Great Horned Owl
The great horned owl is the most powerful and widespread owl in the Americas, earning the nickname tiger of the sky. It is one of the earliest nesting birds, often laying eggs in January when snow still covers the ground. Great horned owls are fierce predators, regularly taking prey up to three times their own weight.
