The Caatinga Woodpecker or Kaempfer's Woodpecker (Celeus obrieni) is a species of woodpecker from Brazil. The type specimen, a female, was collected in the Brazilian state of Piauí in 1926. No other individuals were collected or seen and the bird was feared extinct, until a male was captured during mist netting in 2006 in the state of Tocantins. The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. ...

Normally, it has been considered a subspecies of the Rufous-headed Woodpecker (Celeus spectabilis), but an evaluation by the South American Classification Committee (SACC) in 2006 resulted in it being recognized as a distinct species. This was based on the the differences in habitat, size and plumage, combined with the large distance (more than 3000 kilometers [1850 mi]) between the ranges of the two species. In zoology, as in other branches of biology, subspecies is the rank immediately subordinate to a species. ... In biology, a species is one of the basic units of biodiversity. ...

It has a total length of about 24 centimeters (9½ in). The head and remiges are mainly rufous-chestnut, the underparts and back are buff, the wing-coverts are barred in black and buff and the chest and tail are uniform black. The male has a red malar and mottling on its crest. For comparison, the Rufous-headed Woodpecker is larger and has extensive black barring on the back and underparts. Remiges are a birds flight feathers which are attached to the rear portion of the wing bones. ... Buff is a pale yellow-brown colour that got its name from the colour of buffalo leather. ...

Little is known about its habitat preference, but it appears to be Cerrado and babassu palm forest; very unlike the humid forest where the Rufous-headed Woodpecker is found. There is no evidence to suggest that it occurs in Caatinga. This has lead to Kaempfer's Woodpecker being suggested as a common name instead of Caatinga Woodpecker. The new name honours Emil Kaempfer who collected the type. The cerrado (Portuguese: thick, dense) is a vast area of savanna-like grasslands in Brazil. ... Binomial name Orbignya phalerata Mart. ...

Being known from only two individuals in a habitat that is disappearing fast, it must be highly endangered. However, due to the taxonomic confusion with the Rufous-headed Woodpecker, it has only recently been evaluated by BirdLife International where it was given the status of Critically Endangered for the 2007 Red List.
