Conservation status according to BirdLife International: Least Concern


Description


A medium-to-large raptor with an elegant outline, easily recognized by the contrast between its dark brown body, rich rufous wing coverts, and paler legs and tail base. A prominent white tail band is visible both perched and in flight. Its robust head, hooked bluish-gray bill and long yellowish tarsi lend it a powerful and agile appearance, well suited for maneuvering through shrubs and open spaces.

Geographical distribution: Ranges widely across the Americas, from the southwestern United States and Mexico through Central America and extensive areas of South America, including Brazil, Bolivia, Paraguay, Uruguay, Chile, and Argentina. It is most common in arid and semiarid regions with low vegetation, where small prey and elevated perches are readily available.

Habitat: Occupies open or semi-open environments such as scrublands, savannas, dry forests, arid zones, grasslands, and rural landscapes with scattered trees. It tolerates modified habitats when they provide open spaces for hunting and natural or artificial structures for perching.

Diet: Predominantly consumes small mammals, small birds, reptiles and occasionally large insects. A versatile hunter, it combines low flights, short pursuits and ambushes from elevated perches. One of its most distinctive traits is the ability to engage in cooperative hunting, where coordinated group strategies greatly increase capture success.

Behavior: Notably social for a raptor, forming family groups that may include several individuals assisting in territory defense, hunting and raising the young. Its flight is broad and controlled, alternating glides with strong wingbeats. Frequent use of fence posts, branches and other elevated points reflects its constant vigilance behavior.

Breeding: Builds nests in medium to tall trees, on columnar cacti or occasionally on human-made structures. Nests consist of sturdy branches forming a platform reused over multiple seasons. Typical clutches contain two to four eggs, mostly incubated by the female. Juveniles remain with the group for an extended period, learning cooperative hunting before dispersing.

Conservation status: Listed as Least Concern, with stable populations throughout most of its range. Its cooperative behavior and adaptability to open habitats favor its persistence, though localized threats include habitat degradation and persecution.
