Pseudasturidae

The Pseudasturidae is a family of birds of prey that belongs to the order Accipitriformes, commonly known as hawks, eagles, and kites. This family is relatively small and consists of only two genera: *Pseudastur* and *Geranoaetus*, with a total of four species. The group is primarily found in the Neotropical region, encompassing parts of Central and South America.

Pseudasturidae members are medium-sized raptors, typically characterized by their broad wings, short tails, and robust bodies. Their plumage is often dark with contrasting lighter markings, such as white or pale gray, which may vary depending on the species. These birds are known for their strong hunting abilities, feeding primarily on small mammals, birds, and occasionally reptiles or amphibians. Their diet and behavior suggest they are opportunistic hunters, adapting to various habitats including forests, grasslands, and open woodlands.

The genus *Pseudastur* includes two species: the Black-chested Buzzard-Eagle (*Pseudastur polionotus*) and the Black-and-chestnut Eagle (*Pseudastur polionotus* was previously considered a single species, but recent taxonomic revisions have split it into two distinct species: *P. polionotus* and *P. ruficeps*). The genus *Geranoaetus* contains two species: the Crane Hawk (*Geranoaetus polyosoma*) and the Black-chested Buzzard-Eagle (*Geranoaetus melanoleucus*), though the latter is sometimes classified under *Pseudastur* based on genetic studies.

These birds are generally solitary or found in pairs, with little social interaction beyond mating. Nesting occurs in trees, and both parents participate in incubation and raising the young. Pseudasturidae species are not currently considered globally threatened, though some populations face local declines due to habitat loss and persecution. Conservation efforts focus on protecting their natural habitats and reducing human-wildlife conflict.
