Riverside dragons and damsels

This weekend marked the annual Great Lakes Odonata Meeting, which was held right here in central Ohio. I attended Friday night's festivities, even giving a program on the Forest Giant, Megaloprepus caerulatus, the world's largest damselfly (7+ inch wingspan!). But I really wanted to spend more time in the field with all of the experts that were assembled, but other commitments wouldn't allow for it.

Inspired by Tom Arbour's outstanding photography in his presentation, I found a few hours late on Sunday afternoon to hit my local patch along the Scioto River and seek some dragons.

A large, lush patch of Water-willow, Justicia americana. An excellent habitat to slosh through seeking dragonflies and damselflies.

Exotic and orchidlike, the flowers of Water-willow are probably not all that often seen, as one typically has to get their feet wet to get at them.

I saw lots of these tiny beauties - Stream Bluets, Enallagma exsulans. If you are up for photographic challenges, try directing your lens towards dragonflies. They present several obstacles. One, they are possessed of outstanding vision and extraordinary flying ability. It is sometimes quite difficult to sneak within range. Two, they are long and narrow. It can be nearly impossible to get the entire critter in focus, so go for the eyes. Chances are if those are in focus the pic will be OK. Three, getting down on their level often means entering the water. I was kneeling in a couple of feet of water to work with these bluets.

A Powdered Dancer, Argia moesta. This is a very common streamside species, and is often found resting on rocks in the water or on logs and branches. Note how the wings are held well above the abdomen, a characteristic of dancers.

Face to face with a Blue-fronted Dancer, Argia apicalis. The thorax appears to be plated with turquoise armor.

One of our tiniest damselflies is this, the Eastern Forktail, Ischnura verticalis. This is an adult male, and the blue-tipped abdomen really stands out as they flutter weakly through the vegetation.

About as fresh a Common Whitetail, Plathemis lydia, as you'll ever see. This is a male, and it's not yet even mated. If it had, there would be telltale scars on the chalky-white abdomen where the female's legs would have rubbed off the pruinose covering during coupling. Whitetails nearly always perch prostrate on the ground, log, or rock.

Female Widow Skimmer, Libellula luctuosa, in typical repose. This species tends to perch low in rather dense herbaceous plan growth. Widow Skimmers are very common, and occur in all manner of wetland habitat, and are often found in meadows far from water.

Nice photos of damsels and dragons. It's so hard to remember them all.

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…
