The red-headed woodpecker (Melanerpes erythrocephalus) is a mid-sized woodpecker found in temperate North America. Its breeding habitat is open country across southern Canada and the east-central United States. It is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species, having been down-listed from near threatened in 2018. [2]
The red-headed woodpecker should not be confused with the red-bellied woodpecker, which is similar in size but has a vibrant orange-red crown and nape; the red-bellied woodpecker is named for the pale reddish blush of its lower belly and has a distinctly patterned black and white back rather than the solid black one of the red-headed woodpecker.
The English naturalist Mark Catesby described and illustrated the red-headed woodpecker in his book The Natural History of Carolina, Florida and the Bahama Islands, which was published between 1729 and 1732. Catesby used the English name "The Red-headed Wood-pecker" and the Latin Picus capite toto rubro. [3] In 1758, the Swedish naturalist Carl Linnaeus updated his Systema Naturae to its tenth edition. He included the red-headed woodpecker and coined the binomial name Picus erythrocephalus, citing Catesby's book. [4] The specific epithet combines the Classical Greek ἐρυθρός, eruthros, meaning "red", and κεφαλή, kephalos meaning "headed". [5] The type locality is South Carolina. [6] The red-headed woodpecker is one of 24 species now placed in the genus Melanerpes , which was introduced by the English ornithologist William John Swainson in 1832 specifically to accommodate the red-headed woodpecker. [7] [8] The species is monotypic: no subspecies are recognized. [8]
Adults are distinctly tricolored, with a black back and tail, a white belly and rump, and a red head and neck. The wings are black with white secondary remiges. Adult males and females are identical in plumage. [9] Juveniles have similar markings, but their heads are grey. [9] Red-headed woodpeckers are entirely crimson above their shoulders.
These are mid-sized woodpeckers. Both sexes measure from 19 to 25 cm (7.5 to 9.8 in) in length, with a wingspan of 42.5 cm (16.7 in). [10] [11] They weigh from 56 to 97 g (2.0 to 3.4 oz), with an average of 76 g (2.7 oz). [12] Each wing measures 12.7–15 cm (5.0–5.9 in); the tail measures 6.6–8.5 cm (2.6–3.3 in), the bill measures 2.1–3 cm (0.83–1.18 in) and the tarsus measures 1.9–2.5 cm (0.75–0.98 in). [13] The maximum longevity in the wild is 9.9 years. [12]
This species gives a tchur-tchur call or a drum on its territory.
The red-headed woodpecker is omnivorous, eating insects, seeds, fruits, berries, nuts, and occasionally small rodents―even the eggs of other birds. [9] About two-thirds of its diet consists of plants. [9] Red-headed woodpeckers keep food caches. [14] This behavior is only seen in three other species of woodpeckers: the acorn woodpecker, the downy woodpecker, and the red-bellied woodpecker. [14] They have been known to stuff food in tree cavities, crevices, and under tree bark. [14] This keeps them well fed throughout the year. [14]
During the breeding season, a mature male red-headed woodpecker will establish a territory and begin calling and drumming to attract a mate. [15] Once the male has paired with a female, the relationship is believed to be mostly monogamous, and that they will remain paired for multiple breeding seasons. [16] [14] It is uncertain whether these relationships are truly monogamous as there have been reports of polygyny. [16]
When in an established territory, the parents become very territorial. [17] They have been known to destroy nests and eggs of other birds in their territory. [17] Females choose the location of their new nesting cavity, indicating their choice by tapping on a site. [15] This site could be a natural cavity, the wintering cavity used by the male, a cavity used the season before, a fence post, utility poles, or a dead tree. [15] [14] If the chosen site does not already have a nesting cavity, then both parents will drill out the nesting cavity, though the male will do most of the work. [15] [16] The chosen locations of these cavities are mostly in dead trees or utility poles between 2.45 and 24.5 m (8.0 and 80.4 ft) above the ground. [9] In early May, the female lays four to seven white eggs, which are incubated for two weeks. [9] The female incubates the eggs during the day and the male takes over at night. [15] After hatching, the young are cared for by both parents. [15] The young will stay in the nest until they are old enough to fledge, which is usually after 27 to 31 days. [15] After the first brood leaves the nest, the parents may start a second brood while still taking care of the fledglings from the first brood, though the first brood will not need as much care. [15] [16] This second brood may be raised in the same nesting cavity as the first, but it is common for the parents to make a fresh nesting cavity. [15] The fledglings are proficient flyers, and most are able to feed and care for themselves without too much help from the parents. [16] Most of the fledglings will disperse on their own within a couple of weeks, but if a fledgling is still in the territory after a few weeks the parents will chase them out to force them to disperse. [16] Two broods can be raised in a single nesting season. [9]
By late October, northern birds begin to migrate to the southern parts of the range to overwinter. Most will return to their breeding range by late April. [18] [19] Southern birds may not migrate.
The red-headed woodpecker was returned to a designation of least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered Species in 2018, having been downgraded to near threatened in 2004 after it appeared to have experienced a 65.5% decline in population over 40 years. [1] From 1966 to 2015 there was a greater than 1.5% annual population decline throughout the Mississippi and Ohio River valleys and central Florida. [20] Most of the decline in red-headed Woodpeckers can be attributed to loss of habitat and the competition for nesting cavities with the invasive European starling. [14] [21]
Increased habitat management is claimed to have helped in part in stabilizing its numbers, leading to its down-listing. [2]
The red-headed woodpecker was historically a common species in southern Canada and the east-central United States. Consistent long-term population declines have resulted in red-headed woodpecker's threatened status in Canada and several states in the US. Throughout most of its range, it inhabits areas that have been heavily altered by humans. Factors attributed to the red-headed woodpecker's decline include loss of overall habitat and, within habitats, loss of standing dead wood required for nest sites, [22] limitations in food supply, [23] and possible nest-site competition with other cavity nesters such as European starlings or red-bellied woodpeckers. [24] [25]
Of the 600 Canadian Important Bird Areas, only seven report the red-headed woodpecker in their area: Cabot Head, Ontario, on the Georgian Bay side of the tip of Bruce Peninsula; Carden Plain, Ontario, east of Lake Simcoe; Long Point Peninsula and Marshes, Ontario, along Lake Erie near London, Ontario; Point Abino, Ontario, on Lake Erie near Niagara Falls; Port Franks Forested Dunes, Ontario, northeast of Sarnia on Lake Huron; Kinosota/Leifur, Manitoba, on the northwest side of Lake Manitoba south of The Narrows and east of Riding Mountain National Park; and along the South Saskatchewan River from Empress, Alberta to Lancer Ferry in Saskatchewan. [26]
In 1996, the United States Postal Service issued a 2-cent postage stamp depicting a perched red-headed woodpecker. [27] The stamp was discontinued at some time thereafter, but re-issued in 1999 and remained available for purchase until 2006. [28]
The great spotted woodpecker is a medium-sized woodpecker with pied black and white plumage and a red patch on the lower belly. Males and young birds also have red markings on the neck or head. This species is found across the Palearctic including parts of North Africa. Across most of its range it is resident, but in the north some will migrate if the conifer cone crop fails. Some individuals have a tendency to wander, leading to the recolonisation of Ireland in the first decade of the 21st century and to vagrancy to North America. Great spotted woodpeckers chisel into trees to find food or excavate nest holes, and also drum for contact and territorial advertisement; like other woodpeckers, they have anatomical adaptations to manage the physical stresses from the hammering action. This species is similar to the Syrian woodpecker.
The wood duck or Carolina duck is a partially migratory species of perching duck found in North America. The male is one of the most colorful North American waterfowls.
The hooded merganser is a species of fish-eating duck in the subfamily Anatinae. It is the only extant species in the genus Lophodytes. The genus name derives from the Greek language: lophos meaning 'crest', and dutes meaning 'diver'. The bird is striking in appearance; both sexes have crests that they can raise or lower, and the breeding plumage of the male is handsomely patterned and coloured. The hooded merganser has a sawbill but is not classified as a typical merganser.
The common goldeneye or simply goldeneye is a medium-sized sea duck of the genus Bucephala, the goldeneyes. Its closest relative is the similar Barrow's goldeneye. The genus name is derived from the Ancient Greek boukephalos, a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin clangere.
The bufflehead is a small sea duck of the genus Bucephala, the goldeneyes. It breeds in Alaska and Canada and migrates in winter to southern North America. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Anas albeola.
The killdeer is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. The nominate subspecies breeds from southeastern Alaska and southern Canada to Mexico. It is seen year-round in the southern half of its breeding range; the subspecies C. v. ternominatus is resident in the West Indies, and C. v. peruvianus inhabits Peru and surrounding South American countries throughout the year. North American breeders winter from their resident range south to Central America, the West Indies, and the northernmost portions of South America. Despite their name, they are not known for killing deer.
The eastern bluebird is a small North American migratory thrush found in open woodlands, farmlands, and orchards.
The pileated woodpecker is a large, mostly black woodpecker native to North America. An insectivore, it inhabits deciduous forests in eastern North America, the Great Lakes, the boreal forests of Canada, and parts of the Pacific Coast. It is the largest confirmed extant woodpecker species in North America, with the possible exception of the ivory-billed woodpecker, which the U.S. Fish and Wildlife Service has proposed be reclassified as extinct. It is also the third largest species of woodpecker in the world, after the great slaty woodpecker and the black woodpecker. "Pileated" refers to the bird's prominent red crest, from the Latin pileatus meaning "capped".
The northern flicker or common flicker is a medium-sized bird of the woodpecker family. It is native to most of North America, parts of Central America, Cuba, and the Cayman Islands, and is one of the few woodpecker species that migrate. Over 100 common names for the northern flicker are known, including yellowhammer, clape, gaffer woodpecker, harry-wicket, heigh-ho, wake-up, walk-up, wick-up, yarrup, and gawker bird. Many of these names derive from attempts to imitate some of its calls. It is the state bird of Alabama.
The yellow-bellied sapsucker is a medium-sized woodpecker that breeds in Canada and the northeastern United States.
The downy woodpecker is a species of woodpecker, the smallest in North America. Length ranges from 14 to 18 cm. Downy woodpeckers primarily live in forested areas throughout the United States and Canada, with the exception of deserts in the southwest and the northern tundra. The bird nests in tree cavities and feeds primarily on insects, although it supplements its diet with seeds and berries. The downy woodpecker is very similar in appearance to the hairy woodpecker, although they are not closely related.
The acorn woodpecker is a medium-sized woodpecker with a length of around 20 cm (8 in), and an average weight of 85 g (3.0 oz). It is found across Central America, as well as North into the western United States and South into parts of Colombia.
The red-bellied woodpecker is a medium-sized woodpecker of the family Picidae. It breeds mainly in the eastern United States, ranging as far south as Florida and as far north as Canada. Though it has a vivid orange-red crown and nape it is not to be confused with the red-headed woodpecker, a separate species of woodpecker in the same genus with an entirely red head and neck that sports a solid black back and white belly. The red-bellied earns its name from the pale reddish tint on its lower underside.
The red-breasted sapsucker is a medium-sized woodpecker of the forests of the west coast of North America.
The eastern screech owl or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. This species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls. Although it often lives in close proximity to humans, the eastern screech owl frequently avoids detection due to its strictly nocturnal habits.
The red-cockaded woodpecker is a woodpecker endemic to the southeastern United States. It is a threatened species under the Endangered Species Act of 1973.
The Gila woodpecker is a medium-sized woodpecker of the desert regions of the southwestern United States and western Mexico. In the U.S., they range through southeastern California, southern Nevada, Arizona, and New Mexico.
Hoffmann's woodpecker is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found from Honduras south to Costa Rica.
Hildebrandt's starling is a species of starling in the family Sturnidae. It forms a superspecies with and has previously been included in the same species as Shelley's starling, a migratory species ranging from Ethiopia and Somalia to Kenya. Both of these species have also been combined into a superspecies with the chestnut-bellied starling of West Africa. It was originally placed in the now defunct genus Notauges. The species is named for Johann Maria Hildebrandt, a German collector who was the first European to obtain specimens.
The purple martin is a passerine bird in the swallow family Hirundinidae. It is the largest swallow in North America. Despite its name, the purple martin is not truly purple. The dark blackish-blue feathers have an iridescent sheen caused by the diffraction of incident light giving them a bright blue to navy blue or deep purple appearance. In some light, they may even appear green in color.
