Big Bend National Park encompasses 801,163 acres, an area of magnificent contrasts. More than 430 bird species have been identified, more than at any other national park. Birds include the personable roadrunner, the raucous gray-breasted jay, beautiful hummingbirds, and the rare Colima warbler whose only U.S. nesting grounds are in the Chicos Mountains. Over 1,100 plant types are found in the park. Animal life is just as varied. Desert wildlife is mostly nocturnal, but deer, coyotes, javelinas, gray fox, skunks, raccoons, and jackrabbits might be seen during the day. Lucky visitors might spot some of the rarer animals, such as ring tail, black bear, beaver, and mountain lion. A permit is required for all back country and primitive camping; also for all river-users. Free permits may be obtained at Park Headquarters or ranger stations.
