Worm-eating Warbler

A gorgeous Worm-eating Warbler poses nicely in the understory of a wooded slope in Shawnee State Forest in southern Ohio. I spent the day in this place yesterday on a glorious spring day. The sun shone all day long, the mercury rose into the 70's F, and migratory birds had returned in droves.

Of all the warblers that breed in Shawnee, it's possible that the Worm-eating Warbler is my favorite. It's a subtle animal in every respect. They breed on steep heavily wooded slopes with a well-developed understory, and do much of their foraging in fairly dense growth. That, coupled with the often dim lighting of their haunts, can make "worm-eaters" tough to spot. While the males sing frequently, it's not an overwhelming song. Their tune is a dry, rapid husky trill, reminiscent of a Chipping Sparrow. This is an easy bird to pass right by, even though in a place like Shawnee, an intrepid traveler might be in proximity to 50 or more of the birds in a morning.

Right now is a great time to make a study of forest breeding birds. Many, such as the worm-eaters, have just returned and the males are quite busy trying to establish territories. This means much singing, and conspicuous battles with neighbors as turfs are set up. The bird in this photo was engaged in a serious sing-off with a nearby neighbor, and constantly visited a regular series of singing perches. All I had to do was sidle into a good spot, and watch the action.

A note on the name: the specific epithet vermivorum of the scientific name means "a worm". Hence the common name. It's naming harks back to a time when scientific descriptions were less than exacting, and caterpillars were often called worms. No self-respecting Worm-eating Warbler would probably actually eat a true worm - one of the "night-crawlers" - but they avidly consume the larvae of Lepidoptera - butterflies and moths (caterpillars). Worm-eaters are somewhat specialized foragers, spending much time gleaning through hanging clusters of dead leaves. Such sites are rich in invertebrate prey.

I continue to be disgusted by the treatment of Shawnee State Forest by its "managers", the Ohio Division of Forestry. This woodland belongs to all Ohioans, harbors some of the richest biodiversity in North America, and is being logged to smithereens. Enough is enough - this is not what most Ohioans want to see, nor is it good for the health of this magnificent woodland.

Hi Jim. I was in Shawnee yesterday also. Yes it was a splendid day. The same over logging (clear cutting) has been happening in Scioto Trails SF past few years. I have been visiting Scioto Trails 30 years (and Shawnee) and only last few has this over logging been happening. I hate to see my states beautiful forest treasures decimated. Is there someone in position in Columbus you can bring attention of this to look into. Gary Wayne. PS: i did not see Worm eater but did see lots else wildlife.

I remember going on several wildflower driving tours in Shawnee Forest many years ago. Some were close to the roadside while other wildflowers required a bit of a hike. They all were beautiful though and I still remember the fun we had searching. I hate to think that logging will take these experiences away from future generations. Shawnee is a special place.

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…

Ballooning spiders

Fear not, ye arachnophobes. The subject of this entry is indeed about spiders, but the star of the show is about as cute as a spider can get. And you'll want to know what we're about to learn...

On my recent West Virginia foray, we were strolling down a seldom-used lane, when a bright yellow object caught our eye. It was a goldenrod crab spider, Misumena vatia, on top of a post! Not only that, she - it is a girl - was acting extraordinarily goofy. The spider would stilt up as high as she could go on her legs, weave back and forth, jig side to side, and otherwise engage in what appeared to be spider break-dancing.

Click the pic for expansion, and you can see two columns of silk issuing from her spinnerets. This is an important point, as we set about determining what this non-web-making spider is doing.


So fixated was our spider on her task that she even rejected what would seem to me to be a perfectly scrumptious meal. This little caterpillar climbed rapidly up the post and dire…
