Geococcyx

Description

The roadrunners (genus Geococcyx), also known as chaparral birds or chaparral cocks, are two species of fast-running ground cuckoos with long tails and crests. They are found in the southwestern and south-central United States and Mexico, usually in the desert. Some have been clocked at 20 miles per hour (32 km/h) while a few have also been clocked up to 27 miles per hour (43 km/h).
