Treated as globally Endangered by BirdLife International, the Wattled Curassow is a large, mainly black, terrestrial cracid, with curled crest feathers and a white vent. The black bill has a reddish cere, knob and wattle. In contrast, the female is black with a rufous vent, and lacks the wattle. The Wattled Curassow’s song consists of a high-pitched, descending whistle, rendered wheeeeeeeee. It inhabits humid lowland, riverine forest, especially seasonally flooded areas, where the species forages in small groups on inundated ground for small fish, insects, aquatic crustaceans, other small animals and fruit. The Wattled Curassow was formerly widespread in upper Amazonia, in western Brazil, southern Colombia, and eastern Ecuador to northern Bolivia, but this overall situation belies the fact that the species’ range has contracted significantly, and it has probably been extirpated locally, including perhaps from Ecuador as a whole, and most of its subpopulations have been recently considered to number fewer than 100 individuals.
