Picoides Tridactylus MWNH 1227
''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. The type species was subsequently designated as the Eurasian three-toed woodpecker (''Picoides tridactylus'') by the English zoologist George Robert Gray in 1840. The genus name combines the Latin ''Picus'' for a woodpecker and the Greek ''-oidēs'' meaning "resembling". 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 t ...

Eurasian Three-toed Woodpecker
The Eurasian three-toed woodpecker (''Picoides tridactylus'') is a medium-sized woodpecker that is found from northern Europe across northern Asia to Japan. Taxonomy The Eurasian three-toed woodpecker was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his '' Systema Naturae''. He coined the binomial name ''Picus tridactylus''. The type locality is Sweden. The specific epithet is from the Ancient Greek ''tridaktulos'' meaning "three-toed" (''tri-'' is "three-" and ''daktulos'' is toe). The species is now placed in the genus '' Picoides'' that was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The Eurasian three-toed woodpecker was formerly considered conspecific with the American three-toed woodpecker (''Picoides dorsalis''). Eight subspecies are recognised: * ''P. t. tridactylus'' (Linnaeus, 1758) – northern Europe to the southern Ural Mountains and to south-eastern Siberia and north-eastern China * ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Black-backed Woodpecker
The black-backed woodpecker (''Picoides arcticus''), also known as the Arctic three-toed woodpecker, is a medium-sized woodpecker ( long) inhabiting the forests of North America. Taxonomy The black-backed woodpecker was described and illustrated by the English naturalist William John Swainson in 1832 from a specimen collected near the source of the Athabasca River on the eastern slopes of the Rocky Mountains in Alberta, Canada. He coined the binomial name ''Picus arcticus''. The specific epithet ''arcticus'' is the Latin word for "northern" or "arctic". The black-backed woodpecker is now placed in the genus ''Picoides'' was erected by the French naturalist Bernard Germain de Lacépède in 1799. The species is monotypic: no subspecies are recognised. Description The plumage of adults is black on the head, back, wings and rump. They are white from the throat to the belly; the flanks are white with black bars. Their tail is black with white outer feathers. There is an elemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hairy Woodpecker
The hairy woodpecker (''Leuconotopicus villosus'') is a medium-sized woodpecker that is found over a large area of North America. It is approximately in length with a 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''. Taxonomy The hairy woodpecker was described and illustrated with a hand-coloured plate by the English naturalist Mark Catesby in his ''The Natural History of Carolina, Florida and the Bahama Islands'' which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition, he included the downy woodpecker, coined the binomial name ''Picus villosus'' and cited Catesby's book. The specific epithet ''villosus'' is the Latin word for "hairy". Linnaeus specified the type lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sasia
__NOTOC__ ''Sasia'' is a genus of birds in the 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. All three species have a flesh Eye-ring, orbital ring and a rounded (in cross-section) upper mandible. The African species has only eight Flight feather#Rectrices, rectrices but four toes in a Bird feet and legs#Toe arrangements, zygodactyl arrangement (a weak first digit), while the two Asian species have ten rectrices and only three toes (absent first digit, or hallux). In addition the African species differs from the Asian species in plumage colour of the adult, but not at all in plumage pattern, body anatomy or in habits. Their relationship with genus ''Picumnus (bird), Picumnus'' has not been established, and the Picumninae may be either Monophyly, monophyletic or Paraphyly, paraphyletic.Winkler et al., 2014 Species It ...

Brown-fronted Woodpecker
The brown-fronted woodpecker (''Dendrocoptes auriceps'') is a species of bird in the family Picidae. It ranges across the northern regions of the Indian subcontinent, primarily the lower-to-middle altitudes of the Himalayas. It is found in Afghanistan, India, Nepal, Pakistan and Bhutan. Some taxonomic authorities continue to place the species in ''Dendrocopos'', while others place it genus '' Leiopicus''. Habitat Its natural habitats are temperate forests and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial f ...s.
