Eurasian Eagle Owls are likely the largest species of owl in the world. Great Grey Owls (Strix nebulosa) are slightly longer in the body, and Blakiston's Fish Owls (Bubo blakistoni) weigh a little more, but only the Eurasian Eagle Owl boasts a six-and-a-half-foot wingspan. Its conspicuous ear tufts are reminiscent of North America's Great Horned Owl (Bubo virginianus), but the Eagle Owl's orange eyes and great size make it distinctive.
As an apex predator, the Eurasian Eagle Owl has no natural predators. Even the Golden Eagle, with whom the Eagle Owl shares both range and food preferences, is seldom in direct conflict with the Owls, thanks to the birds hunting at different times of day (the Golden Eagle in daytime, the Eagle Owl at night). A lifespan of 20 years in the wild isn't uncommon for Eurasian Eagle Owls; birds in captivity have been known to live as much as 60 years.
