Crestless Curassow

Mitu tomentosum

Also known as Lesser Razor-billed Curassow

Crestless curassows patrol the shaded floors of northern Amazonian and Orinoco basin forests, stepping quietly in pairs or small family groups to glean fallen fruits. Unlike their shaggy-crested relatives, they display a smooth, velvety black crown alongside a bright red curved bill and rich chestnut undertails. Territorial males project deep, low-frequency booming calls that reverberate through the lower canopy around dawn and dusk.
