Meep meep! Just like in the cartoons, roadrunners love to run and can reach speeds of up to 20 miles per hour. They can fly for short distances but prefer to remain on the ground where they hunt for prey. Cute in a goofy kind of way, roadrunners are very fierce predators. They will eat pretty much anything they can catch, including mice, lizards, scorpions, rattlesnakes and other birds. This one at Big Bend National Park in Texas grabbed this snake snack to present to a potential mate. How romantic! Photo by Lee Jaszlics (www.sharetheexperience.org).
