An opossum in the snow

[I’m on the road this week and looking forward to seeing some snow! With that in mind, I decided to reprint this piece from 2010. A new NDN post is in the works for next week.]

A dusting of snow always makes it easier to see who’s been out and about in the neighborhood. Bird tracks don’t provide much insight into genus and species, but opossum tracks are recognizable enough. Several of them—or maybe it was one very busy guy or gal—live along a favorite walking route of mine.

example of opossum paw printsOpossums are down with life in and around town, in part because they are the penultimate omnivorous opportunists. In addition to their “traditional” cuisine, which features insects, small vertebrate animals, wild fruits (including persimmons, a special treat), and carrion, ‘possums are known to take advantage of uncovered garbage bins (not without risk, as they often fall in and become trapped) and bird feeder spillage. They’re not shy about venturing through a pet door now and then either, especially if there’s a beckoning bowl of kibble on the other side. This can come as quite a shock—to both parties—when the homeowner wanders into the mudroom or kitchen expecting to say good morning to Garfield or Odie.

If ever there was a creature in need of a good spin-doctor, it’s North America’s only marsupial. The Aussie cousins—kangaroos, wallabies, koalas, sugar gliders, even wombats—have somehow garnered a higher charismatic ranking than poor old Didelphis virginiana.

Their long snout, gray fur, and naked tail cause many city and suburb folks to mistake them for rodents, and this may be the root of their public relations problems. I remember a wildlife center phone conversation with a woman surprised and frightened by an opossum who wandered through the pet door into her laundry room.  Eventually, I was able to calm her down a bit by convincing her she was not dealing with a freak-of-nature rat, but my attempts to help her appreciate the natural beauty standing in front of her dryer fell on deaf ears.

Startled Woman: I’m sorry, but I can’t even stand to look at him… he’s just so UGLY!

Indignant Wildlife Biologist (that would be me): Well, ma’am, he’s probably thinking the same thing about you!

Not one of my finest Wildlife Hot-Line moments, I know, but the words were tumbling off of my tongue before I had a chance to bite it. I happen to find opossums quite handsome. Still, there’s no denying that rodent resemblance. If you are mouse-and-rat adverse you’ll probably never come to think of ‘possums as pretty.

There’s another problem—it’s a common misconception that ‘possums are clumsy, dirty, and not all that bright, with poor vision and hearing to boot.

Don’t believe it.

Personally, I think any species that’s managed to survive relatively unchanged since the Cretaceous deserves a little more credit. Modern humans arrived on the scene nearly 90 million years later, so perhaps we should be a little more respectful of our elders.

Opossums are actually quite clean. They carefully groom themselves during and after eating—even the babies. When it comes to the acuity of their senses, common knowledge has it all wrong. These marsupials have excellent hearing and can easily detect the rustling of prey hidden under dry leaves or tree bark. A wildlife rehabilitator friend who works extensively with opossums tells me they evolved with a focus on olfactory sensitivity and, as a result, have an extraordinary sense of smell. Their sight is about average for mammals, but because they are primarily nocturnal, their eyes are adapted to working under low-light conditions. Our daytime is their night and, as a result, they can appear rather dazed and confused in sunlight.

Kind of like me when I’m up past my bedtime.

You haul

eastern chipmunk

Moving supplies have been dominating my thoughts of late and taking over my apartment too. With boxes stacked everywhere the walls are, quite literally, closing in. When claustrophobic thoughts threatened this afternoon, I took a deep breath and remembered that wide, open spaces were waiting outside.

But a funny thing happened when I walked through my front door into a bigger world. I promptly fell into a smaller one.

I was sitting beneath a favorite shade tree, just letting my mind wander anywhere it wanted to go that didn’t involve packing, when my adventure began. Staring absently at the clover 6’ beyond my feet and growing sleepy, I wasn’t even startled when a pointy, soil-dusted nose suddenly pushed it’s way, dreamlike, to the surface. In short order the nose became an Eastern chipmunk (Tamias striatus), complete with rusty-brown face, two bright, black eyes, curious, mobile ears, small hands, and a slender torso. Of course, vertical stripes are always slimming.

Maybe I was large and still enough to be perceived as part of the tree. Perhaps a long to-do list was urging her on to the tune of “I’m late, I’m late, for a very important date!” Either way, that rodent paid no attention to me at all as she immediately set to work. I settled in to watch, sure I’d found the perfect distraction from my own busy schedule… but then she started packing.

No, she didn’t pull cardboard boxes and rolls of tape out of that hole in the ground. No need, when you’ve got a steamer trunk in each cheek. Okay, technically they’re pouches, but they are used to transport things from one place to another. Lots of things—this species has fewer molars than other chippies so there’s extra room. What do chipmunks need to carry? Some plant-based bedding now and then, but mostly groceries. During the summer their diet includes perishables such as wild fruits, bird eggs, insects, and other small creatures. These items are consumed immediately. Nuts and seeds are naturally long lasting, so they end up in underground caches. When you need both your arms and legs to get around, there aren’t any limbs left for lugging things to and fro. Ergo… you stuff your face.

Believe it or not, there are people who spend time documenting and reporting what chipmunks pack into these pouches, and we’re not talking small potatoes. Seriously—the pouches are big, but they’re not that big; an adult chipmunk is smaller than your average restaurant Idaho. The cheeks are large enough, however, to hold 70 black-oil sunflower seeds, 31 dried corn kernels, or 13 prune pits (where do chipmunks find prune pits I wonder… curiouser and curiouser).

As the small face in front of me grew wider, I began to doubt that it would fit back through a 2” opening without leaving behind some of the payload. I forgot that by this time of year, even a young’un would be an old hand at this. She dove into the entrance without a second’s hesitation… and me right on her heels, having conveniently shrunk down to chipmunk size (in my mind, that is—there weren’t any bottles labeled “Drink Me” at hand).

I’m not Alice and this was no rabbit hole, so we didn’t fall into a chasm. The whole burrow was only 18-36″ below the surface. She scampered along an 8’ tunnel towards a labyrinth of chambers and passageways, darting past what appeared to be a nesting area into the pantry; one of many pantries, actually, although technically, I think these rooms are referred to as hoards. From November through March or April, chippie chick and her kin will spend most of their time underground. If the weather above is warm enough, they’ll venture out to forage, especially if there’s a handy bird feeder nearby, but chipmunks rely primarily on foods put up during the summer months. Not a true hibernator, they arouse now and then from periods of torpor. When they do they need to eat, and there’s no cake in this Wonderland.

Or books, or dishes, or clothing, or any of the other myriad items waiting to be stuffed into the cartons I’m using instead of pouches. But my belongings won’t pack themselves and my new friend is busy taking care of her own business. “Time to leave Wonderland,” I thought, shifting ever so subtly. And with that, I was instantly transported back to my favorite tree, watching a tail tip disappear into a hole in the ground. Definitely time to return to the land of boxes and rental trucks… and cake!

When I head out for more supplies I think I’ll stop at the grocery store for a treat. This is one cake that doesn’t need to say “Eat Me.”  With all the bending and lifting and stair climbing I’ve done today, I can have a slice without fear of growing too large to fit in my apartment.

An opossum in the snow
