Okay, they're just babies, but their parents were clearly great horned owls!
My guide explained Swainson's Hawks built and used this stick nest the last two years, but the owls beat them to it this year. I believe the second photograph features the head of an owlet peeking over the edge of the nest.
The Great Horned Owl, (Bubo virginianus), also known as the Tiger Owl, is a large owl native to the Americas. It is an adaptable bird with a vast range and is the most widely distributed true owl in the Americas.
