Enjoy this fantastic close-up photo of a female Powerful Woodpecker taken in Colombia by Juan Carlos L. This bird lives in the Andes mountains, from Central Colombia to Peru. Notice the "v" shape the white lines make on the back, a pattern shared by several members of the genus. Male birds have a red forehead and crest. The photo is posted here with permission.

Mégapic de Gray, the Powerful Woodpecker
The illustration above is Plate V. from Alfred Mahlerbe's Monographie des Picidées. It depicts a family group consisting of a male Powerful Woodpecker in left, foreground, a female in the background and a male juvenile bird.
Here is an excerpt listing various names for the Powerful Woodpecker from the 1868 publication entitled List of the Specimens of Birds in the Collection of the British Museum by George Robert Gray, creator of the Campephilus genus, et al. It is available here at Google books.

Nesting Biology of the Powerful Woodpecker
The Powerful Woodpecker was named long ago, in 1845 by Charles Lucien Bonaparte, a French naturalist and ornithologist who was the nephew of famed Emperor Napoleon.
These 165 years later, very little is known about the breeding biology of this bird, an uncommon resident of montane regions from Venezuela to Peru (according to the article cited herein). The remarkable photos you see here are two of several within an article entitled First description of the eggs and nestlings of Powerful Woodpecker (Campephilus pollens) by Harold F. Greeney, Jose Simbaña & Lucia A. Salazar-V., and published February 26, 2010 in Boletín SAO in which the authors state:
on the eggs and nestlings of this poorly known species.

Many thanks to WLA on Flickr for sharing this photo of a juvenile male Powerful Woodpecker, who also offers this interesting info:
This photo displays the classic arrangement of toes in Campephilus woodpeckers. It is not the zygodactly arrangement typical of so many other woodpeckers, of two pairs of toes arranged opposite each other, pointing top and bottom. Rather, the third toe of the bird is elongated and extended horizontally to brace the large bird against a tree trunk, as a person on a very narrow cliff face might extend each arm to brace him or herself against the cliff.
Consider this when you see in illustrations of Ivory-billed Woodpeckers and other Campephilus species because the illustrators too often go with the incorrect zygodactyl toe arrangement that's typical of many other woodpeckers, but not those in the Campephilus genus.
