When humans talk about making a breakfast, lunch, or dinner run, it’s understood that we’re speaking metaphorically. Truth be told, we’ll probably drive, not jog, to a local café, convenience store, or Kroger. The same cannot be said about the way greater roadrunners (Geococcyx californianus) grab a meal. Fast food is how these long-legged, long-tailed, long-necked North American cuckoos roll—make that sprint—through life.
I mean that quite literally. Roadrunners are feeble fliers but they can definitely beat feet. Angling the body forward to nearly parallel with the ground as they pick up speed, the tail is held flat, acting as a stabilizer during turns. Their unmistakable X-shaped feet, with two toes pointing forward and two toes pointing backwards, are better suited to life on the run than the typical three-one toe formation of perching bird species. And who needs powerful wings when you can leap skyward, as if propelled by a pogo stick, to grab a snack out of thin air?
If you grew up in the U.S. during the latter half of the 20th century, as I did, you may have some serious misconceptions about this fleet-footed bird, not to mention coyotes (Canis latrans). For example, roadrunners are quick but at top speeds of 43 mph, coyotes are more than twice as fast. Smarter, too.
Moreover, I think Warner Brothers animator Chuck Jones must have grabbed the wrong field guide when he started to sketch, because his roadrunner looks more like an ostrich (Struthio camelus) to me than the iconic avian of the American Southwest. I think you’ll agree that a side-by-side line-up provides plenty of evidence to back up that statement.
Roadrunners do have at least one thing in common with ostriches—both birds prefer more arid, savannah-like landscapes to damp, dense forests. That said, greater roadrunners have been expanding their range, moving east from southern California, Arizona, New Mexico, and Texas, into the juniper, pine, and hardwood stands of Oklahoma, Missouri, Arkansas, and even Louisiana. And while they won’t tolerate densely populated urban areas they are showing up in more open suburban developments.
Like so many desert species, roadrunners have evolved to survive in a low rainfall environment. This includes a gland near each eye that secretes a highly concentrated salt solution, reducing the amount of water lost through their urinary tract. The ability to efficiently use the moisture present in their food reduces the roadrunners’ dependence on scarce surface water supplies.
I have a few more bones to pick with Warner Brothers’ depiction of the life and times of coyotes and roadrunners. For one thing, those cartoon characters would have you believe one is a predator, the other prey. Well, my friends, that’s as wrong-headed as expecting a tiny Acme parasol to protect you from a falling boulder.
The real skinny is that roadrunners are predators, too. Their moveable feast includes just about anything they can catch, including insects, spiders, scorpions, frogs, toads, songbirds, bats, rodents, and lizards. They’ll even pair up to take on a rattlesnake—one bird distracting the serpent, the other sneaking up from behind to pin the head down, rending those venom-delivering fangs moot.
This chick is all business. I’m not kidding.
Once their prey has been dispatched, roadrunners swallow their food whole, so there’s no need to carry around silverware, a la Wile E. Before that hummingbird goes down the hatch, though, there’s an important food prep step that has to take place. Fair warning—the process will make you reconsider the sincerity of that two-dimensional speedster’s goofy grin. I’ll let my friend, fellow wildlife enthusiast, and long-time Albuquerque resident, Janelle Harden, deliver the play-by-play:
“Not everyone would appreciate this, but I know you will! I saw a roadrunner catch a house finch on my driveway the other day. Holding the dead bird by the head, the roadrunner proceeded to bash and thrash the carcass against the concrete curb. Once the skeleton was pulverized and the body limp as an al dente noodle, the roadrunner threw her head in the air, along with the finch, opened her bill, and let gravity do its thing. It was fascinating! Took about 6-8 big swallows, and I swear her eyes got bigger with every gulp!”
I have to admit, I do appreciate Janelle’s field observations, and her description of the roadrunner’s bulging eyes does sounds pretty cartoonish. It’s the kind of thing I could imagine happening to a certain famously incompetent but persistent wild canid. Maybe Chuck Jones wasn’t a total Looney Tunes after all.
Gotta run—that’s all, folks!

Great post. Most informative, especially as my only exposure to this species is the Warner Brothers version.

Thanks! And yes, thanks to Warner Bros. the roadrunner is probably one of the best known, least understood and recognizable wild birds LOL
