The Great Gray Food Groups: Rodents, Rodents, and More Rodents
Photograph by Daniel J. Cox

Great gray owls in the lower 48, like this mother and chicks in Montana, dine on gophers, voles, chipmunks, and just about any other kind of rodent they can get their talons on (above). By contrast, owl populations in Canada and Alaska depend almost exclusively on voles. But wherever they live, great grays consume prodigious quantities of prey. In winter, adults can gulp down as much as a third of their body weight in rodent meals daily.
