Bird food: It doesn't just come in bags

A wintry day along a Hocking County backroad, last Saturday, January 4th. Jeff White - standing by the car - and I were down in southeastern Ohio to cover my section of the Hocking Hills Christmas Bird Count. I've been birding this piece of turf for a number of years now, and it always produces interesting birding.

I have heard more reports of "missing" birds at feeders this winter than in any previous year, at least that I can recall. So much so that I've kept a folder of such complaints, in case some disease or other culprit comes to light. But in general, my answer is that birds are co-evolved with native food crops, and have been for FAR longer than they've had benefit of relatively new food sources provided by people and their feeders. If natural food crops are available, many birds will forsake your handouts in favor of nutritious native fare. At least, I believe that is usually the case. If it is a boom year for certain natural food crops, the species that feed on those may be especially apt to be AWOL at your feeders.

In general, it seems that the wintertime woodlands and meadows are bursting with food crops, at least in southeastern Ohio. I observed many examples of birds utilizing natural foods last Saturday, and managed to document a number of these relationships with my camera.

Jeff and I began our count with a bang, or more exactly, a loud sharp TSCHAK! At our very first stop, I jumped out of the car only to hear the noisy call of a Brown Thrasher, and quickly spotted the rufous-colored mimid in an adjacent thicket. The temperature was about 0 F when I made this image. I watched the thrasher for a bit, wanting to see what it might do. It quickly made its way into a tangle of climbing rose, Rosa setigera, one of five native Ohio roses in the genus Rosa, and began pucking and eating the rose hips. Rose fruit are high in vitamin C and other valuable nutrients, and given that the roses seem to have produced lots of hips, the thrasher is in a good spot.

We came across a small meadow richly carpeted with Indian grass, Sorghastrum nutans, and it was awash in sparrows. American Tree Sparrows (pictured) and Dark-eyed Juncos balanced like tiny acrobats, deftly plucking grains from the native grass.

We found four Hermit Thrush, and all of them were around sumac thickets. I've written about this hardy thrush and its proclivity for sumac many times, such as HERE.

While we watched the Hermit Thrush and a number of Eastern Bluebirds working the sumac, a Northern Flicker joined the crowd. The flicker is an extraordinary bird by any reckoning, and appears as if a committee of artists designed it without consulting one another. Their endpiece came out fine, however, and the flicker is truly a work of art. This is a male, as evidenced by the black malar strip, or "moustache".

The flicker quickly dug into the Staghorn Sumac, Rhus typhina, and thus joins a long list of avian species that I have observed feasting on sumac fruit.

In warmer seasons, Eastern Bluebirds are voracious consumers of insects. Come winter, they shift to a diet high in fruit - they are seasonally frugivorous, if you'll pardon my multi-syllabic descriptor. This stunning male - could there be a more striking shade of blue? - performs gymnastics to get at the cones of red cedar, Juniperus virginiana.

The cedar "berry" crops (they are really cones, as this tree is a conifer) seemed plentiful, and the bluebirds were taking full advantage.

We came up with 28 Yellow-rumped Warblers during the count, and all of them were around that most despised of native plants, poison ivy, Toxicodendron radicans. This female stands ready to plunder the waxy nutritious berries.

She dangles agilely to pluck a berry. Note how many fruit have gone missing, no doubt due to the depradations of Yellow-rumped Warblers or any of numerous other bird species that feast on poison ivy fruit.

A berry goes down the hatch. I wouldn't recommend that you try this, no matter how sharp your hunger pangs. Homo sapiens is quite vulnerable to the rash-inducing compound Urushiol; birds are unfazed by the itchy chemical.

Some day, I will write an essay in support of poison ivy, a plant with a great many virtues. It seems that only humans abhor this valuable plant, which is of vital importance to many species of animals.

A Northern Cardinal sits high in a tuliptree, Liriodendron tulipifera.This large forest tree is our only common and widespread magnolia. At one point, at least eight cardinals were in the crown of this tree, plundering seeds from the abundant, persistent fruiting receptacles.

This male cardinal has his face in the cuplike calyx, busily ripping out the hard woody seeds. To my eye, it seems that the tuliptrees have produced an especially bountiful crop of seeds, and obviously cardinals enjoy them. I wonder if this might be the reason that many people have lamented the absence of cardinals, especially, at their feeders. The bright redbirds are instead lured to the crowns of tuliptrees to snack on their seeds.

Good article. I have seen bird on the poison ivy berries.

A couple of days ago I was hiking and saw some blue jays in a beech tree trying to get at the nuts. The snow-covered forest floor was littered with a lot of the small spiky husks from the beech trees. I am guessing that most of them were from squirrels.

I have also seen a number of birds poking at sycamore seed balls. So, I am assuming that they eat these seeds, as well.

Amazing to see so many birds out feeding in their natural habitat. And it's heartening to know that even when they're not at our feeders, they are out there and they're getting enough to eat, as nature intended. I personally just installed a few squirrel proof bird feeders last month and it has made a big difference to my numbers this winter. Thanks for sharing these sightings!

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…
