Great Horned Owls Thaw Cached Prey

1-13-14 great horned owl l MH_20091001_225056_4Great Horned Owls are one of the earliest species of birds to nest in the Northeast –some are already sitting on eggs. Female Great Horned Owls do the lion’s share of incubating the eggs, while the male hunts for and brings her food. While they do eat small rodents, which they swallow whole, the diet of Great Horned Owls also consists of rabbits, hares, opossums, squirrels and skunks, which must be torn into small pieces before being swallowed. Great Horned Owls often kill more than they can eat at one time, and cache the extra food for later consumption, when food is scarce. Needless to say, during winter months the cached prey freezes, and if the prey is large, its consumption is challenging for a bird with a bill that’s designed for shredding and tearing. To solve this dilemma, Great Horned Owls sit on their frozen prey until it thaws, and then proceed to tear it into bite-size pieces.
