Eurasian Eagle Owl
One of the largest types of owls, the Eurasian Eagle Owl is a resident of Eurasia, with a diverse potential habitat but sparsely distributed. They have been found in northern coniferous forests, deserts, rocky mountainous areas, taiga, steppe, and grasslands. The owl has a body length of 23–30 in, a wingspan of 55–79 in, and females weigh 3.9-10 lbs, while males weigh 3.3-7 lb. Their great size, orange eyes, and ear tufts are distinct, and its tendency to soar on updrafts is unusual for owls. Its main sources of food are small mammals in the 0.44-4.4 lb weight range, such as mice, rats, hares, and voles. However, they might hunt birds, amphibians, reptiles, fish, and insects, and can kill prey up to the size of foxes, marmots, and young deer if taken by surprise. Females lay 2-4 eggs, and the owls are sexually mature at 2 to 3 years.
The Eurasian Eagle Owl is largely nocturnal, and prefers to nest on cliff ledges and rock crevices. Adults have no natural predators, and are thus labeled apex, or alpha predators. They can live for 20 years in the wild, and like many other bird species in captivity they can live much longer, up to perhaps 60 years.
