is finished principally by the male, with excavation often being executed constantly for 15 to 30 minutes at a time.
Excavation takes about 15 to 28 days, though additional hollowing out is finished by each sex after the chicks hatch. The cavity itself is wherever from 2 to 20 meters (6.6 to 65.6 ft) above the floor, though it’s often discovered between heights of three and 14 meters (9.8 and 45.9 ft).
This sapsucker can be territorial, with territories having a radius starting from about 46 to 137 meters (150 to 450 ft) away from the nest. Territories in much less wooded areas are sometimes bigger than these in areas closely wooded.
The male often arrives on the nesting grounds about one week before the feminine. The sapsucker arrives early within the Northern Hemisphere spring, usually before heavy snowfall has stopped. The precise breeding season is from April to July.
Yellow-bellied Sapsucker Nest
During nest excavation, a bird could carry out a courtship flight. This flight consists of the sapsucker quickly flapping its wings beneath its partner. It appears to construct the pair bond and assist enhance attachment to the nest.
Members of a pair additionally carry out dance the place they bob their heads and repeatedly opening their wings midway. They even have the courtship ritual of touching their payments collectively.
Courtship moreover consists of giving “quirk” notes and, from a distance, “kwee-urk” calls. Copulation can include the feminine perching perpendicularly on a department, the male mounting her back, regularly falling backward and to the left till he’s the wrong way up and at a right angle to the feminine.
Yellow-bellied Sapsucker Eggs
This bird lays a clutch of 4 to seven eggs, with clutches being bigger for birds within the northern part of the range. The eggs themselves are white and spotless, measuring around 24 by 17 millimeters (0.94 by 0.67 in).
During egg-laying, the feminine is dominant, generally driving the male away from the nest. Both sexes incubate the eggs through the 10 to 13-day incubation interval, with the male often doing so over the night time. Sapsuckers are stressed however quiet throughout this time, and the eggs are left uncovered about 16% of the time through the incubation interval.
Weather often doesn’t have an effect on incubation, though, on significantly sizzling days, the dad and mom incubate the eggs for much less time. When the chicks hatch, they’re brooded for 8 to 10 days by each sex.
Nests with fewer younger are brooded more, presumably as a result of smaller broods lose warmth sooner. After 25 to 29 days, the younger go away the nest for this first time and turn into impartial after about two weeks.
Status and conservation
The yellow-bellied sapsucker is taken into account to be the least concern by the IUCN, regardless that it has lowering inhabitants. This is due to its giant range of about 7,830,000 sq. kilometers (3,020,000 sq mi).
In addition, it has big inhabitants, is widespread in its range, though it isn’t simply seen when not breeding. It has a low genetic range; about half of that of most birds.
In the United States, yellow-bellied sapsuckers are listed and guarded beneath the Migratory Bird Treaty Act, making taking, killing, or possessing it unlawful without a permit.
Yellow-bellied Sapsucker Identification
Look for Yellow-bellied Sapsuckers in younger deciduous forests. To discover a sapsucker’s territory, preserve an eye fixed out for his or her distinctive, neatly organized rows of sapwells.
You’ll most certainly discover them tending to their sapwells, however, you may also see them perched on the suggestions of tree branches when attempting to find bugs. In spring, pay attention to his or her mewing calls and their distinctive irregular drumming.
They cling immobile to bushes whereas calling, so if you happen to hear a Yellow-bellied Sapsucker, look intently on the bushes around you for his or her sharply contrasting black-and-white face stripes and the bright-red patches on their heads.

Yellow-bellied Sapsucker Facts
- The Yellow-bellied Sapsucker makes two sorts of holes in bushes to reap sap. Round holes lengthen deep within the tree and aren’t enlarged. The sapsucker inserts its bill into the opening to probe for sap. Rectangular holes are shallower and should be maintained frequently for the sap to move. The sapsucker licks the sap from these holes and eats the cambium of the tree too. New holes often are made in a line with old holes, or in a brand new line above the old.
- The sapwells made by Yellow-bellied Sapsuckers appeal to hummingbirds, which additionally feed off the sap flowing from the tree. In some components of Canada, Ruby-throated Hummingbirds rely a lot on sapwells that they time their spring migration with the arrival of sapsuckers. Other birds, in addition to bats and porcupines, additionally go to sapsucker sapwells.
- Yellow-bellied Sapsuckers have been discovered drilling sapwells in more than 1,000 species of bushes and woody vegetation, although they have a powerful desire for birches and maples.
- The Yellow-bellied Sapsucker continuously makes use of human-produced supplies to assist in its territorial drumming. Street indicators and metal chimney flashing amplify the irregular tapping of a territorial sapsucker. The sapsucker appears to endure no in poor health results of whacking its bill on metal, and a bird will return to a favorite signal day after day to pound out its Morse code-like message.
- The Yellow-bellied Sapsucker is the one woodpecker in eastern North America that’s utterly migratory. Although just a few people stay all through a lot of the winter within the southern part of the breeding range, most head farther south, going as far south as Panama. Females are inclined to migrate farther south than do males.
- The oldest identified Yellow-bellied Sapsucker was a male, and a minimum of 7 years, 9 months old. It was banned in New Jersey and located 6 years later in South Carolina. Learn more about western sandpiper.
