Here's a big hint:
This Great Horned Owl (Bubo virginianus) was perched on a Wax Myrtle branch near Campbell Cove on 8 September 2012.
Note the large size, the bright yellow eyes (see below), and the ear-tufts which give this owl its name. The ear-tufts looked a little small to me, and the throat wasn't bright white, making me wonder if this was a younger bird.
Great Horned Owls are "perch-and-pounce" predators. They often sight their prey from a perch. This owl was sitting quietly, but looked around and spent a lot of time staring down towards the ground.
