Young Great Horned Owls I’ve been watching apparently are old enough to leave the nest, although they haven’t looked that way to me. The birds pictured are an adult and one of her owlets in their nest at Westwood Hills Nature Center. There were/are two chicks. One left the nest Tuesday. The photo was taken Wednesday morning. In one shot here the young bird is stretching a wing, making primary flight feathers visible (adult peering over wing). The feathers appear half developed or less. The pair of young owls I was watching in a nest near Long Lake left their nest seven days ago. They looked very similar to the one pictured. They know best, obviously.
