Eurasian Eagle-owls are found throughout much of Europe and Asia and in parts of northern Africa. Eurasian Eagle-owls seem to do well in most types of habitat if there are available nesting spots and adequate prey. Eurasian Eagle-owls are mostly nocturnal, or active at night. They spend their days roosting, or resting, in a safe perch. If they spend too much time on the ground, even these top predators may fall prey to opportunistic ground predators like foxes.
