Brewer's Blackbird

This stunning image of a rather rare blackbird, for us Ohioans, comes courtesy of Aaron Boone, who snapped this photo on November 1 in Champaign County. When seen like this, the iridiscent silky tones of the plumage are apparent and one can see why Brewer's Blackbird has sometimes been dubbed the "Satin Bird" or "Glossy Blackbird". Thanks to Aaron for sharing this photo with us.


The range of Brewer's Blackbird, map courtesy Birds of North America online. Look how close it comes to Ohio as a breeder in Michigan. There as yet is no Ohio breeding record, but I think that this species could well be found nesting here. Extreme northwest Ohio is the place to look, and Williams County would probably be the numero uno hotspot. I think next year it is time to organize a "block-busting" weekend in Williams County and finally pin this species down. We'd find lots of other interesting species as well.

Below is a piece I wrote about possible new additions to the Ohio breeding bird roster, published in the inaugural edition of the Ohio Breeding Bird Atlas II newsletter. I hope that the prediction comes true!

Brewer’s Blackbird. It is almost surprising that this species has not been documented nesting in Ohio yet. Brewer’s Blackbird would be easy to overlook, as possible nestings would be in a region that isn’t heavily birded, and it would certainly be possible to dismiss them as other more common blackbirds like Common Grackle without a careful look. They would also likely occur in towns, parks, farms or other well-settled and relatively uninteresting areas that could easily be ignored by birders.
Brewer’s Blackbirds began an eastward expansion around the 1920’s, and have colonized as far east as southern Michigan and eastern Ontario, Canada. This species has an interesting relationship with Common Grackles where the two come into contact. There is competition between the two species, and in some areas grackles dominate and apparently exclude Brewer’s Blackbirds in suburban sites. In less populous open field and brushland habitats, Brewer’s have dominated. Brewer’s has bred within fifty miles of Ohio in Michigan, and Fulton and Williams counties would be key areas in which to search. Look for them at places like Lake La Su An Wildlife Area in Williams County, the Maumee State Forest in Fulton, Henry, and Lucas counties, and in or around small towns in this region.

Jim,
Is Brewer's in Magee Marsh in spring? I believe we have seen it during birding at Warbler weekends?

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…
