The Red-headed Woodpecker, Melanerpes erythrocephalus, is a small or medium-sized woodpecker from temperate North America. Their breeding habitat is open country across southern Canada and the eastern-central United States.

[edit] Taxonomy

The Red-headed Woodpecker's distinct colors are true to the bird's name.

The Red-headed Woodpecker was one of the many species originally described by Linnaeus in his 18th-century work Systema Naturae.[1] The specific epithet is derived from the Ancient Greek words erythros 'red' and kephalos 'head'.[2]

There are three subspecies recognized:

  • Melanerpes erythrocephalus brodkorbi
  • Melanerpes erythrocephalus caurinus
  • Melanerpes erythrocephalus erythrocephalus

[edit] Description

Adults are strikingly tri-colored, with a black back and tail and a red head and neck. Their underparts are mainly white. The wings are black with white secondary remiges. Adult males and females are identical in plumage.[3] Juveniles are similarly shaded, but are mottled with brown.[3] Non-birders often mistakenly identify the rather misnamed Red-bellied Woodpecker as this species. That species has some red on the head, but across most of its range the fully and dark red head and the bold patches of color are unmistakable.

They give a tchur-tchur call or drum on territory.

[edit] Behaviour

These birds fly to catch insects in the air or on the ground, forage on trees or gather and store nuts. They are omnivorous, eating insects, seeds, fruits, berries, nuts, and occasionally even the eggs of other birds.[3] About two thirds of their diet is made up of plants.[3] They nest in a cavity in a dead tree, utility pole, or a dead part of a tree that is between 8 and 80 feet (2.5 to 25 m) above the ground.[3] They lay four to seven eggs in early May which are incubated for two weeks.[3] Two broods can be raised in a single nesting season.[3] Northern birds migrate to the southern parts of the range, with most having arrived on the breeding range by late April, and having left for winter quarters by late October;[4] southern birds are often permanent residents.

[edit] Conservation

Once abundant, populations have seriously declined since 1966 due to increased nest site competition from European Starlings and removal of dead trees (used as nesting sites) from woodlands. Many Northeastern states no longer have nesting red-headed woodpeckers. In Ohio, for example, an irregular population is present in most years, but it is not self-sustaining.[5]

The red-headed woodpecker is listed as a vulnerable species in Canada and as a threatened species in some states in the US. The species has declined in numbers due to habitat loss caused by harvesting of snags, agricultural development, channeling of rivers, a decline in farming resulting to regeneration of eastern forests, monoculture crops, the loss of small orchards, and treatment of telephone poles with creosote.[6]

[edit] Popular culture

In 1996, the United States Postal Service issued a 2-cent postage stamp depicting a perched red-headed woodpecker.[7] The stamp was discontinued at some time thereafter, but re-issued in 1999 and remained available for purchase until 2006.[8]

The classic-era cartoon character Woody Woodpecker is a generally identified as a Red-headed Woodpecker as it has the unique all-red head. The body coloration is somewhat modified for design purposes, and the tuft of large US woodpeckers (like the Pileated or the Ivory-billed Woodpecker) are added.
