The American three-toed woodpecker (Picoides dorsalis) is a medium-sized woodpecker (family Picidae), which is native to North America.
This woodpecker has a length of 21 cm (8.3 in), a wingspan of 38 cm (15 in), and an average weight of 55 g (1.9 oz); its maximum lifespan in the wild is 6 years. [3] It closely resembles the black-backed woodpecker, which is also three-toed. Until recently, it was considered to be the same species as the Eurasian three-toed woodpecker, P. tridactylus. [4] Adults are black on the head, wings and rump, and white from the throat to the belly; the flanks are white with black bars. The back is white with black bars and the tail is black with the white outer feathers barred with black. The adult male has a yellow cap.
The breeding habitat is coniferous forests across western Canada, Alaska and the western and extreme northeastern United States. It has also been seen in Michigan's upper peninsula, [5] and has been recorded breeding in the extreme north of Wisconsin and Minnesota on extremely rare occasions. [6] The female lays 3 to 7 but most often 4 eggs in a nest cavity in a dead conifer or sometimes a live tree or pole. The pair excavates a new nest each year. Three-toed woodpeckers rely on disturbed, old-growth forests and are strongly associated with active spruce beetle infestations, with beetle-infested trees being important for the woodpeckers and other species that depend on the cavities they excavate. [7]
This bird is normally a permanent resident, but northern birds may move south and birds at high elevations may move to lower levels in winter. Three-toed woodpeckers forage on conifers in search of wood-boring beetle larvae or other insects. They may also eat fruit and tree sap. These birds often move into areas with large numbers of insect-infested trees, often following a forest fire or flooding. This bird is likely to give way to the black-backed woodpecker where the two species compete for habitat.
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.
Woodpeckers are part of the bird family Picidae, which also includes the piculets, wrynecks and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specialises in exploiting cacti. Woodpeckers are known as the loudest birds of the forest.
The Eurasian treecreeper or common treecreeper is a small passerine bird also known in the British Isles, where it is the only living member of its genus, simply as treecreeper. It is similar to other treecreepers, and has a curved bill, patterned brown upperparts, whitish underparts, and long stiff tail feathers which help it creep up tree trunks. It can be most easily distinguished from the similar short-toed treecreeper, which shares much of its European range, by its different song.
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 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 black-backed woodpecker, also known as the Arctic three-toed woodpecker, is a medium-sized woodpecker inhabiting the forests of North America.
The Eurasian three-toed woodpecker is a medium-sized woodpecker that is found from northern Europe across northern Asia to Japan.
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 blush of its lower underside.
The red-naped sapsucker is a medium-sized North American woodpecker. Long thought to be a subspecies of the yellow-bellied sapsucker, it is now known to be a distinct species.
The brown creeper, also known as the American treecreeper, is a small songbird, the only North American member of the treecreeper family Certhiidae.
The boreal chickadee is a small passerine songbird in the tit family Paridae. It is found in the boreal forests of Alaska, Canada and the northern United States and remains within this range all year. This bird is known for its high pitched trill patterns used in communication with other birds and food storage habits in preparation for winter months.
The greater flameback, also known as the greater goldenback or large golden-backed woodpecker, is a woodpecker species. It occurs widely in the northern Indian subcontinent, eastwards to southern China, the Malay Peninsula, Sumatra, western and central Java and northeast Borneo.
The red-cockaded woodpecker is a woodpecker endemic to the southeastern United States. It is a federally endangered species under the Endangered Species Act of 1973.
The ladder-backed woodpecker is a North American woodpecker.
Nuttall's woodpecker is a species of woodpecker named after naturalist Thomas Nuttall in 1843. They are found in oak woodlands of California and are similar to the ladder-backed woodpecker in both genetics and appearance.
Strickland's woodpecker is a medium-sized species of woodpecker endemic to Mexico. The Arizona woodpecker was formerly considered the northern subspecies of this bird until the 42nd supplement of the American Ornithologists Union checklist, which officially split them into two separate species.
Williamson's sapsucker is a medium-sized woodpecker belonging to the genus Sphyrapicus (sapsuckers).
The Japanese pygmy woodpecker or pygmy woodpecker is a species of woodpecker. It is found in coniferous and deciduous forests in Russia, China, Korea and Japan. This species has also been placed in the genus Dendrocopos or Picoides. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
The Sind woodpecker is a species of bird in the family Picidae. It is native to Sindh province of Pakistan, India and southern Iran.
The white-tipped quetzal is a species of bird in the family Trogonidae found in Venezuela, Colombia, and Guyana. Two subspecies have been described. Pharomachrus fulgidus fulgidus is found in the mountains of northern Venezuela and Pharomachrus fulgidus festatus ranges through the Santa Marta mountains of northeast Colombia. Quetzals are iridescent and colourful birds found in forests, woodlands and humid highlands. The white-tipped quetzal has been a limited subject of research. Pharomachrus nests have been studied to analyse the effects of rainfall on breeding, however conclusions are based on single observations. On the IUCN Red list of threatened species, the white-tipped quetzal is listed as a species of least concern.
