The conservation status of a Species is an indicator of the likelihood of that species remaining extant either in the present day or the near future Least Concern ( LC) is an IUCN category assigned to extant species or lower taxa which have been evaluated but do not qualify for any other category Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. Six families of largely arboreal Birds make up the order Piciformes, the best-known of them being the Picidae which includes the Woodpeckers Picoides is a Genus of Woodpeckers ( family Picidae) found primarily in North America. villosus

The Hairy Woodpecker (Picoides villosus) is a medium-sized woodpecker. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for In Scientific nomenclature, synonyms are different Scientific names used for a single Taxon. The woodpeckers, piculets and wrynecks are a family, Picidae, of Near-passerine Birds.

Habitat

Their breeding habitat is forested areas with large trees across most of

North America to Central America. They nest in a tree cavity, excavated by the nesting pair.

Description

Adults are mainly black on the upper parts and wings, with a white back, throat and belly and white spotting on the wings. There is a white bar above and below the eye. They have a black tail with white outer feathers. Adult males have a red patch on the back of the head.

It is virtually identical in plumage pattern and coloration to the much smaller Downy Woodpecker, which also has a shorter bill relative to the size of its head. The Downy Woodpecker, Picoides pubescens, is the smallest Woodpecker in North America. These two species are not at all closely related, however, and are to be separated in different genera (Weibel & Moore, 2005; Moore et al. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic , 2006). Their outward similarity is a spectacular example of convergent evolution. Convergent evolution describes the acquisition of the same biological trait in unrelated lineages As to why this convergence has evolved, only tentative hypotheses have been advanced; it is interesting to note in any case that due to the considerable size difference, ecological competition between the two species is rather slight. Ecology (from Greek grc οἶκος oikos, "house(hold" and grc -λογία -logia) is the scientific study of

These birds are mostly permanent residents. Birds in the extreme north may migrate further south; birds in mountainous areas may move to lower elevations. Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability

These birds forage on trees, often turning over bark or excavating to uncover insects. Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described They mainly eat insects, also fruits, berries and nuts, sometimes tree sap. The term fruit has different meanings dependent on context and the term is not synonymous in Food preparation and Biology.
