Buteo polyosoma

In Bolivia, birds in valleys may be permament residents, while those in puna may be migrants from S. During austral winter, birds from Chilean Andes and Patagonia move N to subtropical lowlands of N & E Argentina, Paraguay and perhaps Uruguay. Formerly thought to be only a migrant to Colombia, but recently reported nesting there.
