The great horned owls we have are huge. Saw two female chicks sitting on a lower branch about 6 feet away from me last spring and they were both about 3 feet tall. They appear much larger then the bald eagles around here. My dogs went nutso and they didn't even care. I wish I had my nice camera back then, because the old one didn't work. They tell us here not to leave <30 pound dogs run around loose, because the owls will kill them. I believe that. Have only seen the bald eagles in the air and not from up close. Anyway we have 5 breeding pairs of great horned owls on my property. I worry more about them then anything else. I even put up a temporary aviary for my ducks when they were young.
