The larger birds of Sierra Vista are outstanding in terms of their colors and shapes. Arizona is a vast landscape of bold color, formations and piercing beauty. The southeastern corner is no exception. Isolated mountains called “Sky Islands” rise abruptly from the arid desert highlands, harbor a tremendous variety of plant and animal life and border the San Pedro Valley. The unique grassland of the valley is supported by the San Pedro River, which enters Arizona from Sonora, Mexico and flows north to join the Gila River. A significant percentage of American birders, if asked to choose their single favorite regional destination, would pick southeastern Arizona. Within a relatively small region here, you can find Sonoran Desert, oak woodland, high-elevation conifer forest, and riparian areas. The list of special species is long, but a few highlights are Montezuma Quail, Gray Hawk, Violet-crowned Hummingbird, Elegant Trogon, Arizona Woodpecker, Northern Beardless-Tyrannulet, Buff-breasted Flycatcher, Olive Warbler, Rufous-winged Sparrow, and Yellow-eyed Junco.
