A powerful and adaptable bird of prey, the Great Horned Owl has the most extensive range, the widest prey base and the most variable nesting sites of any American owl.
Great Horned Owls lay 1-4 eggs, but in this nest in Charlo, Montana, 2-3 eggs is most common. The eggs typically hatch about 2 days apart.
Great Horned Owl chicks will stay in the nest for the first several weeks. By June, at 7 weeks of age, the owlets will be capable of short flights. Fledglings remain with parents for most of the summer.
