I know this is a very old observation...but owls used to nest in our yard every year. 2005 was the last, and I have not seen one here since.
Stone Creek, East Yorks, May 2009
No pics, but I saw it and I heard it. It was cruising around the canyon hooting at us.
Barn-owls (family Tytonidae) are one of the two families of owls, the other being the true owls, Strigidae. They are medium to large sized owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from Strigidae in structural details relating in particular to the sternum and feet.
