Colinus cristatus is distributed across northern South America. It prefers open scrubland, savannas, forest edges, and agricultural fields, particularly those with a mix of low vegetation and scattered cover. This bird may be observed near human-modified environments, including pastures, rural farmlands, and scrubby roadsides, particularly in regions where dense forest has been cleared. It is not confined to protected areas and may persist near rural dwellings and degraded land.

Adult individuals measure approximately 9 to 10 inches in length. Males display a pronounced double plume or crest formed by elongated crown feathers, which curve slightly forward. Their plumage features warm reddish tones, black-and-white spotting on the flanks and throat, and variable patterns of pale underparts and darker dorsal surfaces. The species emits a distinctive whistled call that can vary regionally. It lives in small coveys of up to a dozen birds, often foraging on the ground for seeds, insects, and berries. When disturbed, it tends to run through dense cover rather than immediately flying. Nests are usually dome-shaped and built on the ground, hidden by grass or low vegetation. Pairs are monogamous, and both sexes may participate in brood care. Predation pressure from raptors, snakes, and small mammals has shaped its cautious and cryptic behavior.

Colinus cristatus is classified as a species of Least Concern by the IUCN. Despite ongoing habitat loss in some regions, it is considered relatively adaptable. Small-scale game farms or private breeders in Venezuela and Colombia raise it for regional hunting or ornamental display.
