Greater Roadrunner With Prey.
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 c**k, ground cuckoo, and snake killer.
It's tall and is the largest cuckoo of the Americas. The upper body is mostly brown with black streaks and sometimes pink spots. The neck and upper breast are white or pale brown with dark brown streaks, and the belly is white. A crest of brown feathers sticks up on the head, and a bare patch of orange and blue skin lies behind each eye; the blue is replaced by white in adult males (except the blue adjacent to the eye), and the orange (to the rear) is often hidden by feathers. Males and females have identical plumage. Females are slightly smaller, on average 2 cm (3โ4 in) shorter and 30 g (1.1 oz) lighter than males. The long stout beak is grayish brown to gray and has a hooked tip. Roadrunners have four toes on each zygodactyl foot; two face forward, and two face backward. The toes are brown in color and have pale gold spots.
