Big Bend National Park
Big Bend is located in the Chihuahuan Desert, one of four major deserts in the United States. It may seem counterintuitive but there are more bird species here than almost anywhere else in the country. This is due to the wide variety of habitats, some of which are not desert-like at all, as well as its location along many migration routes.
