The term "road runner" is generally used to describe birds that belong to the Geococcyx genus. However, there are several synonyms that can be used to refer to them. One of the most commonly used synonyms is "chapparal cock." This name is derived from the fact that these birds are often found in arid regions with chaparrals. They are also known as "Arizona ground cuckoo" and "ground roadrunner." Other synonyms for road runners include "cactus wrens," "ground cuckoos," and "long-legged roadrunners." Despite the name, road runners are capable of flying, but they are more commonly found running on the ground and darting between vegetation.
