Title: Roadrunner
Content:  Roadrunners inhabit the Southwestern United States, to parts of Missouri, Arkansas, and Louisiana, as well as Mexico and Central America. They live in arid lowland or mountainous shrubland or woodland. They are non-migratory, staying in their breeding area year-round. The greater roadrunner is not currently considered threatened in the US, but is habitat-limited.
Title: Greater roadrunner
Content:  The greater roadrunner is found in the Aridoamerica ecoregion, within the southwestern United States and northern Mexico. It can be seen regularly in the US states of California, Arizona, New Mexico, Texas, Nevada, Utah, Colorado, and Oklahoma, and less frequently in Kansas, Louisiana, Arkansas, and Missouri, as well as the Mexican states of Baja California, Baja California Sur, Sonora, Sinaloa, Chihuahua, Durango, Jalisco, Coahuila, Zacatecas, Aguascalientes, Guanajuato, Michoacán, Querétaro, México, Puebla, Nuevo León, Tamaulipas, and San Luis Potosí. The species is not migratory. The greater roadrunner can be found from 60 m below sea level to 2300 m (rarely up to 3000 m). It occupies arid and semiarid scrubland, with scattered vegetation (typically less than 50% cover) with a height of less than 2 –.
Title: Lesser roadrunner
Content:  The lesser roadrunner occurs in arid lowlands of Mesoamerica up to 3,000 meters in altitude. It inhabits open ground areas, with scrub and thorny bushes. They can be found in higher elevations of stratovolcanoes such as Conchagua, San Miguel, Santa Ana and San Salvador, in semi-open areas above the treeline. They also adapt to cultivated land such as henequen and corn fields. Its breeding range is in southwestern Mexico, north into the western side of the Sierra Madre Occidental range, along with northern Central America and a disjunct range in the northern Yucatán Peninsula. It overlaps with the range of the greater roadrunner in a small area in the states of Sonora, Sinaloa, Jalisco, and Michoacán.
Title: Roadrunner
Content:  The roadrunners (genus Geococcyx), also known as chaparral birds or chaparral cocks, are two species of fast-running ground cuckoos with long tails and crests. They are found in the southwestern and south-central United States and Mexico, usually in the desert. Although capable of flight, roadrunners generally run away from predators. On the ground, some have been clocked at 20 mph while a few have also been clocked up to 27 mph.
Title: Greater roadrunner
Content:  Greater roadrunner fossils dating from the Holocene and Pleistocene have been found in California, New Mexico,  Texas, Arizona, and the Mexican state of Nuevo León. The oldest known fossil comes from a cave in New Mexico, estimated at an age of 33,500 years. In the La Brea Tar Pits, fragments from 25 greater roadrunner fossils have been found. Several other fossils are also known from Santa Barbara and Kern counties, as well as Northern Mexico. Prehistoric remains indicate that up until 8,000 years ago, the greater roadrunner was found in sparse forests rather than scrubby deserts; only later did it adapt to arid environments. Due to this, along with human transformation of the landscape, it has recently started to move northeast of its normal distribution. Sparse forests can be found in these parts, in an environment similar to the prehistoric North American Southwest.
Title: Palm Springs, California
Content:  The fauna of Palm Springs is mostly species adapted to desert, temperature extremes and to lack of moisture. It is located within the Nearctic faunistic realm in a region containing an assemblage of species similar to Northern Africa. Native fauna includes pronghorns, desert bighorn sheep, desert tortoise, kit fox, desert iguanas, horned lizards, chuckwalla, bobcats, mountain lions and Gila monsters. Other animals include ground squirrels, rock squirrels, porcupines, skunks, cactus mice, kangaroo rats, pocket gophers and raccoons. Desert birds here include the iconic roadrunner, which can run at speeds exceeding 15 mph. Other avifauna includes the ladder-backed woodpecker, flycatchers, elf owls, great horned owls, sparrow hawks and a variety of raptors. The Sonoran Desert 
Title: Greater roadrunner
Content:  The Greater Roadrunner can maintain a speed of 30 km per hour over long distances. While running, it places its head and its tail parallel to the ground, and uses its tail as a rudder to help change its direction. It prefers to run in open areas, such as roads, packed trails and dry riverbeds rather than dense vegetation. The roadrunner less often engages in flight. It hovers from a perch, such as a tree or a human construction. More rarely, it flies short distances of 4 or 5 m, between potential roosts.
Title: Greater roadrunner
Content:  The greater roadrunner (Geococcyx californianus) is a long-legged bird in the cuckoo family, Cuculidae, from the Aridoamerica region in the Southwestern United States and Mexico. The scientific name means "Californian earth-cuckoo". Along with the lesser roadrunner, it is one of two species in the genus Geococcyx. This roadrunner is also known as the chaparral cock, ground cuckoo, and snake killer.
Title: Desert kangaroo rat
Content:  The desert kangaroo rat is found in arid parts of southwestern North America, including Death Valley, the Great Basin, the Mojave Desert, and portions of the Sonoran Desert. Though kangaroo rats persist in a variety of soils, desert kangaroo rats live exclusively in areas with loose sand, often dune terrain. The places on this list constitute some of the most extreme deserts in the United States including Death Valley, which has the record for the hottest place on the continent.
Title: Lesser roadrunner
Content:  The lesser roadrunner can run up to 20 miles per hour (32 km per hour). It spends most of its time on the ground, running in open areas, along roads or under cover. and is capable of limited flight, perching in bushes or low trees. Roadrunners bask in the early morning, on a fence post or bush. They cock their tail and droop their wings, then turn their back towards the sun, raising the scapular feathers and exposing their black skin which absorbs heat. They may preen themselves as well. The bird's call is a series of soft "cooing", about one note per second, made three to seven times on a descending scale.

Question: where does a roadrunner live in the desert?
