Altogether, over 450 species of birds have been documented within the borders of Big Bend National Park. That's nearly two-thirds of all the bird species found in the continental United States! What makes Big Bend National Park such a great place for birds? For one thing, the Big Bend region is on a major migratory route: the Central Flyway of North America. But why do so many birds land here? Why do some of them go no further south or north? And why do some of them not bother to migrate away at all? The answer to all these questions lies in the park's diversity of habitats. That is, the park has a wide selection of places where various kinds of birds can find shelter, water, food, and places to nest.
