Their powerful eyesight and strong, sharp talons make them superb nocturnal birds of prey. Many owls are threatened by climate change and habitat destruction. The Global Owl Project identifies the most endangered owl species and campaigns for protection laws. We can encourage adults to use pesticides and insecticides that are least harmful to wildlife and erect owl boxes in the country to help them survive.
