Piculus is a genus of birds in the woodpecker family Picidae that are found in Central and South America.
The genus was introduced by the German naturalist Johann Baptist von Spix in 1824.[2] The type species was subsequently designated as the golden-green woodpecker (Piculus chrysochloros) by the American ornithologist Harry C. Oberholser in 1923.[3] The generic name is a diminutive of the Latin word Picus meaning "woodpecker".[4]
The genus forms part of the woodpecker subfamily Picinae and has a sister relationship to the genus Dryocopus whose species are found in Eurasia and the Americas. The genus Piculus is a member of the tribe Picini and belongs to a clade that contains five genera: Colaptes, Piculus, Mulleripicus, Dryocopus and Celeus.[5]
