Species of bird

The white throated hawk (Buteo albigula) is a bird of prey in subfamily Buteoninae, the "soaring" hawks, of family Accipitridae. It is found in Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela.

The white throated hawk has at various times been considered a dubious taxon, a subspecies of short tailed hawk (B. brachyurus), or a sister species with the short tailed. None of these treatments are currently (2022) accepted.

The white throated hawk is found in the Andes from northwestern Venezuela south through Colombia and Ecuador into Peru and Bolivia and in central Chile and western Argentina. It inhabits humid montane forest, elfin forest, cloudforest and adjacent open landscapes such as puna grassland. In the northern part of its range it is found at elevations between , in Patagonia between , and in Chile from near sea level to .

The white throated hawk is certainly migratory in the southern part of its range, moving north in the non breeding season. Its behavior in its northern range is not well known. Some authors believe that all of the northern occurrences are by migrants from the south; others believe that at least in some northern areas they are year round residents with some migrants from the south also present in the austral winter. The South American Classification Committee of the American Ornithological Society lists it as a non breeding visitor to Bolivia and Ecuador, hinting that it only passes through those countries in migration.

The white throated hawk's hunting strategy has not been documented. Its diet has not been extensively studied but is known to include insects, rodents, and birds, the last as large as Magellanic woodpecker (Campephilus magellanicus).

The white throated hawk is known to breed only in Chile and Argentina, though there is limited evidence that it also breeds in parts of its northern range. Its breeding season spans from September at least to April. Pairs make undulating display flights. The nest is made of live and dead sticks and often is covered with lichen, and is placed above the ground. The clutch size is one or two eggs that are incubated mostly by the female. The incubation period is about one month and fledging occurs about 40 days after hatch. Males provision the female and young.

The white throated hawk is thought to be mostly silent. It does make a "squealing 'kee ah' during breeding season".

The IUCN has assessed the white throated hawk as being of Least Concern. It has a fairly large range. The trend of its estimated population of 670 to 6700 mature individuals is not known. No immediate threats have been identified. In its known breeding range it is considered uncommon to fairly common but rare and local in much of its northern range. "Preferred altitudinal range relatively less affected by human activities, especially transformation; also shows tolerance of disturbed habitat."
