Abstract
We present here new data on the distribution and on the density of nesting pairs of the White-throated Hawk (Buteo albigula) in Argentine Patagonia. We report 15 new records with date for this region. We found four nesting territories in an area of approximately 8500 ha on the outskirts of the city of San Carlos de Bariloche, Río Negro. All the nesting territories were within Nothofagus spp. forests. The species was recorded between September and April, confirming its migratory status.
