SAN ANTONIO – A Castle Hills resident discovered a Great Horned Owl that was injured and in need of help about a month ago. Cuny said a rescue volunteer caught the owl that was brought to the Wildlife Rescue and Rehabilitation sanctuary in Kendalia. Since they are nocturnal hunters, the Great Horned Owl probably landed on a street or roadway to eat its prey, Cuny said. However, the rescued Great Horned Owl was spared the worst. The Great Horned Owl was returned to familiar territory for its release.
