It is worth noting that the equivalent ecological niche in North America is occupied by the roadrunner (Geococcyx
californianus), a member of the cuckoo order (Cuculliformes).
Cameras recorded kit fox (Vulpes macrotis), coyote, common raven, and greater roadrunner (Geococcyx
californianus) scavenging 10 of the carcasses (Fig.
All species were classified into one of five categories: (1) western: species that occur predominantly west of about 98[degrees] west longitude (e.g., roadrunner Geococcyx
californianus), (2) central: species that are predominantly in the central plains area (e.g., Great Plains narrow-mouthed toad Gastrophryne olivacea), (3) widespread: species that occur in virtually all states and provinces in North America north of Mexico (e.g., pied-billed grebe Podilymbus podiceps), (4) eastern-western: species that are not widespread but which occur in both the east and in the west (e.g., Mexican freetail bat Tadarida brasiliensis), (5) eastern: species that are exclusively or predominantly found in the east (e.g., alligator Alligator mississippiensis).
At the same time, despite its dangerous venom, it is vulnerable to its own specific predators such as the roadrunner (Geococcyx
With the exception of the greater roadrunner (Geococcyx
californianus), every species that was found in scat from bobcats also was found in scat from ocelots.
During 2008 we identified a greater roadrunner (Geococcyx
californianus) nest based on dimensions; this species was not in the dichotomous key (Dunkin, 2008).
They are commonly preyed upon by roadrunners (Geococcyx
californianus), long-nose leopard lizards (Gambelia wislizenii), and a number of snakes including the western coachwhip, (Masticophis flagellum), striped whipsnake (M.
In the Chihuahua Desert, there are many birds, including the roadrunner (Geococcyx
californianus), the American kestrel (Falco sparverius), the lark bunting (Calamospiza melanocorys), ladder-backed woodpecker (Picoides scalaris), the cactus wren (Campylorhynchus brunneicapillus), and some larger desert birds such as the turkey vulture or turkey buzzard (Cathartes aura).
