About Selenidera piperivora (Linnaeus, 1758)
The Guianan toucanet (Selenidera piperivora) is 33 to 35 cm (13 to 14 in) long. Males weigh between 129 and 159 g (4.6 to 5.6 oz), while females weigh between 132 and 165 g (4.7 to 5.8 oz). Males and females share the same bill pattern, though the female's bill is shorter. A yellowish line runs along the base of the bill. Both the upper (maxilla) and lower (mandible) mandibles are mostly black with red bases; the red color extends further onto the mandible. Both sexes have bare blue skin surrounding the eye, with a tuft of yellow feathers positioned behind this blue skin. Males have black plumage on the crown, nape, throat, breast, and belly. They have a gold "collar" on the upper back, and the rest of their upperparts are green. Their tail is green, with chestnut-colored feather tips. Their undertail coverts are red. Adult females have a black cap, with chestnut-colored nape and upper back, and only a faint hint of a yellow collar. Their underparts are gray to green-gray, with a green-yellow belly. Immature Guianan toucanets are similar to adults but are overall duller, with less distinct plumage and bill patterns. The Guianan toucanet ranges from extreme southeastern Venezuela east through the Guianas into northern Brazil, and extends south to the Amazon River between the Rio Negro and the Amazon's mouth in the state of Amapá. It lives in moist forest, including gallery forest in savannas, and prefers primary forest over selectively logged areas. In most of its range, it occurs at elevations up to 600 m (2,000 ft), but it can be found as high as 900 m (3,000 ft) in Venezuela and Suriname.
