Crimson-bellied Woodpecker

The crimson-bellied woodpecker is 33 to 34 cm (13 to 13 in) long and weighs 225 to 250 g (7.9 to 8.8 oz). Both sexes have a red forehead, crown, nape, and hindneck, a thin black line above the eye, a thin buff supercilium behind the eye, a wider black band from the nares through the eye to the red of the nape, and a black chin and throat. Males have a buff band between the black eye band and chin; on females the rear of the band extends down the side of the neck to the upper breast. Both sexes' scapulars and upper back are black to brownish black, their lower back and rump are deep red, and their uppertail coverts and tail are black. Their wings' upper surface is black with two white spots on most of the flight feathers. The wings' underside is blackish with pale bars. Their entire underparts from the bottom of the throat are red. Juveniles resemble adults but are duller and browner with a sooty forehead and less red on their underparts.

The crimson-bellied woodpecker is found on the east slope of the Andes from Colombia south through Ecuador and Peru slightly into Bolivia. It mostly inhabits the interior of humid and wet forest, montane forest, and várzea, though it also is found along the forest edge. In elevation it ranges between 500 and 1,500 m (1,600 and 4,900 ft) in Colombia, between about 1,000 and 1,700 m (3,300 and 5,600 ft) in Ecuador, and between 900 and 2,200 m (3,000 and 7,200 ft) in Peru.

The crimson-bellied woodpecker's diet is mostly adults and larvae of large beetles, though other insects are also taken. It usually forages near the ground on the trunks of large trees, by itself or in pairs, hammering and probing to reach the prey.
