The roadrunner is more than just the comedic partner of the coyote, they are a very read animal native to the Southwestern desert and earned its name by running on the road towards cars. Roadrunners are a fairly large ground-dwelling birds, measuring 18-24 inches from beak to rail and weighing from 0.5 to 1.5 pounds. They are capable of flight, but still prefer to spend most of their time on the ground. Since they are able to run up to 20 miles per hour they prefer to spring instead of flying because they short wings are only able to keep them airborne for a few seconds at a time. Roadrunners are considered to be monogamous birds, with a male and female choosing to mate for life.
