Join us at Sabino Canyon for an evening walk in celebration of World Migratory Bird Day! This year’s theme for WMBD is focused on light pollution and its effect on birds. Did you know that many birds migrate only during the night? Come discover why as we celebrate the night sky, and spring migration, look for nocturnal birds and reptiles, and enjoy the beauty of the Sonoran Desert on a warm evening! Fee required for parking ($8) at Sabino Canyon. Registration on Tucson Audubon Website required
