Yellow Warbler

High time a bird showed up here; I was thinking I'd have to change the blog's name to Ohio Insects and Biodiversity. And we'll go with a charmer, a warbler that ranks high among many birder's favorites, I am sure.

One of the "problems" of being an inveterate traveler that nearly always has a camera slung around his neck is that finding blog material is never a problem. In fact, I can never put anywhere near all the stuff that I, at least, find cool on here. I took the following shots back on May 23 at Magee Marsh Wildlife Area, and have intended to stick 'em up here ever since.

Luminescent lemon beacon of a bird, a male Yellow Warbler takes a breather in between spirited renditions of Sweet Sweet Sweet I'm So Sweet songs. Although this, along with the Common Yellowthroat, is Ohio's most common and widespread breeding warbler, it is still a fascinating bird. This one is perched in a fine specimen of Sandbar Willow, Salix exigua, and Yellow Warblers seem happiest when in damp soggy places populated with plenty of willows.

There are plenty of warblers that have yellow on them. This one is most deserving of having "yellow" as an official part of its name, though. No other warbler is so boldly sun-splashed as this one is, and the males are beautifully set off with chestnut streaking down the front. The scientific name is Dendroica petechia; the first part meaning "tree lover". Petechia is a commonly used medical term referring to reddish or purplish spots on the body, typically caused by minor hemorrhaging of capillary blood vessels. I guess the Yellow Warbler reminded Linnaeus of this malady when he named the critter back in 1766.

Yellow Warbler nest, probably that of the bloke in the previous shot. A finely woven and intricately sculptured cup indeed. Unfortunately, the lovely couple chose to site it in a shrub of Morrow's Honeysuckle, Lonicera morrowii, one of our worst offenders in the non-native plant department.

We have eggs, and GOOD NEWS! All look to be Yellow Warbler eggs. This species is heavily parasitized by Brown-headed Cowbirds, but, the warbler is much more clever than most. It is one of relatively few birds that can recognize cowbird eggs, and take action. Sometimes they'll just up and leave; in other cases the warblers will construct a new nest right on top of the one containing the cowbird egg. I remember seeing a photo somewhere of a stack of six or seven Yellow Warbler nests! Apparently neither cowbird nor warbler was quick to toss in the towel in that case. I hope that this nest successfully produced four warblers, which are now thinking of heading to tropical places if they're not already on the way.

Ha ..Clever bird! Great post. I had no idea that they would stack the nest like that.
Thanks again for an informative and witty post.

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…
