This medium-sized raptor is known for its remarkable adaptability and opportunistic habits. Its plumage is mostly brownish, with paler underparts and subtle barring on the wings and tail. The bill is short and slightly hooked, while the yellowish legs are strong and well adapted for extensive walking. Its flight is characterized by broad wings and a long tail that provides fine control during turns. Juveniles tend to be darker and more heavily patterned than adults.
Geographical distribution: It occurs across a broad portion of South America, from central and southern Brazil through Paraguay, Uruguay, Bolivia, Chile and much of Argentina, reaching the southern tip of the continent. It is particularly abundant in temperate and open regions. In some areas it shows seasonal movements linked to food availability and climatic shifts.
Habitat: It occupies many types of environments, including grasslands, shrublands, rural landscapes, urban areas, roadsides, garbage sites and livestock fields. It adapts easily to human-modified settings where food is abundant. Open or semi-open habitats are preferred, as they facilitate low flights and ground foraging.
Diet: The species has a highly flexible and opportunistic diet. It feeds on small vertebrates, reptiles, insects, carrion, food scraps and prey associated with human activities. In rural or suburban areas it frequently uses slaughterhouses, dump sites and work areas, obtaining resources with minimal effort. It also chases flying insects or captures prey on the ground thanks to its notable agility.
Behavior: It is a social bird, often gathering in large groups, especially at communal roosts or sites with plentiful food. It shows bold behaviors, approaching human activity or competing assertively with other species. Its call is a distinctive, somewhat plaintive sound. The species spends considerable time walking and foraging on the ground, displaying confident movements. During flight it uses broad glides and energy-efficient movements.
Breeding: Nests are usually placed on trees, man-made structures or natural embankments. The nest is a simple platform built with sticks and assorted materials. Clutches typically contain two to three eggs, incubated mainly by the female. The chicks remain in the nest for several weeks and are fed by both adults.
Conservation status: Classified as Least Concern (LC) at the global level due to its wide distribution, tolerance of human-altered environments and stable or increasing population in many regions. Its ecological success stems from its exceptional flexibility and ability to exploit diverse food sources.
