This is an Eurasian Eagle Owl (Bubo bubo). It is an apex predator and thought to be the largest owl in the world.
Based on response I get to this podcast and to my bird photography, it's safe to say that people love raptors and particularly owls. (One exception is on the African Continent where most people think they are evil - but that's another podcast.)
The great horned owl (Bubo virginianus) is a successful hunter. Early naturalists called these owls "winged tigers" because of their ferocity. While rare, a great horned owl can occasionally catch and kill even a peregrine falcon! When clenched, a Great Horned Owl’s strong talons require a force of 28 pounds to open. The owls use this deadly grip to sever the spine of large prey.
This Eurasian eagle-owl (Bubo bubo) is one of my favorites. I love the pose. This is the largest owl in the world.
