Winter Botanizing

Last Saturday was the Wooster Christmas Bird Count, organized by Roger Troutman. He's been at it a while, like 50 years or so. It's an interesting count circle, containing Killbuck and Funk Bottoms wildlife areas among other good bird-seeking spots.

My area included what is easily the most interesting botanical feature in the count circle, but hey, this isn't the Christmas Plant Count. Nonetheless, I made a point of walking through the swamp woods that buffer Brown's Lake Bog, and on into the bog. As any seasoned birder knows, you'll find more birds when you are out and about on foot, when all of your senses can come into play. In fact, just south of the bog, we were walking McFadden Road when I heard approaching geese. In addition to the Canadas, the high-pitched tinny calls of Cackling Geese rose from the pack, and moments later three of these pint-sized honkers passed over with a number of Canada Geese. They really sound different, and we would have never found them from the confines of an automobile.

On to the bog...

Brown's Lake Bog doesn't look like much in winter. This is the bog's core, with the deep pool of open water frozen over. A few thousand years ago, the open water would have been far more expansive. Over time, nature reclaims these kettle lakes with vegetation, and different plant communities form in concentric bands around the water. The outermost zones are swamp forest; inside of that are shrub zones; and ringing the water is the most interesting habitat, open bog mat.

Not a bog plant, but nonetheless interesting. We saw the old pods of this conspicuous plant nearby. It's Wild Cucumber, Echinocystis lobata. The spiny fruit are quite distinctive, as is its vining habitat.
Here's a true bog plant, Tawny Cottongrass, Eriophorum virginicum. Quite the rarity in Ohio, it is only found in bogs. The cotton candy-like tufts from the inflorescences persist well into winter, and one might argue that the plant looks at its best this time of year. Long, silky bristles attached to the achenes (seeds) create the showy tufts. The genus Eriophorum is quite northern; only two species occur this far south but there are plenty of them in the arctic.

To many plant enthusiasts, this is the creme de la creme of bog plants. Northern Pitcher-plant, Sarracenia purpurea, still looks good in the winter. The anthocyanins (colored pigments) in the leaves become bolder after the growing season, creating brilliant reddish-purple splashes amongst the soft lime-green beds of Sphagnum moss.

Straight down the gullet of a pitcher. This is a carnivorous plant, one of few true plant carnivores in Ohio. These modified leaves are effective traps, and enable the plant to capture insects; effective sources of nitrogen and protein. In the bottom of the leaf pools rainwater, injected with chemicals produced by the plant that reduce bouyancy and speed digestion. Basically, if you are a bug and fall in, it will be hard to float, and your soft parts won't last long. Those stiff, whitish hairs lining the throat are retrorsely directed; that is, they point down. That's great for the bug walking into the trap, but very bad for the bug that wises up and decides to bail. Quite hard going against those hairs, you know.
After the brief botanical interlude, it was back to tallying birds. We didn't find anything to top the Cackling Geese, but a Short-eared Owl was nice, as were two American Pipits.

Believe I may have encountered my first pitcher plant in NE Ohio. Would love to share the photo with you.

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…
