Magellanic Horned Owl
Bubo virginianus magellanicusAlso known as Lesser Horned Owl, Tucúquere, Magellanic Owl
Magellanic horned owls hunt from elevated perches along Andean cliffs and Patagonian woodlands, dropping silently onto rodents, birds, and small reptiles. Their musical calls feature a distinct double note cadence that echoes across southern canyonlands during dusk displays. These adaptable raptors nest in tree hollows, cliff ledges, or abandoned stick nests built by other large birds.
