Western Meadowlark

While in billiard table flat Wood County recently, I got the opportunity to drop by and check out a cooperative territorial Western Meadowlark. Not long ago, I blogged about Thirteen-lined Ground Squirrels and shared maps of that species and a few others. The squirrels and the others that I mentioned are examples of western prairie species that expanded eastward, probably during the hot, dry Xerothermic Period of approximately 5,000 years ago.

The Western Meadowlark belongs to that list of long ago prairie immigrants. This beautiful blackbird is quite rare in Ohio, with only a few reported each year. This is about as far east as they make it, too. Go west, and they become the common meadowlark once one reaches the Great Plains states.

Western Meadowlark gurgles his bubbly melody from a roadside wire amongst a sea of corn, beans, and wheat. Once, extensive prairies covered this part of Ohio, and that's the habitat this bird would have originally been associated with. Our original prairies were oceans of diversity, supporting incredibly rich plant life, scads of insects of all types, and all of the other animals that come with such ecological wonderlands.

In 1837, John Deere debuted his chisel plow, and all was quickly lost. Settlers soon discovered that once cut and furrowed, prairie turf grew some of the most robust crops in the world. Probably less than 1% of Ohio's original prairie remains, but prairie birds like this meadowlark still try and stake a claim where they can.


He sings! Although Western Meadowlarks are practically inseparable visually from our common Eastern Meadowlark for all practical purposes, their song is as different as night to day. Maybe it is because I am jaded, seeing as I hear Eastern Meadowlarks all of the time, but I find the Western's song richer and more pleasing to my ear.
It is amazing that early ornithologists ignored this one for so long. As early as 1805, Lewis of Lewis & Clark fame noted Western Meadowlarks on their journey west through the prairies, and knew they were something new. Others also recognized that this was a different beast from the Eastern Meadowlark, but it wasn't until 1844 that John James Audubon formally named it. In recognition of the bird's seemingly being snubbed by earlier explorers, Audubon named it Sturnella neglecta.

Sorry about the wind noise - this is the wide-open prairie, after all! - but in this vid the meadowlark issues some call notes. They, too, are vastly different than its eastern counterpart. Westerns often make a low Chuck call, and this curious whistled call. When heard at close range, as here, to me it sounds as if they are amplified through a cheap amplifier - the call is somewhat mechanical and surprisingly loud.
Fortunately, I think an increasing number of people are recognizing the folly of destroying so much of our former prairie. There have been some fairly large-scale restorations in recent years that have been very successful.

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…
