Long Eared Owl by Simon and Karen Spavin: What a great shot! The erect ear tufts make it appear more imposing to other owls! --We were privileged to have a family of these owls in a pine woods near us one year.
The Eurasian Eagle-Owl is a very large, powerful bird, smaller than the Golden Eagle but larger than the Snowy Owl. It's often called the world's largest owl, tho the Blakiston's Fish Owl is slightly heavier and the Great Grey Owl is slightly longer.
