Masked Ducks at Alligator Pond

Alligator Pond, Laguna Atascosa National Wildlife Refuge in South Texas. This tiny wetland, at perhaps two acres, comprises a minute fraction of the sprawling 45,000 acre refuge. The pond proves the old adage, add water and they will come. It was teeming with birds, including Least Grebe, Fulvous Whistling-Duck, Common Moorhen, Blue-winged Teal, Tricolored Heron, American Coot, and more.

Of course, the pond’s namesake was lurking about. This big ‘gator was peering around, no doubt eyeing all of the potential snacks swimming about. If you are a water bird in such places, it pays to be on your toes at all times. More than one duck or grebe has undoubtedly swum right into the gaping maw of a giant alligator here.

The refuge staff was good enough to install a “gator gate”; a gap in the fence that allows the reptilian beasts to easily pass from the pond to the nearby lake. That beaten down path was created by roaming alligators.

Three clown-like Black-bellied Whistling-Ducks sit atop a nesting box, probably pondering how they might all fit in. This southern species is abundant in South Texas, but doesn’t normally range much further north. Formerly known as the “Black-bellied Tree Duck”, they nest in cavities and are often seen perching in trees.

We spotted our main target almost immediately – Masked Duck! These tropical relatives of the familiar Ruddy Duck are rare visitors to the southernmost U.S., occurring most frequently in South Texas. They have bred rarely, but most records are of non-breeders. I had sought this species in previous trips to this area, with no luck, so needless to say I was delighted to finally encounter this little stifftail.

Better yet, two Masked Ducks are present, and it didn’t take long for the other to show. These are females, with distinctive proportionately massive bills and striped heads. They aren’t much more than a foot in length and weigh less than a pound.

To me, these Lilliputian fowl were the crown jewels on a brief bird-filled two day foray in South Texas. But, I did see most of the other regional specialties, some of which are far gaudier than female Masked Ducks. I’ll share some of those other species 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…
