Nature: Known for fur, minks are voracious predators

An American mink in Battelle Darby Creek Metro Park

The American Fur Co. was founded in 1808, and for a brief time in the 1830s, it was one of America’s largest companies. Its success made its founder, John Jacob Astor, the first multimillionaire in the United States.

Although demand for beaver pelts drove much of the American Fur Co.’s business, other mammals were vital to its success, especially the American mink. As the easier-to-trap beaver became increasingly rare, the mink became more important to trappers.

Between 1820 and 1900, the American Fur Co., Hudson’s Bay Co. and other fur purveyors sold about 12.5 million mink pelts.

Fortunately, these large weasels survived the days of indiscriminate trapping and are common today. But they are often wary, largely nocturnal and usually difficult to observe in the wild.

I recently visited Battelle Darby Creek Metro Park to photograph birds, arriving around dawn. I was not long into a grassy trail that weaved through a marsh when who should come bounding down the path? A mink!

Like a semi-psychotic mammalian Slinky, the mink romped along the trail, moving rapidly in exaggerated, undulating bounds.

When it got within 20 feet of my position, the hunter finally noticed me and careened into the cattails, but not before I took a series of photos in the dim light.

Mink belong to the Mustelidae family, which includes weasels and otters. Of Ohio’s regularly occurring mustelids, only the river otter is larger. A big male mink — males are 15 to 20 percent larger than females — can measure 2 1/2 feet from nose to tail tip. It might weigh nearly 3 pounds.

While a 3-pound mammal might not seem like much, in the case of the mink, it’s Genghis Khan, Jack the Ripper and Attila the Hun rolled into a well-furred, tubular package. Just ask a muskrat. Even though these aquatic rodents can significantly outweigh a mink, they often fall prey to the voracious predators.

Streams and wetlands are the bailiwicks of mink. The animals play an important role in the food chain, taking fish, amphibians, small mammals, birds and other such fare. Would-be victims are in a tough spot if they land in the sights of a hungry mink, which has speed and the ability to swim and even climb trees.

Few predators will attempt to take a mink, although coyotes and great horned owls might try.

A mink that finds itself among prey aplenty adopts a kill-and-cache strategy. It’ll dispatch everything it can and attempt to hide the uneaten victims. On occasion, the owner of a poorly secured chicken coop learns about mink killing frenzies.

Come early spring, minks become amorous. As befits such a savage animal, the mating process is not lovey-dovey. The male seizes the female, pins her and often bites her neck and head. After she’s survived that rough romance, she’ll deliver four or five pups in an underground burrow.

Humans who act like minks are likely to be institutionalized, and good thing. But we have nothing to fear from these fascinating beasts, although we can be grateful they’re not the size of bears.

I remember seeing a mink crossing a road with a big frog in it's mouth. It stopped to stare at us for just a minute but that minute was seared into my memory. How I wish I had a camera at that moment. I probably would have been too awestruck to do anything with the camera anyway.

Many sightings around Massillon,OH Resevoir Park set in small town residential properties. Once saw a hilarious Facebook posting this spring after several rainsoaked days...with closeup head shots, posting read: hey, has anybody lost their pet ferret? Adorable and so friendly, he came right up to us for a petting...eventually,folks clued her in and, instead of simply opening the garage for Mr. Mink's return home after H2O levels dropped...the self proclaimed (and uneducated) neighborhood naturalist folks insisted that the poor guy be relocated to another wildlife center 5 miles if he didn't belong here! Hoping he quickly jumped into Sippo Creek for a ride downstream and back home.

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
