Records from Chascomús

Conservation status according to BirdLife International: Least Concern

Description: It is a medium-sized diurnal raptor with a compact and sturdy build, easily recognized by its relatively large head and strong, hooked bill with a yellow base. Plumage coloration is variable but typically shows brown to grayish tones, with finely barred underparts. The wings are short and broad, and the tail is relatively short with distinct dark bands. The legs are yellow and powerful, adapted for capturing a wide range of prey.

Geographic distribution: It has a very wide distribution throughout the Americas, ranging from southern Mexico and Central America to much of South America, including most of Argentina. It is absent only from extremely arid regions or high mountain areas.

Habitat: It occupies a broad range of open and semi-open habitats, such as savannas, forest edges, woodlands, farmland, and urban or suburban areas. It shows remarkable adaptability to human-modified environments, contributing to its widespread presence.

Feeding: It has an opportunistic carnivorous diet, feeding on small mammals, birds, reptiles, amphibians, and large insects. Carrion may also be consumed occasionally. Prey is often captured from elevated perches, using short and accurate swoops.

Behavior: It is a territorial and conspicuous bird, frequently seen perched on poles, trees, or wires. Its sharp, repetitive calls are highly characteristic. Individuals are usually observed alone or in pairs, defending well-defined territories year-round.

Nesting: Nesting occurs in medium to tall trees, where a bulky stick nest lined with green leaves is built. The typical clutch consists of 1 to 3 eggs, mainly incubated by the female, while the male assists with food delivery and nest defense.

Conservation status: It is classified as Least Concern, with stable and widespread populations. Its high ecological flexibility allows it to withstand environmental changes that negatively affect other raptor species.
