Here's a photo of baby Great Horned Owls I took in Florida. They had moved out onto the branch from their nest. During the sixth to eighth week after they hatch, young Great Horned Owls leave the nest and may perch on nearby branches before taking their first flights. It can sometimes happen that the young leave the nest earlier because of a flimsy nest or other disturbance and in that case they may perch on the ground at the base of the tree and the parents bring them food. After the young fledge and can fly, they stay perched in the territory and wait for food to be brought to them. At nine to ten weeks of age they begin sustained flights and may follow after the parents and call loudly. They gradually develop their flying ability and learn how to hunt. At five months they are ready to live on their own and parents and young disperse off the territory. So cute at this age, then they grow up to be one of the fiercest avian predators in the woods.
