Confusing Fall Frugivore

Roger Tory Peterson coined the phrase "confusing fall warbler", because there is a suite of similar looking, dull-plumaged fall warblers that can be, well, confusing. In recent years some of the birding elite decry this expression, claiming that fall warblers are really not confusing. They fail to remember their beginnings, and that not everyone is an elite birder. Some fall warblers are indeed confusing, especially when seen in brief fits and spurts high in breeze-blown foliage.

The species that I am sharing below is a "sort of confusing fall warbler". It isn't as bad as some of its ilk, but certainly not as flashy and distinctive as a spring male would be.

Photographed last Saturday, right outside the Black Swamp Bird Observatory's building at the entrance to Magee Marsh in Ottawa County. Probably a first-year male, and he was a feisty little tiger. Note the prominent streaking below, pretty much from stem to stern.

He was actively engaged in frugivory, or fruit-eating. The berries of this Gray Dogwood held a strong allure, and the bird would make regular visits to sample them. It wouldn't swallow the fruit; rather it would carve out a hole in the top and suck the juices out. This species has a very fine bill and is well-known for foraging on nectar in migration and on the wintering grounds. During the breeding season in the boreal forests of northern North America, they depend heavily on spruce budworms.

Before long, this bird, if all goes well, will be in a place that many of us will envy once winter sets in. The tropical climes of the West Indies. A particularly tough individual spent part of the winter in Holmes County last year; you can see its photo in the newly arrived Ohio Cardinal.

I sure think some of the fall warblers can be confusing. Especially when you only see them coming and going.

I hate to see birds eating poison ivy berries. It makes my throat constrict. I am always amazed that they aren't affected by the poison.

Hi Jim! I've always found that phrase a self-fulfilling prophecy: call 'em challenging, call 'em subtle, call 'em late for supper--but to call these birds "confusing" has made generations of beginning birders simply give up on them. I was happy to see the new-new-new Peterson abandon those words.
Hope you're very well! Coming to AZ sometime soon?

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…
