As a small child even into my early adult years, I didn't know that roadrunners were real. I watched as a kid and my older son watched as a small child, The Wiley Coyote cartoon where he is always trying to chase and capture the Roadrunner (but the Roadrunner always out smarts him).
Then in 2010, my husband and I traveled to Tucson Arizona to visit two of his sisters who live there. While there, I realized Roadrunners were real birds who really do live in the desert. Since both sisters lived in the desert, they were looking out for them to show us. They did point one out at one time from a distance which was cool. I went to a gift shop there and found a small Roadrunner trinket which I bought and display today.
After we got home from that trip, I looked Roadrunners up on the internet and learned a few things. They are a part of the Cuckoo family and there are two species, the Greater Roadrunner and the Lesser Roadrunner. The Greater Roadrunner lives in the desert South West of America and is bigger than the Lesser one. It is called a snake killer because it kills and eats snakes even poisonous ones among other creatures. It has limited flight but can run up to 20 miles per hour. The Lesser Roadrunner lives in Mexico and Central America. It is smaller than the Greater Raodrunner and eats small snakes, fruit, frogs and road kill.
