Distribution in the Americas

Razor-billed Curassow is widespread in Amazonia, from southeastern Colombia south to Cochabamba and Santa Cruz, Bolivia, and east across Brazil, south of the Amazon, to eastern Pará, Brazil (Hellmayr and Conover 1942, Vaurie 1967, Hilty and Brown 1986, Hennessey et al. 2003, Schulenberg et al. 2007). Razor-billed Curassow does not occur in Ecuador (Ridgely and Greenfield 2001). Although Razor-billed Curassow primarily occurs south of the Amazon, it is present north of the Amazon from extreme eastern Peru and in southeastern Colombia east to the west bank of the lower Rio Negro (Niceforo Maria and Olivares 1965, Scheuerman 1977, Borges et al. 2001).

The elevational range of Razor-billed Curassow is from the lowlands up to 1350 m (Weske 1972, Schulenberg et al. 2007), although perhaps it occurs above 900-1000 m only locally (e.g. Hennessey et al. 2003, Walker et al. 2006).

Distribution outside the Americas

No species of curassow occur outside of South America.

Habitat

Razor-billed Curassow occurs in lowland evergreen forest. It perhaps is most widespread in terra firme forest, but also occurs in gallery forest, transitional (seasonally flooded) forests, around lake margins, and at forest stream margins (Terborgh et al. 1984, del Hoyo and Motis 2004).

Historical changes

Razor-billed Curassow is vulnerable to hunting pressure, and is extirpated from some areas within its range (e.g. Novaes and Lima 1998, Schulenberg et al. 2007).

Fossil history

None reported.
