Crestless Curassow Mitu tomentosum

Also known as the Lesser Razor-billed Curassow, and occasionally placed in the genus Crax, this species ranges across much of the Guianan Shield, reaching its southernmost limit near the Brazilian city of Manaus, but is nowhere more than locally common. This curassow is shy and largely terrestrial, feeding on a variety of different fruits, although it retreats to the canopy if flushed. Vocal activity continues year-round, but increases dramatically in the breeding period, which appears to coincide with the early wet season, although few definitive nesting data are currently available. The Crestless Curassow is principally black, glossed variously dark blue to purplish, marked by a chestnut abdominal region and possessing a red bill that is distinctly less modified than that of its closest relatives, the Razor-billed Curassow (Mitu tuberosum) and the Alagoas Curassow (Mitu mitu). It prefers dense lowland forest usually in close proximity to watercourses, including gallery forests in savanna, on river islands, and in seasonally flooded areas, always below approximately 600 m.
