The roadrunner is the official bird of which US state?

The greater roadrunner is a long-legged bird in the cuckoo family, Cuculidae, from Southwestern United States and Mexico. The Latin name means "Californian earth-cuckoo". Along with the lesser roadrunner, it is one of two species in the roadrunner genus Geococcyx. This roadrunner is also known as the Chaparral Cock, Ground Cuckoo, and Snake Killer.

This bird walks around rapidly, running down prey. It feeds mainly on small animals including insects, spiders (including black widows), tarantulas, scorpions, mice, small birds and especially lizards and small snakes. Venomous serpents, including small rattlesnakes, are readily consumed. It kills prey by holding the victim in its bill and slamming it repeatedly against the ground.

The roadrunner appeared in a 1982 sheet of 20-cent United States stamps showing 50 state birds and flowers, being the state bird of New Mexico. The state bird of Arizona is the Cactus wren, in California it's the California quail, while in Nevada the state bird is the Mountain bluebird.
