Curious…

This Eurasian Eagle Owl (Bubo bubo) was taken in the Highlands, though is not a native of this area, tending to be distributed sparsely through habitats as diverse as Northern coniferous forest to the edge of large deserts. Although rocky cliffs and mountains are favoured, eagle owls have even been observed living in European cities. The shot was taken through a line of trees and features both foreground and background blur. The Eurasion Eagle Owl is one of the largest owls with a wingspan of 138–200 cm (55–79 in) and measures 58–75 cm (23–30 in) long, and in the wild may live for 20 years. They feed mainly on small mammals such as voles and rats, mice and hares. Other birds are also taken including corvids (crows, magpies, etc), grouse, woodpeckers, ducks and geese and seabirds. The Eagle Owl is largely nocturnal and is usually found nesting on cliff ledges.
