Cactus Ferruginous Pygmy Owl

The Center for Biological Diversity challenged the Federal Highway Administration over Interstate 11, citing its threat to endangered species like the cactus ferruginous pygmy owl. These tiny, fierce owls, weighing just 70 grams, are vital to the Sonoran Desert. Watch a video about them: Endangered Earth Online 1,224.
