This owl is ready for war! Great Horned Owl's are gorgeous, yet fierce predators that are never to be underestimated. Cunning and smart, owls are heavily built, barrel-shaped birds, and have large heads and broad wings. Like most owls, Great Horned Owls make great use of secrecy and stealth. Due to their natural-colored plumage, they are well camouflaged both while active at night and while roosting during the day.
