The Gloom of Night

I write this blog from Owings Mills, Maryland, a beautiful tree filled suburb of Baltimore. I am indeed fortunate to have been put in contact with Donna and Henry, my hosts, who are putting me up in their gorgeous house overshadowed with towering Tulip Trees. I'll be speaking at the nearby Irvine Nature Center's annual Native Plant Conference tomorrow morning. They've been doing this event for some twenty years, and always attract a good crowd. I'm looking forward to that, and being on the same slate with Doug Tallamy and William Cullina. Hard acts to follow.

Since the incomparable Cape May, New Jersey is only about three hours off to the east, I'm planning on going there Sunday. If it works out, I'll have some cool stuff to share, I'm sure.

Anyway, I just got some really cool stuff for my camera. They are mega-macro lenses, and are awesome! It's like shooting photos through a microscope. A bit of a learning curve to figuring out light settings, apertures, and that sort of thing, but I had my first self-taught lesson last night. A few photos follow...This tiny little beast is one of the treehoppers, and several dozen of them could pack onto a quarter. During the day, they often wedge into the axle of a leaf, blending remarkably well with the plant. At night, they become more free-ranging, although when spooked by giants with flashing lights, still tend to retreat to the junction of a leaf and stem, where they at first blush look remarkably like a stipule.

This tiny cricket is a Say's Trig, I believe. It is a quarter-inch or so in length. You've heard trigs. They produce low trills that are an oft-present background noise. This species makes a musical, silvery trill that carries well, considering the miniscule size of the musician.
As you can imagine - or may not be able to imagine - I was quite pleased to find this big katydid. It produces an interesting and very distinctive song that sounds a bit like a raspy frog - ree-dip! It's an Oblong-winged Katydid, and like the rest of their ilk, can be very hard to find. Nearly impossible during the day, when they sit around in the foliage looking just like leaves. I heard this one, and finally located him sitting low on the leaf of a Giant Ragweed. Like nearly all katydids, they are nocturnal and sing at night. Keen of senses, they'll clam up when a person draws near, increasing the challenge of finding the songster.

A closer view of its upper body. We know it's a male, one, because it was singing, and two, because of that traingular brownish patch. That is the stridulatory area; the parts that he scrapes together to produce his song. These raspy melodies are known as stridulations. Katydids are beautiful and fascinating insects, but certainly underappreciated. Few people ever see them!

A closer view of the base of the Oblong-winged Katydid's wings. These insects are essentially doing what male birds do - singing to attract mates. The singing insects start to come on strong just about the time that our breeding birds are waning, having already fledged their young. For birders, learning the insect vocalizations can be terrific practice for keeping one's ears in tune. From mid-July til frost, you'll have a bounty of challenging new subjects to learn.

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…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
