Good Natured: Chipmunks eat meat? The secret's out!

He might not be stronger than a locomotive, or able to leap tall buildings in a single bound. But somewhere out there in the DeKalb County countryside, there’s a chipmunk whose secret identity has finally been exposed.
He might not be stronger than a locomotive, or able to leap tall buildings in a single bound. But somewhere out there in the DeKalb County countryside, there’s a chipmunk whose secret identity has finally been exposed.

Secret identities. Our popular culture is full of them.

Daily Planet reporter Clark Kent takes off his glasses, dons a cape and then, faster than a speeding bullet, becomes super-strong Superman. Peter Parker, bitten by a radioactive spider, transforms into Spider-Man, complete with web-slinging superpowers and acute “spidey-senses.” Humble and lovable Shoeshine Boy morphs into Underdog whenever peril threatens his Sweet Polly Purebred.

Then there are chipmunks.

That’s right, the chippy. That oh-so-common eater of birdseed, grass seed and other bits of vegetable matter, has a secret identity I’ll bet many of you will find positively shocking.

Li’l ol’ Tamias striatus sometimes, when conditions are right, turns into a ... cue the kettle drums ...


An eater of meat.

I suppose this trait, to be most correct, would make chipmunks omnivores. That is, eaters of both plant and animal material.

But still, the sight of a cute-as-a-button Chip, or Dale, with flesh hanging from its jaws, blood dripping from its teeth, gives even the most seasoned naturalists reason to take a second look.

My friend Peggy Doty, who leads the team at Russell Woods Environmental Center in Genoa, recently had occasion to view such an astounding event. Even better, she had the presence of mind to take pictures.

It turns out chipmunks, and in fact most rodents, will supplement their plant-based diets with meaty proteins if and when the opportunity presents itself. It could be that a nest was left unguarded, and tiny, helpless hatchlings are suddenly free for the picking. Likewise for newborn mammals, should their parents leave them unattended.

Or maybe an adult animal has recently met its demise. A bird crashes into a window. A squirrel gets hit by a car.

In still other cases, chipmunks, as well as many of their rodent cousins, actually will kill prey – anything from juicy insects to adult birds, reptiles, amphibians and, sometimes, each other. (Can’t you just imagine Jerry Springer or Maury Povich getting ahold of this information? “Up next … the shocking footage of what REALLY happened to Alvin, Simon and Theodore ...”)

In chatting with Peggy, whose impressive resume includes a degree in wildlife biology, I learned the frog she observed being consumed most likely met with calamity before the chipmunk arrived on the scene. “Though it was very fresh, I believe he found it [already dead],” she said. “There was not a mark on the torso of the frog. My thought was that it would have been fighting back if grabbed by a leg or something.

“Unless ... he was a ninja chippy and snuck up from behind and snapped the frog’s neck. Wait, what neck? Ha!”

Besides being an ace naturalist, my dear friend also is very funny.

The series of photos Peggy sent includes shots of the chipmunk peeling the frog, stuffing the legs in his cheek pouches, and taking nibbles of other assorted body parts before ultimately leaving the limbless carcass on her door mat.

Then, just like that, he was gone. Perhaps he scampered off to digest his meaty meal in comfort and privacy. Or maybe he went over to Peggy’s bird feeders for a few seeds, or to the birdbath for an after-dinner drink.

We’ll never know whether he went back to being a mild-mannered herbivore, or if, fortified by proteins, he headed off in search of bigger and/or better prey. Wherever he ended up will just have to remain – like his penchant for meat – a well-kept secret.
