Gould's Toucanet

Gould's toucanet is about 33 cm (13 in) long. Males weigh 138 to 209 g (4.9 to 7.4 oz) and females 131 to 183 g (4.6 to 6.5 oz). Males and females have the same bill pattern but the female's bill is shorter. The bill's maxilla has a narrow white base, a black middle, an orange-yellow outer third, and ivory "teeth" along the tomium. The mandible's inner half is ivory with a thin black area between it and the outer end's orange-yellow. Both sexes have bare green-yellow to blue skin around the eye and a golden-yellow tuft of feathers behind it; both are paler in the female. Adult males have a black head, nape, chin, throat, and belly. Their upperparts are green with a yellow band on the lower neck. Their tail is green with chestnut tips on the central one to three pairs of feathers. Their flanks are yellow and their undertail coverts are red. Females have chestnut where the male has black, yellower flanks, and a narrower yellow band on the back. Immatures are duller overall, usually without a yellow band on the back, and their bill's pattern is not sharp.

Gould's toucanet is found in central and eastern Brazil south of the Amazon River between the Madeira River and the Atlantic ocean in the state of Ceará, and from there south as far as eastern Bolivia and the Brazilian state of Mato Grosso. It inhabits a variety of tropical forest types, primarily wet lowland and gallery forest but also palm, deciduous, and secondary forest. It favors tall forest (up to 40 m (130 ft) high) but on sandy soils occurs in areas with shorter trees. In elevation it ranges as high as 800 m (2,600 ft) in eastern Amazonia.

Gould's toucanet forages from the forest's undergrowth to its canopy, typically in pairs or groups of up to four. Its diet is known to include fruit and some animal matter but details are lacking.
