The Opossum: Our Marvelous Marsupial


I’ve always had an infectious sense of wonder when it comes to close encounters with wildlife, but sometimes the very best encounters are totally unexpected, and it’s often with creatures that never seem to make anyone’s “must-see” list.

It was an unusually warm, snowless winter day at the end of January. I had just sprawled out on the ground with my camera resting on a fallen tree to position it for the best angle to photograph a beaver lodge at the edge of a secluded cedar swamp. Slight rustling in the dry leaves drew my attention. I turned to my left and an inquisitive young opossum was just a few feet away—not playing dead, not backing off, and not advancing. It watched me ever so intently as we both moved slightly about for better views of each other. The opossum inched closer and then we were eye to eye. It seemed to freeze in place. So did I.

The Virginia Opossum: Oakland County’s Mysterious Marsupial


What animal lived during the age of the dinosaurs, gives birth 13 days after a honeymoon, has thumbs on their hind feet and is falsely accused of being, a big ugly rat? If you guessed Didelphis virginiana, the Virginia opossum, you are right. The opossum is the only marsupial found in North America; Oakland County is home for hundreds, if not thousands of these amazing omnivores. The Virginia Opossum has fifty teeth (the most of any mammal) and feeds on almost anything and everything. They will hunt, kill and eat mice and rats and relish rotting road kill and crunchy cockroaches. Bird eggs, berries, beetles, frogs, fish and fruits of all sorts are also on the delicacy list. Don’t forget to add snakes, slugs and snails too. To put it simply, if it produces a scent, the opossum will eat it. Continue reading

March of the Marsupial!

Wilder Side of Oakland County

3209Breeding season is risky. To find a mate Didelphis virginiana must scurry across open fields, cross busy highways and negotiate tortuous creek banks flanked with slippery ice in a world full of predators.  Cars, owls, hawks, raccoons, coyotes, fox and domestic dogs all take their toll.  And then, just 12 days after a hastily arranged honeymoon 12 – 20 helpless babies no bigger than honey bees must attempt a difficult fur-clinging climb from the birth canal to the pouch and struggle for the 13 teats as mom waddles about in her solitary ways.  If more than 13 are born to this amazing creature with 50 teeth and a prehensile tail they will not survive.  This is not a creature of myth.  This is the Virginia opossum, a species that thrives close to homes in Oakland County and is found in every Oakland County Park.

3177Opossums are not   ‘big rats’.  They are not even rodents.   They are marsupials (pouched mammals), and one of their closest cousins is the kangaroo.   Opossums have stalked the earth for 70 million years and are the only marsupial found in Michigan.  Hollow trees, abandoned woodchuck burrows, the underside of suburban decks or even abandoned dog houses are perfect den sites.

3214Many suffered from frost bite and others perished in winter; their tails, ears and toes are all furless.  But for those that survived until spring, the county transformed into a world of plenty.  As omnivores they eat anything they find or can kill; the list is long and includes bugs, beetles, berries, worms, bird eggs, fruits, snakes, frogs and road kill. Road kill consumption is a dangerous practice for when frightened opossums freeze in place or flop over flat adding themselves to the roadside collection of entrees.  Although chiefly nocturnal, during the early days of spring warmth they are sometimes seen grubbing about under bird feeders or meandering on still snow covered but sunny trails.
