Colaptes

Colaptes woodpeckers typically have a brown or green back and wings with black barring, and a beige to yellowish underside, with black spotting or barring. There are usually colorful markings on the head. Many of these birds – particularly the northern species – are more terrestrial than usual among woodpeckers.

Historically, there has been considerable uncertainty in assigning woodpecker species to genera and it is only by comparing DNA sequences that it has become possible to confidently place many of the species.

Taxonomy

The genus Colaptes was introduced by the Irish zoologist Nicholas Aylward Vigors in 1825 with the northern flicker (Colaptes auratus) as the type species. The genus name is from Ancient Greek κολάπτης (koláptēs), meaning 'chiseller, pecker'.

The genus forms part of the woodpecker subfamily Picinae and has a sister relationship to the genus Piculus. The genus Colaptes is a member of the tribe Picini and belongs to a clade that contains five genera: Colaptes, Piculus, Mulleripicus, Dryocopus and Celeus. Some of the relationships between the species within Colaptes are uncertain, with various genetic studies reporting slightly different phylogenies, but it is evident that those species with "flicker" in their common name do not form a monophyletic group.

The genus Colaptes contains 14 species. Of these, one, the Bermuda flicker, is now extinct:
