Description: It is a medium-sized bird with a robust build and upright posture, showing clear sexual dimorphism. The male displays glossy black plumage with bluish or purplish iridescence, while the female is much duller, with brownish to grayish tones and fine streaking. The bill is short, strong, and conical, suited to a varied diet, and the dark eyes give it an alert expression.

Geographic distribution: It is widely distributed throughout South America, with natural and human-facilitated expansion into Central America and parts of the Caribbean. It is one of the most widespread species within its genus.

Habitat: It primarily inhabits open and semi-open environments, such as grasslands, farmland, rural areas, city outskirts, and urban parks. Its high tolerance for human-altered landscapes has greatly contributed to its geographic expansion.

Feeding: This species is omnivorous, feeding mainly on seeds, grains, and small invertebrates such as insects and larvae. It often forages on the ground, alone or in groups, frequently taking advantage of resources associated with livestock and agriculture.

Behavior: It is a gregarious and opportunistic species, commonly seen in flocks, especially outside the breeding season. It shows confident and adaptable behavior, often frequenting areas with intense human activity. During reproduction, females exhibit particularly stealthy behavior.

Nesting: It has a distinctive reproductive strategy known as brood parasitism, as it does not build its own nest. Females lay their eggs in the nests of other bird species, which then incubate the eggs and raise the chicks. The young often grow rapidly and may outcompete or displace the host’s offspring.

Conservation status: It is classified as Least Concern, due to its wide distribution, large population size, and strong adaptability. No significant global threats are currently identified.
