The Great Horned Owl is one of the most widespread and common owls in North America. Here are some cool facts about this owl.
They use a variety of nest sites, including trees, cliffs, buildings, and the ground. And they don't make their own nests. They typically take over nests in trees made by other bird species. They often put nests in hollows or broken-off snags in trees.
The Great Horned Owl will take large prey, even other raptorial birds. It regularly kills and eats other owls, and is an important predator on nestling Ospreys. This interesting tidbit is the reason for this particular blog.
About two weeks ago I was yet again laying in my hammock (By the way, it may seem like I spend a lot of time in my hammock, but I really don't), and when we were putting the cover on it I noticed what looked to be a kill site. There were feathers everywhere. Red feathers, so I sent this picture and called my fellow expert birder San to see what she thought.

Once I examined the skull of this rather large bird I realized that it had to be a Red Tailed Hawk. So now that I knew what the prey was, it was easy to figure out who the predator was. In our area, other than humans, Hawk aren't really hunted by anything other than the Great Horned Owl.
Not a happy find, but I was glad I was able to find out what happened to this beautiful creature.
We just had a great horned owl perched on the peak of our roof. He hooted three times then flew off. I believe he was a adult because of his size and his horns prominent. It was just getting dark and my husband drove onto the driveway and heard the "Hoo Hoo Hoo" and thought someone was kidding around and then looked up and seen the Great Horned Owl and called us outside to see. We live in Calgary, AB, Canada close to the BowRiver.
