Hooded Warbler

It's time for a bird on this blog, and today's featured feathered creature is a doozy. Of the 38 species of warblers that breed east of the Mississippi, few can compare to the Hooded Warbler in pure pizzaz. I suspect Hoodeds rank high in the overall stats of people's favorite warblers, and with good reason.

Today, I had the opportunity to spend about five hours tromping some rugged forested terrain in southeast Ohio with Kelly Williams-Sieg, who is studying several species of forest birds as part of PhD program research at Ohio University. We found plenty of Hooded Warblers, one of her target species. Part of Kelley's work involves close study of foraging birds in an effort to determine energy expenditure as it relates to feeding, so we were watching these gold and black stunners closely, and had some outstanding observations.

Few birds get birders excited like Hooded Warblers; just watch the crowd reaction at a place like the Magee Marsh Bird Trail if an obliging Hooded makes itself known to the masses. But they are very common breeders in the large forested tracts of the southern Ohio hill Country. We had perhaps a dozen today in a relatively small area, and at one point four males could be heard singing from the same spot.

This is prime turf for Hooded Warblers. Rich eastern deciduous forest; mature overstory canopy with dense shrubby understory. The warblers generally stay low, and even though they are often at eye level, Hoodeds are not the easiest birds to spot due to the thick vegetation that they inhabit. Supposedly, they have the largest eyes, proportionately, of any warbler, an adaptation to better see in the perennial gloom of their shady haunts.



I made this video of one of our birds from this morning; it shows a male Hooded Warbler strutting his stuff. Note the chronic tail wagging and pumping, a distinctive characteristic of this species. Each time he flicks and fans that tail, the large bold white spots flash like beacons. There's a reason for that; check the next video.



In this video, we see a male Hooded Warbler foraging in thick undergrowth. I think of their feeding strategy as a shock and awe style of hunting. Essentially, they are like small feathered bulls in an insect filled china shop, raging about and literally spooking bugs from their hiding spots with their rapid movements and bright tail flashes.

Watch an actively feeding Hooded Warbler, and it won't be long before you'll see it make a short sallie out to flycatch a winged insect that it probably spooked from hiding. Such as the moth above, which I also photographed today. I don't know the species and haven't had time to research it, but this moth certainly seems to be some sort of dead leaf mimic. That ploy probably works well, but should our raging yellow bull happen through, I'd about guarantee this moth would flush. And make another meal for the Hooded Warbler.

you're right--last weekend we happily watched a pair for about an hour foraging along Clear Creek rd in the early evening and after a long day of birding it was a great treat to end the day with them (will you little buggers sit still for a minute???)

Outstanding warbler shots!

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…
