The spring of 2019 I was graced with the appearance of a Juvenile Great Horned Owl on my front porch light. I heard a great commotion outside and I went out my front door and didn't see anything. As I turned to come in there he was just sitting in the middle of the afternoon on my porch light. Owls are nocturnal hunters, so it is rare for them to be out and about in mid day. He sat long enough to get my phone and come back out to take pictures of him, then when he was done posing for my pictures he flew away to the top of a giant maple tree.
The Great Horned Owl (Bubo virginianus), size 50-63 cm with a wingspan up to 1.4m or 4'7". They do not have horns but ear tufts which resemble horns, the juvenile does not have them. They have excellent hearing and are able to hear a mouse move beneath the snow.
Their wing feathers are ragged on the ends giving them a silent flight.
The Great Horned Owl prefers small to medium mammals, snakes, insects, ducks and other birds. Because he is known to be fearless and will kill skunks and porcupines he has a nickname of "flying tiger"

To this day I hear him who who whooing at dusk and into the night, I don't see him but I do know he's out there taking care of the mice and rabbits in my yard.
