Furry Spidermen

While out in the cool dark woods capturing Northern Saw-whet Owls a while back, we had an encounter with one of our more interesting animals. And one that is surprisingly common, although relatively few people have seen one.

If you are out in the woods at night, and very quiet, there are many animals to be heard. Quiet shuffling in the leaf litter gives away the little guys, like White-footed Mice, while louder clumsier shuffling might be a Virginia Opossum. Sometimes bloodcurdling screeches come from spatting raccoons.

But listen very quietly and you might hear a distinctive scrabbling of tiny feet on tree bark, coupled with chitters nearly inaudible to our ears. If you do hear this stuff, its likely to be foraging Southern Flying Squirrels, and that's what we encountered on our owl expedition. We heard the feet on bark, lit the tree up with the flashlight and there was the little guy, big eyes aglow. Like a circus trapeze artist, it put on quite a show for the group, racing high into the tree, darting from limb to limb with impossible speed and grace, and culminated his act with an impressive glide from the tree's summit out into the gloom beyond our pool of light.

These fuzzy little wack-jobs are something else. It's like someone took a quadripedal dwarf, covered him in fur, amped him up on Powershot and Espresso, applied superglue to the paws, then tied a bottle-rocket to his tail.

Off they go, roaring about the timber like maniacs. Hardly still for a second, and if multiple units are present short-lived battles are sure to ensue as Alphas and wanna-be Alphas duel for first place. The speed and sureness with which flying squirrels race about is nothing short of incredible, and what do they have to worry about? Falling? Not. A quick stretch of the appendages flaps open the patagial membranes, and you've got instant mammalian hang glider. They have been documented soaring for the length of a football field, and can even shift direction as they soar along.

No dummies, when a flying squirrel uses that beaverlike rudder of a tail to stall its airspeed and alight on a tree trunk, it promptly runs around to the other side. Good strategy and one no doubt learned the hard way as squirrels were sacrificed along the evolutionary trail to screech-owls who followed their flight plans.

Bob Placier, one of the owl banders, sent me a note reporting that a flying squirrel was recently caught in one of their nets. He reports that it was high-strung in the extreme, chittering and biting as they attempted extrication and only ensnaring itself even more. Eventually, they had to cut it free, thus liberating the big-eyed madman but essentially destroying the net in the process. Southern Flying Squirrel - 1. Owl Banders - 0.

If you've got decent-sized trees, even in suburbia, you've likely got flying squirrels. Wanna lure 'em in and watch the show? Slather Jiffy peanut butter up on a tree trunk, about as high as you can reach. Use the crunchy varieties; these are discerning little beasts and you don't want to make them mad.

I took the shots above at a friend's suburban feeding station, and it was a show, let me tell you that. Up to seven El Locos were in the tree at once, squeaking, chasing, combating, gliding, and grabbing Jiffy's finest until displaced by another beast, and every one of those scenarios generally took place in about three seconds per squirrel. They burn the calories, these boys.

But what a show.

Jiffy? I would think since they are flying squirrels they would prefer Peter Pan peanut butter! :)

Love these little guys! Am I right is saying, Jim, that they are our most numerous squirrels? I seem to remember that factoid from somewhere.

At my previous house in Clermont County, I flicked on the yard light one night to see something skitter around the backside of the tree, just departing my squirrel feeding station. At first I thought it was a rat, and I was grossed out. After some waiting and with judicious use of flashlights, I finally determined it was a flying squirrel. Totally cool!

I really miss those guys at this property. They are probably in the woods behind my pond, but I can no longer watch the nightly show, since this is former farmland with not enough older, large trees close to the house.

Thanks for the memories,

These furious little beasts are far too tough to utilize anything with the name "Peter Pan". They are the bigtime wrestlers of the miniscule mammal world.

And, yep, Katdoc, the people in the know claim that flying squirrels are likely the most numerous squirrel in these parts, which would no doubt surprise most people.

Oh, pipe down, Tinkerbell!

They are very hyper, but I think they are more like chihuahuas than The Undertaker. :)

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…
