The Eurasian Eagle-Owl (Bubo bubo) also called the Uhu, or sometimes abbreviated to just eagle-owl in Europe, is a species of eagle-owl native to much of Eurasia. They are a very powerful species of owl and can take down very large prey throughout their range. It's a close relative of the great horned owl of the Americas.
The major part of their diet consists of mammals (e.g., voles, rats, mice, foxes, hares), but birds of all kinds are also taken, including crows, ducks, grouse, seabirds, and even other birds of prey (including other owls).
