brunhokko Nothocrax urumutum

This small curassow is entirely warm brown with a bright orange bill, yellow skin above the eye, and gray skin below the eye. True to its name, it is strictly nocturnal and thus extremely difficult to see. It is much more often detected by voice: listen for a low, booming song typically with three notes. With a great deal of effort and luck, a singing individual might be spotted perched in the canopy. Occurs in lowland forest in western Amazonia, where it typically stays in the upper levels, rarely dropping to the ground.
