Junco nest

The view from near the summit of Clingman's Dome in the Great Smoky Mountains National Park. This high altitude knob straddles the North Carolina/Tennessee state line, and rises to 6,643 feet - the highest point in the Smokies. Red spruce, Picea rubens, and Fraser Fir, Abies fraseri, form the dominant plant community but all is not well in coniferland. All of those dead snags are fir that have been attacked and killed by balsam woolly adelgid, Adelges piceae, an introduced insect pest.

Removal of the mature fir has wrought lots of changes in these mountain forests' ecology, including bird life. Nonetheless, many boreal breeders still thrive on Clingman's Dome, including Dark-eyed Junco. Juncos are one of America's best known birds, due to their frequency at winterime backyard feeding stations throughout much of the country. For instance, last winter in my state of Ohio, the Dark-eyed Junco was the second most frequently reported species tallied as part of the Cornell Lab of Ornithology's Project FeederWatch.

Yet only a tiny percentage of all of the people who buy seed and ogle juncos probably know the bird on its nesting grounds. These sparrows breed primarily in coniferous boreal forests, far to the north of the vast majority of folks who feed them in the winter. So, we'll go have a look at how little juncos are made.

At the end of the road leading to Clingman Dome's summit, there is a parking lot and then a steep half-mile trail to the absolute peak and an interesting observation tower. I made this trek both days that I was in the Smokies, hoping for clear skies and grand vistas for photography. It wasn't to be; both times clounds were thick and all-enveloping, allowing only the occasional misty portal into the mountains beyond.

The hikes were hardly a waste of time, though. Many interesting plants, birds and other animals will be seen as one lumbers up and stumbles down the mountainside. On Hike One I noticed an adult Dark-eyed Junco perched near the trail, bill stuffed with a large and scrumptious insect morsel. Obviously a nest was close at hand, complete with young, so I backed off and waited for Mrs. Junco to give up the lair.

And that she did, flitting down to a small well-vegetated opening and into a well-hidden alcove largely masked by plants. It's that small brownish opening dead center in the photo. She was in there for just a moment, and from my perch I could hear the young juncos' wheezy cries reach a fevered pitch as they sought her attention and the insect.

I have found a number of junco nests over the years, and they all pretty much have resembled this one in regards to site characteristics, although the composition of plant species varies. I will take a risk by breaking new etymological ground, and coin a new word for junco nests: phytotroglodytean (phyto = of plants; troglodyte = of caves; cave-dwelling).

Whatever you call a junco nest, it's almost certain to be well hidden. Scads of people walk within ten feet of this nest, every day, and I doubt that hardly any of them noticed it. Nor would I, had I not seen the adult junco with a mouthful of fresh food.

Right after the adult junco departed after a feeding, I found the right angle, and zoomed the camera into the junco's cave hoping that the youngsters would be visible. And one of them was; the others  - three, most likely - remained hidden in the nest cave's darker recesses. Their's is a neat little hiding spot, and juncos excel at creating such nurseries. They must know what they are doing - this species is one of the most common birds in North America.

The next morning, I was pleased to see Senora Junco once again busily delivering insects to the juniors and cramming them down their throats, as the nonstop parade of touristos huffed by up the hill, oblivious to the production of the little "snowbirds". Many of the passersby undoubtedly spend money to purchase seed that fuel wintering juncos, and only know these charismatic little birds from their frosty wintertime backyards.

Phytotroglodytean...it works for me.
And, although the view may not have turned out to be spectacular, it sounds as if the journey certainly was.
I wonder how many returned to their cars mumbling, "nothing to see."

Interesting blog. I didn't know Junco's nested in the Smokey Mountains. Thanks Jim.

Hi Nina,

Always lots to see in the mountains, as you know - just have to know where to look. I've got lots more cool stuff from the Smokies, if it doesn't get preempted by new stuff...

Glad you like the blog, Anon!

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…
