In the famous old cartoon, an incompetent and startlingly emaciated Wile E. Coyote tests his destructibility while in pursuit of the quick and clever Roadrunner. While the Coyote casts a menacing, if ultimately harmless figure, the Roadrunner is a gentle, aloof creature who wants nothing more than to run fast and eat seeds along a saguaro-speckled highway.

Those cartoons were silly fun. Like many people, I even felt that after a while the Coyote really deserved to catch the Roadrunner. But thinkin on it now, it seems like in all the craziness of that show, the Roadrunner's characterization as gentle is perhaps the most unbelievable aspect.

I love Roadrunners. They're big, beautiful, iconic desert birds, and it's truly jaw-dropping every time I see them out and about, even though they're fairly common. They've got cool looking feet and are perhaps the only birds that come with built-in racing stripes! That being said, the Roadrunners I've observed around Arizona are themselves much more ruthless and determined predators than our scraggly coyotes.

Roadrunners are successful predators because they're not too picky. As any bird book will mention, they eat bugs, small reptiles, rodents, birds, and even fruit if they must. Normally I wouldn't think of a bird from the cuckoo family as a vicious killer, nor even a meat-eater for that matter. Now, imagining a Roadrunner eating bugs of lizards seems appropriate, even familiar. I've had the pleasure of observing exactly this sort of feeding behavior from time to time.

Here a male Roadrunner--identified as a male by the blue and orange in his eye stripe--proudly poses with his cold-blooded kill.

I associate certain bird groups as eating certain things. I read that familiar caption, "eats small rodents, birds..." and usually don't think much of it. For the longest time, it almost struck me as a sort of disclaimer, just in case one crazy Roadrunner breaks free from the bug & lizard racket to go after a mouse. I guess I never really believed it because I had never seen it. Hawks, Falcons, Owls...those are the birds that eat other birds, that eat mammals. They've got talons and hooked beaks; they're built for it. Lots of birds eat bugs, and plenty will go for reptiles if given the chance. Without any experience to the contrary, I had just lumped Roadrunners in that group as well.  Recently I was confronted with the blunt, graphic reality that Roadrunners really are thoroughly predacious birds, that they do catch warm blooded creatures, and that they'll tear them apart.

This Roadrunner, a stout beast-of-a-bird pushing twenty-four inches in length, caught what I believe to be a young House Finch along a perimeter fence at the Desert Botanical Gardens. It carried its quarry to a little sunny patch of dried palo verde needles, and then began to disassemble its meal.

The Roadrunner has neither gripping talons nor an exceptionally strong sharp beak. While pressing his long tail against the fence to sturdy himself, he thrashed his prey back and forth, back and forth, working the edibles loose until he could swallow them in manageable chunks.

Raptors can catch, kill, and eat their warm-blooded prey with efficiency and precision. Raptors are really good at what they do. While the Roadrunner is usually a graceful, dexterous creature, here it resorted to blunt force, to wild motion, as it tasted blood. He was determined, but unlike the raptors, seemed out of his element.

Roadrunner Rex was very focused on his grisly task and paid me little heed, even as I struggled to fit both the Roadrunner and the Finch into the frame. The feast was up close and and personal, shocking and transfixing to observe...
I don't really know how to explain it. There was just something so disordered about this scene, and not just because of the guts and gore. Looking at a Roadrunner's cool and unique anatomy, even knowing the expert analysis, it just doesn't seem like this kind of graduated predator...and yet here was the proof, staring me red in the face.
This is more the image I'm used to seeing: a composed, colorful bird with a keen eye for the next little meal that might scuttle across its path.

But there is another side to the Greater Roadrunner. This side is seldom seen, though not because of shyness. It's not the side of the Roadrunner that we see in Saturday morning cartoons or even in many quintessential Roadrunner photos.

I guess it's the same harsh realization we come to with many other wild animals. Just when we think they're tame, they rebel. Just when we think the Roadrunner will zig, it zags. In the end, I know no more about this intriguing bird or how to predict its behavior than Wile E. Coyote.

Turkey Vulture

A common and recognizable sight across North America, the Turkey Vulture is the dingy janitor of the bird world. Although nearly eagle-size, their body is a non-descript black built only to glide, with no real muscular capacity to exert much force or move incisively. However, the overlapping thick flesh on their heads does provide a protection against the bacteria they encounter while feeding on over-ripe carrion, which does give vultures a certain (ugliness) specialness of their own.
