Great Horned Owl -- South Dakota Birds

Great Horned Owl

Bubo virginianus

The Great Horned Owl is the most widespread owl in North America, being found from the treeline near the Arctic south through the rest of the continent.  Powerful predators, they will take prey larger and heavier than themselves.  Great Horned Owls are among the earliest nesting birds, starting as early as mid- to late-winter.  

Habitat: Can be found in nearly any habitat in North America, although it requires suitable nesting habitat during its breeding season.

Diet: Wide variety, with more mammals than other types of animals.  Will eat rabbits and hares, rats, mice, ground squirrels, skunks, opossums, snakes, lizards, frogs, large insects, and birds up to the size of geese.  They will take larger prey relative to their size than many birds of prey, even taking on porcupines and similarly sized prey.

Nesting: January through May, one of the earliest nesting birds.
