Rare Beach Stuff

I went up to the International Headquarters of Black Swamp Bird Observatory today, to join in with the 1st possibly annual Artists and Authors Event. A great time, met some nice people and saw many more that I know but don't often see. Thanks to all who assembled this event and made things flow so well.


There was a bit of time on either end of the event to poke around the vast marshes of Magee Marsh Wildlife Area. Many know this place is a beacon for birds, and it is. But there's much more. The big marsh on the east side of the causeway road as you head out towards the legendary bird trail is the second best marsh in the entire western Lake Erie basin - at least in Ohio - in my opinion. There are a number of very rare plants growing here, and other more common native plants that have been in a downward spiral in other marshes.


Then, there is the beach. Not the one associated with the state park to the west; the one at the end of the causeway road where it jags sharply to the left. This beach is undisturbed and always has interesting flora and fauna.
A view of the "good" beach. Interesting plants occur here, some quite rare. That zone of low grass is an example.
It's Purple Sand Grass, Triplasis purpurea, which is threatened in Ohio and only known from Lake Erie beaches.
This one's even cooler, and an equally rare denizen of Lake Erie beaches. Prostrate, it's adapted for life on the outermost limits of a beach, where waves regularly pulverize it. Seaside Spurge, Euphorbia polygonifolia, is an Atlantic Coastal Plain disjunct. About ten tousand years ago, it migrated eastward into the Great Lakes via interconnected bands of lakes and wetlands that were present following the retreat of the Wisconsin glacier, and was eventually stranded inland.
Blue Dashers galore in the Staghorn Sumac thickets on the back side of the beach. This male was one of probably hundreds - thousands if one looked far and wide enough. This beach seems to attract droves of dragons, and is a great place to watch for rarities, like the state record Striped Saddlebags that Rick Nirschl found here last year.
I found this plant growing in dry sandy soil around the entrance to the bird trail. It's not one I've seen in Ohio and threw me at first. I thought it might be a Potentilla, but when I got back and had a look at the digital images the lightbulb clicked and I remembered seeing it elsewhere - Puncture Vine, Tribulus terrestris. It's in the Caltrop Family, Zygophyllaceae, and is native to Eurasia. The only member of this family found in Ohio, it is known from only a handful of counties, but is considered a troublesome weed elsewhere. You may recognize the genus name, Tribulus. It is commonly sold in health food stores as an hebal medicine, touted for improving sexual function among other things.

The day ended with a bang. A bunch of us were standing around, getting ready to leave, when in came a call from Larry Rosche, who along with Judy Semroc had just discovered a Piping Plover on the beach in nearby Port Clinton. This was pretty much on the way home and I'll always make an effort to look at a Federally Threatened species, so off to the Port it was.No disappointments on arrival, either. Larry and Judy were still there and had the bird in sight. It's a juvenile, just born this summer, and had a band on its leg. Dave Lewis, Judy and Jen Brumfield all got great shots - this one is mine - and we might be able to see the legs better in one of theirs. If so, we'll send a pic off to the Federales and see if we can't find out where and when it hatched. A beautiful little beast; very pale and showing the scaly feather edgings of a juvenile, it also was very vocal. Piping Plovers emit a pleasant, mellow two-toned whistle.

Managed this pic of the bird in flight. It's at right, showing a bold white wing stripe sandwiched by extensive blackish areas. That's an adult Sanderling, in obvious molt, leading the way.

We appreciate Larry using a telephone - just like the olden pre-Internet days - to tip everyone off so we could get there in time to see this rarity.

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…
