Bubo bubo or Eurasian Eagle-Owl is a species of eagle owl resident in much of Europe and Asia. It is also one of the largest types of owls.The Eagle Owl is a large and powerful bird, smaller than the Golden Eagle. It mainly feeds on small mammals such as voles, rats, mice and hares.
The Eagle Owl is largely nocturnal and is usually found nesting on cliff ledges. Eagle Owls are distributed sparsely through a wide range of habitats. They have been found in habitats as diverse as Northern coniferous forests to the edge of vast deserts. Rocky areas seem to be favoured, with cliffs and mountains abutting woodland usually containing the largest numbers of these owls.
