R
starts withThe razor-billed curassow is 83 to 89 cm (2.7 to 2.9 ft) long and males weigh about 3,860 g (8.5 lb). Their plumage is mostly black with a strong purplish blue gloss. The lower belly and undertail coverts are chestnut and the tips of the tail feathers white. It has a tall ragged crest. Its large bright red bill is laterally compressed, which gives the species its common name.
The razor-billed curassow is found in much of Amazonia, mostly south of the Amazon River in eastern Peru, northern Boliva, and northern Brazil all the way to the Atlantic coast. It is found north of the Amazon in southeastern Colombia, extreme northeastern Peru, and Brazil as far east as the Rio Negro. It inhabits lowland evergreen forest, primarily terra firme but also gallery and várzea forests and along the margins of lakes and streams. In elevation it ranges from sea level to 1,350 m (4,400 ft) though it may only locally exceed 1,000 m (3,300 ft).
The razor-billed curassow typically forages alone or in pairs on the forest floor. Its diet is mostly fallen fruits and also includes leaves, insects, fungi, and small vertebrates.
The razor-billed curassow is occasionally polygynous and might be regularly so. In northern Peru at least, its nesting season spans from November to February. One nest was described as "a perfect round cup" of branches, lianas, and leaves. The clutch size is two or three eggs.
The IUCN has assessed the razor-billed curassow as being of Least Concern. It has a very large range. However, its population has not been quantified and is believed to be declining, primarily because of heavy hunting pressure.
