Crestless Curassow
Appearance: The Crestless Curassow is a striking bird with glossy black plumage, a white belly, red eyes, and a brightly colored yellow bill. It lacks the crest seen in some other curassow species.
Habitat: These birds are found in the lowland primary and secondary forests. They prefer dense, humid habitats with a variety of fruits, seeds, and insects available for food.
Behavior: Crestless Curassows are shy and elusive birds, often foraging quietly on the forest floor for food. They are known to be territorial and may use vocalizations to establish boundaries or attract mates. Their flight is short and labored, and they spend most of their time on the ground.
Breeding: During the breeding season, which occurs in the wetter months, Crestless Curassows engage in courtship displays that include vocalizations, strutting, and other visual cues. Females lay a small clutch of eggs in a shallow nest on the forest floor, and both parents share incubation duties.
Conservation Status: The Crestless Curassow is listed as Critically Endangered by the IUCN. The Crestless Curassow, one of the most critically endangered bird species in the world, is native to the tropical forests of Colombia.
Distribution
Amazon Region: Parts of the Amazon region in the departments of Putumayo and Caquetá that support populations of the Crestless Curassow. The species thrives in the humid lowland rainforests characteristic of the Amazon basin.
Central Region: The central region of Colombia, including areas like Meta and Guaviare departments, may also have pockets of habitat fit for the Crestless Curassow. However, deforestation and habitat degradation in this region pose significant challenges to the species.
Eastern Plains (Llanos): Some reports suggest that the Crestless Curassow may also be present in the Eastern Plains region known as the Llanos. These grasslands and savannas are interspersed with gallery forests that could provide habitat for the bird.

Vocalization
The male Crestless Curassow is known for its vocalizations, particularly during the breeding season as a part of courtship displays and territorial communication. The vocal repertoire of the male Crestless Curassow includes a variety of sounds such as low-frequency booming calls, deep guttural grunts, and occasional whistles.
These vocalizations are used to attract mates, establish dominance, warn off rivals, and maintain contact with their social group. The booming calls are resonant and can carry over long distances through the dense forest canopy. These calls consist of a series of deep, booming notes that may vary in pitch and intensity. The grunts are used more for short-distance communication and are often associated with aggressive interactions or territorial disputes.
