Astur chilensis
The Chilean Hawk (Astur chilensis) is a sleek, medium-sized raptor native to the temperate forests of southern South America, often considered a distinct species from the Bicolored Hawk (Astur bicolor), though historically treated as a subspecies. Adults exhibit striking sexual dimorphism in size, with females being notably larger, typically ranging 42-45 cm in length and weighing 350-500g, while males are smaller, around 37-40 cm and 200-300g; their wingspan averages 69-85 cm. Their plumage ...
This hawk primarily inhabits temperate and humid forests, particularly Nothofagus (southern beech) forests, often favoring areas with clearings or forest edges. It is found from sea level up to elevations of approximately 1,800 meters in the Andean foothills.
The Chilean Hawk's diet consists primarily of small to medium-sized birds, which it ambushes with incredible speed and agility within dense forest. It also preys on small mammals, reptiles, and large insects when opportunities arise, capturing them with its powerful talons.
Chilean Hawks are largely diurnal, exhibiting crepuscular activity during prime hunting times, and typically roost solitarily or in pairs within dense forest canopy. They are highly agile and secretive hunters, employing a 'perch-and-pounce' or 'dash-and-grab' foraging strategy, often launching s...
The Chilean Hawk is endemic to the temperate forests of southern South America, primarily ranging through southern Chile and adjacent areas of southwestern Argentina. Its breeding range extends from approximately central Chile (Biobío Region) southward through Patagonia to Tierra del Fuego. In Ar...
