Golden-collared toucanet

The golden-collared toucanet (Selenidera reinwardtii) is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru.

The golden-collared toucanet is 33 to 35 cm (13 to 14 in) long. The nominate subspecies weighs 129 to 178 g (4.6 to 6.3 oz) and S. r. langsdorffii 134 to 200 g (4.7 to 7.1 oz). The two subspecies have essentially the same plumage. Adult males have a black head, nape, and shoulders. A narrow yellow band separates the black shoulders from the green back. Their tail is green with chestnut tips on the central two or three pairs of feathers. Their eye is surrounded by bare blue skin (greener in S. r. langsdorffii) and a golden-yellow tuft of feathers protrudes behind it. They have mostly black underparts with gold-yellow flanks (more orange in S. r. langsdorffii) and red undertail coverts. Adult females replace the male's black with chestnut; their facial tuft and flanks are duller, and the yellow band on the back is narrower. Immatures are duller overall with rusty undertail coverts.

The golden-collared toucanet subspecies' bills differ; within each the sexes have the same pattern, but the female's is shorter. The nominate's bill has a vertical black line at the base and a black culmen. Most of the bill is red, with approximately the outer third black. The maxilla has black to ivory "teeth" along the tomium. S. r. langsdorffii's bill has a mostly black maxilla with a green base and a roughly half-and-half green and black mandible. However, the bill is sometimes almost entirely black. The tomial "teeth" are creamy to whitish.
