The Bog, the Swamp and the Dawn of Spring

WILDER SIDE OF OAKLAND COUNTY

In these warming, waning days of winter, signs of spring’s approach are everywhere, but she leaves her most obvious door-knocking notices near our bogs and swamps. Henry David Thoreau wrote His soft warble melts in the ear, as the snow is melting in the valleys around. The bluebird comes and with his warble drills the ice and sets free the rivers and ponds and frozen grounds.”  Those words are true today: the eastern bluebird flits above meadows of crusty snow and perches on branches and old fence posts at the edges of swamps on the wilder side of Oakland County. At this very moment, something seemingly odd and other worldly is happening in our swamps. It’s an event that always seems to occur just as the warble of bluebirds sweetens the day.

As creeks babble and splash over glacially polished pebbles and ice crackles along the shores of swamps, one of our first flowering plants emerges during the final weeks of winter. Just before spring officially arrives, we can view the emergence of skunk cabbage. This strangely wonderful and oddly beautiful plant gets its name from the slightly putrid smell that comes if its leaves are crushed. It is not a coincidence that skunk cabbage seems to poke up through the ice at the edge of swamps, bogs and creeks as the plant warms its own micro-environment to 30 degrees or higher above the surrounding temperature. Skunk cabbage, a plant that always wants its roots deep in mud, is often referred to as a warm-blooded plant. That is not so far from the truth, as the snow and ice melting ability of skunk cabbage is legendary to botanists. This harbinger of spring actually creates its own heat through a process known as thermogenesis, a process that is almost exclusively in the domain of animals.

At the edge of the very same skunk cabbage habitat, a keen-eyed observer of nature may spot bluebirds overwintering here as well. Contrary to range maps that proclaim bluebirds as migratory in Michigan, many eastern bluebirds overwinter at the edges of bogs and swamps, areas rich with tiny fruits, seeds, and their primary food source – insects. And now, as the hours of daylight lengthen and the great melting of snow continues, bluebirds seek out nesting cavities in stumps and hollow trees near meadows that embrace the swamps edge. These habitats can be found in many of the 13 Oakland County Parks.

As the duel between winter and spring accelerates and softens the landscape, hikers will be rewarded by both the song of bluebirds and the sight of skunk cabbage along many Oakland County Parks’ trails. Specifically, any trail meandering near wetlands at Independence Oaks and Waterford Oaks, all the trails of Highland and Rose Oaks, The Buhl Lake Trail of Addison Oaks, and the aptly named Bluebird Trail of Orion Oaks County Park.

Scent of Love Spices the Air: Romancing the Skunk

6 Mar

WILDER SIDE OF OAKLAND COUNTY

Courtship is well underway for Mephitis mephitis, the often maligned striped skunk. That means the scent of love is in the night air. Romance for the skunk is a simple affair: wander about under the cover of darkness and search for a suitable mate. Yet, during these nocturnal searches, as winter slowly wanes, skunks may encounter other critters of the night: raccoons, coyotes, fox, cats and dogs. If these creatures do not give the hormonal-driven skunk, with a mission of mating on its mind, a wide berth, the skunk swings into defensive mode. First comes a warning: the front paws pound up and down. Perhaps that message serves to say, “Do you remember me from last time?”

The Red-Crested, Tree-Whacker of Oakland County

A male Pileated with a noticeable red cheek stripe creates a cavity to search out insects.

Pileated Woodpeckers are the loudest and most striking forest birds in the woodlands of Oakland County. They are also the largest woodpecker species to be found in North America, with the exception of the Ivory Billed Woodpecker: a magnificent bird that once haunted the southern swamps of the United States and forests of Cuba. Sadly, most ornithologists believe that the Ivory Billed is now extinct due to habitat destruction. In 2004, the Cornell Lab of Ornithology and The Nature Conservancy put a team together to investigate a dramatic sighting of an Ivory Billed Woodpecker in the Cache River National Wildlife Refuge in Arkansas. Their findings remained inconclusive but leaned toward credibility; the Ivory-Billed Woodpecker remains the Holy Grail of ornithology. Continue reading

Barred Owls: Ghostly Voice of the Swamp

20 Feb

WILDER SIDE OF OAKLAND COUNTY

IMG_9820

“Who cooks for you? Who cooks for you-all?” That’s the classic ghostly call of the Barred Owl, an owl very much at home in Oakland County. The rising and falling melody with a hint of a southern drawl in the last few syllables reminds naturalists that the owl’s breeding season is here. Yet, others less admiring of the raucous chorus of barred owls hooting back and forth may describe the sounds as the music of a troop of rowdy monkeys. That description  is very close to the truth.

Follow the Cornell Lab of Ornithology link to hear the calls of barred owls: http://www.allaboutbirds.org/guide/barred_owl/sounds 

Every now and then, a hiker might hear or even see a barred owl perched on a tree limb in daylight. Oakland County Parks, Huron-Clinton Metroparks and the State Recreation Areas of the Michigan Department of Natural Resources (located in Oakland County) all host these beautiful raptors of the night. Barred owls favor wooded wetlands with nearby open areas for hunting; that means trailside swaths of Addison Oaks, Highland Oaks, Independence Oaks, Lyon Oaks, Rose Oaks and Springfield Oaks county parks are perfect barred owl habitats.

NIGHT MOVES: Wildlife Selfies on Hidden Camera

12 Feb

WILDER SIDE OF OAKLAND COUNTY

When many of us think about nature and wildlife, our thoughts drift to faraway places. However, Oakland County remains surprisingly rich with wildlife. Even with increased urbanization and a loss of biodiversity accelerated by human actions, wild animals are abundant in parks, trails, greenways, and even have the freedom to wander our cities, villages, and townships. One might say their wild spirit leads them, but in reality, it is their endless search for prey.

MOULTRIE DIGITAL GAME CAMERA

Despite the fact that we live in the midst of a vast array of wildlife, it’s not easy to get a true glimpse into their daily lives. By using hidden cameras, we can observe wildlife in their natural habitat and view a true representation of their day and nighttime behaviors. Three species are standouts when it comes to being captured by motion-activated camera traps: the red fox, the white-tailed deer and the eastern coyote. Their stealthy night moves, caught on camera, give us a glimpse as they are, not as our minds imagine them. Continue reading

Wildlife Adventure Stories in the Snow

The eastern coyote is seldom seen, but tracks tell the winter tale of its wandering.

Winter is the perfect time to search for some of the most elusive creatures of Oakland County, especially nocturnal mammals and those species that struggle to avoid human contact. If you think there isn’t much to discover in the dead of winter in the Oakland County Parks, it’s time to think again. Tracks and trails in the snow are clues akin to those scattered about in a good detective novel. Sometimes the tracks and trails leave one with a shock and awe feeling, perhaps wondering, “What happened here?”

MUSKRATS: Masters of the Murky Marsh

WILDER SIDE OF OAKLAND COUNTY

With a bit of imagination, the common muskrat might be compared to a very large field mouse: one with a can do attitude that easily adapts to life in the wetlands and waterways of Oakland County. To muskrats, winter is not an obstacle for cozy living. For just like beavers, the muskrat prepares, with a few additional twists of its own, to guarantee Homeland Security during winter. This paunchy appearing rodent is covered with a rich, dark brown waterproof layer of fur (except on its scaly-skin tail). As soon as ice coats the lakes of the Oakland County Parks, the well dressed for the weather muskrats create pushups. Pushups provide a unique way for them to feed, travel and stay out of sight.
