Naster

Naster is a genus of small to medium-sized birds of prey in the family Accipitridae. The genus is native to the Americas, with species ranging from the southern United States to Argentina. Naster birds are known for their distinctive appearance, with a long, wedge-shaped tail and a broad, rounded head. They are typically brown or gray in color, with a white or buff belly and a dark band across the chest.

The genus includes two recognized species: the Black-chested Buzzard-Eagle (Naster maculatus) and the White-tailed Buzzard-Eagle (Naster coryi). Both species are adapted to hunting in open habitats, such as grasslands and savannas. They are known for their powerful flight and their ability to soar for long distances. Naster birds are also known for their distinctive calls, which are often described as a loud, booming sound.

Naster birds play an important role in their ecosystems, as they help to control populations of small mammals and other prey species. They are also an important food source for other birds of prey and scavengers. However, their populations have declined in some areas due to habitat loss and other factors. Conservation efforts are underway to protect these birds and their habitats.
