Cuculidae or Greater Roadrunner Bird is a long-legged bird in the cuckoo family, Cuculidae, from the Southwestern United States and Mexico.

The scientific name means “Californian earth-cuckoo”. This roadrunner is also known as the chaparral cock, ground cuckoo, and snake killer.

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 and the orange is often hidden by feathers.

The vocalizations of the greater roadrunner have seven distinct variants. The most frequent call is a slow and descending sequence of about six low, cooing noises, emitted by the male and which is heard 820 feet away.

This call is usually made early in the morning, from a high perch such as a fence post, dead tree or cactus.

Cuculidae females give off a number of up to twenty-two short, low-frequency shrills, resembling coyote squeals, which can be heard 1,000 feet away.

Both male and female Cuculidae or roadrunners emit a series of five or six chatters accompanied by groaning, loud enough to be heard 700 feet away.
