Nesting Season 2017
Great Horned Owls are back!

From Owl Research Institute on February 2, 2017:
The snow in Montana is getting deeper, the air still full of winter's bite. The Great Horned Owls have begun their annual demarcation of the seasons and in the next several weeks we will almost certainly find our first nest of the breeding season.

The Great Horned Owl, one of North America's largest owls, requires 11 to 12 weeks to go from a freshly laid egg to a flying owl. Even then, the young will remain close to the adults and beg for food throughout the summer and into the fall. The male and female, which have resided nearby throughout the year, have recently been spotted together around last years nest and can be heard hooting back and forth in the cold, dark night.

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.
