Global Range: (20,000-200,000 square km (about 8000-80,000 square miles)) Several thousand years ago, California condors occurred over much of western North America, from British Columbia to northern Baja California, and they ranged eastward along the coast to Florida. Nesting occurred in western Texas, Arizona, and New Mexico until about 2,000 years ago, and condors inhabited the Pacific Northwest until the 1800s and northern Baja California until the early 1930s (Matthews and Moseley 1990). More recently, the species was restricted to southern California prior to extirpation from wild in 1987, when the last remaining wild condors were removed from the wild for captive breeding. Reintroductions in California, northern Arizona, and the Sierra San Pedro Martir in northern Baja California have led to very limited renewed nesting in each area. Some of the birds released in northern Arizona range into southern Utah and rarely as far north as southern Wyoming and Colorado.
Range extent (extent of occurrence) is roughly based on the regularly used nesting and foraging areas as of 2008.
