Amazonian Umbrellabird
Cephalopterus ornatus
Much larger than the female, the male Amazonian umbrellabird is likely the largest passerine in South America as well as the largest suboscine passerine in the world. The male Amazonian umbrellabird grows to a weight of 480–571 grams (1.06–1.26 lb) and a length of 48–55 centimetres (18.9–21.7 in). The female typically stands 41–44 centimetres (16.1–17.3 in) tall and weighs up to 380 grams (0.84 lb).

Long-wattled Umbrellabird
Cephalopterus penduliger
The male is 40–42 cm in height, with the female being slightly smaller at 35–37 cm. Both sexes are short-tailed and carry an erectile head crest; those of the males are slightly longer at 20–30 cm. The male is distinguished by a large throat wattle of feathers, while females and juveniles have no or a much smaller wattle. The length of the wattle can be controlled, and it can be retracted in flight. The male generally has black colored shafts in its feathers. The long-wattled umbrellabird's specific name penduliger derives from Latin pendulus, hanging, and refers to the wattle.
