Great horned Owls mating calls

Great horned owls nest during the months of January and February. During mating season, male and female great horned owls hoot back and forth to each other in a duet. Their mating rituals also include bowing to each other and rubbing bills. When ready to nest, they do not build their own nest but instead seek out existing sites such as the nests of other birds, squirrel nests, tree holes, crevices in rocks and nooks in buildings. Some great horned owls mate for many years.

Clutch size varies with latitude, weather, and food supply, but generally, are two or three eggs. When prey is available, nesting begins earlier in the year; in leaner years, nesting is later and sometimes owls will not lay eggs during very poor years.
