Picoides is a genus of woodpeckers (family Picidae) that are native to Eurasia and North America, commonly known as three-toed woodpeckers.

Taxonomy

The genus Picoides was introduced by the French naturalist Bernard Germain de Lacépède in 1799. [2] The type species was subsequently designated as the Eurasian three-toed woodpecker (Picoides tridactylus) by the English zoologist George Robert Gray in 1840. [3] [4] The genus name combines the Latin Picus for a woodpecker and the Greek -oidēs meaning "resembling". [5] The genus Picoides formerly contained around 12 species. In 2015 a molecular phylogenetic analysis of nuclear and mitochondrial DNA sequences from pied woodpeckers found that three existing genera (Picoides, Veniliornis and Dendropicos ) were polyphyletic. After the resurrection of five monophyletic genera and the subsequent rearrangement in which most of the former members of Picoides were moved to Leuconotopicus and Dryobates , only three of the original species remained. [6] [7]

Description

The males of all three species have yellow on the crown, though this feature is also present in some other pied woodpeckers, namely brown-fronted and yellow-crowned. The remaining color pattern of the plumage, structural features, and life habits are very similar to related woodpeckers of the Dryobates and Leuconotopicus genera. [8] The foot of all three species show an extreme adaptation to arboreal living by lacking the first digit, or hallux. It has been pointed out however that various species of pied woodpecker are similar in having a short first digit. [8] Two species of woodpecker in genus Sasia (not closely related) also lack the first digit.

Habits

As opposed to genus Dryobates, the three species of Picoides obtain most (some 85%) of their insect prey by pecking live or dead wood. The hairy woodpecker (Leuconotopicus villosus) for instance, obtains only 45% of its food by pecking wood, 30% from the surface of trunks and 25% at other places. [8]

Species

The genus contains the following three species: [7]

Picinae containing the true woodpeckers is one of four subfamilies that make up the woodpecker family Picidae. True woodpeckers are found over much of the world, but do not occur in Madagascar or Australasia.

<span class="mw-page-title-main">Harrier (bird)</span> Genus of birds

A harrier is any of the several species of diurnal hawks sometimes placed in the subfamily Circinae of the bird of prey family Accipitridae. Harriers characteristically hunt by flying low over open ground, feeding on small mammals, reptiles, or birds. The young of the species are sometimes referred to as ring-tail harriers. They are distinctive with long wings, a long narrow tail, the slow and low flight over grasslands and skull peculiarities. The harriers are thought to have diversified with the expansion of grasslands and the emergence of C4 grasses about 6 to 8 million years ago during the Late Miocene and Pliocene.

<span class="mw-page-title-main">Lesser spotted woodpecker</span> Species of bird

The lesser spotted woodpecker is a member of the woodpecker family Picidae. It was formerly assigned to the genus Dendrocopos. Some taxonomic authorities continue to list the species there.

<span class="mw-page-title-main">Woodpecker</span> Family of birds (Picidae)

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.

<span class="mw-page-title-main">Hairy woodpecker</span> Species of bird

The hairy woodpecker is a medium-sized woodpecker that is found over a large area of North America. It is approximately 250 mm (9.8 in) in length with a 380 mm (15 in) wingspan. With an estimated population in 2020 of almost nine million individuals, the hairy woodpecker is listed by the IUCN as a species of least concern. Some nomenclature authorities, such as the eBird/Clements checklist, place this species in the genus Dryobates.

<span class="mw-page-title-main">Downy woodpecker</span> Species of woodpecker

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 yellow-billed kite is the Afrotropic counterpart of the black kite, of which it is most often considered a subspecies. However, DNA studies suggest that the yellow-billed kite differs significantly from black kites in the Eurasian clade, and should be considered as a separate, allopatric species.

<i>Campethera</i> Genus of birds

Campethera is a genus of bird in the family Picidae, or woodpeckers, that are native to sub-Saharan Africa. Most species are native to woodland and savanna rather than deep forest, and multiple species exhibit either arboreal or terrestrial foraging strategies. Its nearest relative is the monotypic genus Geocolaptes of southern Africa, which employs terrestrial foraging and breeding strategies. They are however not close relatives of similar-looking woodpeckers in the "Dendropicos clade".

<i>Dendropicos</i> Genus of birds

Dendropicos is a genus of woodpeckers in the family Picidae. They are small woodpeckers that are native to the sub-Saharan woodlands and forests.

<i>Sasia</i> Genus of birds

Sasia is a genus of birds in the woodpecker family Picidae, that are native to the Old World. They are very small, virtually tailless woodpeckers, with a crombec or nuthatch-like appearance and foraging habits. Their habitat is forest and secondary growth.
