A male Anna's Hummingbird is a striking sight, known for its vibrant gorget and forehead colors. This species can be found year-round in the Western United States. It is particularly famous for its impressive mating dives, which can exceed 100 feet (35 meters). Originally, Anna's Hummingbird occurred only in Northern Baja California, but it has since dramatically expanded its range. Today, it can be found along the West Coast up to Southern British Columbia and has also spread southeast into Arizona and, to a lesser extent, Texas. This significant range expansion over roughly a century is attributed to human population growth, which has brought cultivars and hummingbird feeders that support their existence. This species also has an ability to greatly slow its metabolism during cold periods to help it survive in the winter. Unlike other U.S. hummingbird species, Anna’s Hummingbird does not migrate latitudinally.
