"Golden Eagle" attacks baby! Not

I can't even bring myself to write about this latest YouTube silliness that duped about eight million people into believing that a "Golden Eagle" roared out of the sky and snatched up a toddler. How it is that people believe such stuff is beyond me; maybe I am too cynical... Anyway, if you somehow, SOMEHOW, managed to miss this latest globally viral video hoax, CLICK HERE.

The hoaxers 'fess up HERE, allowing babies worldwide to breathe a bit easier...

Crow roost

I found myself in this spot, in rural Jackson County, Ohio, last Saturday at twilight. I was down there to cover my turf for the Beaver Valley Christmas Bird Count, so-named for the sprawling metropolis of Beaver several miles to the south. That forested ridge across the field is one of many in the area. The topography of this immediate region still shows the effects of a massive river system long obliterated by past glaciation. The mighty Teays River, which arose near the present day Great Smoky Mountains National Park, coursed northward and into Ohio. Its main channel and side tributaries left behind broad flat valleys, such as above, interspersed with sharp ridges.

If you are an American Crow, these razorback ridges make great roosting spots. The birds can see everything for some distance in every direction, and potential enemies have no chance of sneaking up undetected. Click the photo to expand it. All of those specks are crows, and this is but one tiny part of the local roost. Such an aggregation of crows is known by the sinister term "a murder of crows".

Crows have roosted in this immediate vicinity for a long time, probably as long as I've been doing this count and that's been 15 years or so. It's a spectacle, watching all of the birds return from far and wide at sunset. The air is filled with a cacophony of caws as the birds greet each other and otherwise interact, constantly jabbering as crows will do. Occasionally a collective nervous tremor ripples through the flock, and they briefly rise into the sky as of one mind, their chatter rising to a fevered pitch and totally dominating the surrounding landscape.

 

This video offers a mild taste of the ambience of the roost. I did not reach the roost site until a great many of the birds were already in residence, and didn't have time to thoroughly explore the area to tally the roosting zone in its entirety before nightfall. I turned in an estimate of 7,000 birds, but there are far more than that in the area. Next year I intend to get to this spot sooner, and attempt to make a more accurate accounting of these crows.

Christmas Bird Count season

Jackson Lake, Jackson County, Ohio. A brief respite from gray skies and drizzle allowed me a scenic shot. Minutes earlier, a rainbow arced across the sky, but I was not in a good position to capture that scene.

I was down in the Hill Country last Saturday to participate in the Beaver Valley Christmas Bird Count, just as I have for many years now. Yesterday, in stark contrast to the beauty of this scene, Bernie Master and I covered our turf for the Columbus CBC. Our terrain there is mostly highly urbanized or industrial, yet we managed a number of interesting finds.

As usual, my camera was in tow and I recorded some things of interest. More to follow...

A brief essay on the House Centipede



House centipedes creepy but cool
 
Sunday December 16, 2012

NATURE
Jim McCormac
 
You and your family aren’t the only animals in your house. Many other critters lurk in the hidden nooks and crannies of your dwelling. These creepy-crawlies are often out of sight and out of mind, but every now and then, one bursts forth in spectacular fashion to remind us we share quarters with some undesirable “camp followers.”
 
As humans have marched about the globe, we’ve unwittingly carted along all manner of hangers-on — creatures that are so adapted to Homo sapiens that they rarely, if ever, live out of our fold.

Depending on your inclinations, one of the coolest or creepiest of these unwanted domestics is the house centipede ( Scutigera coleoptrata). If one of these many-legged arthropods scuttles out of the woodwork, it is sure to be noticed. Its creep factor is enormous. House centipedes don’t walk or run as much as they glide, sort of like a spooky undulating feather magically levitating across the wall. They aren’t tiny, either — a magnificent specimen can stretch the tape to 2 inches. That is big enough to elicit shrieks of terror.

Fortunately, house centipedes usually do their wandering under cover of darkness, and thus seldom clue in homeowners to their presence. If you’re really curious, drop down to the basement with a flashlight and start probing the dark recesses of crawl spaces and junky corners. You’ve got a good chance of unearthing a house centipede.

Centipedes are predators and adept at running down and slaying prey. When on the hunt, the centipede constantly tests the road ahead with its sensitive antennae. When a victim is sensed, the many-legged monster pounces and injects potent venom via a set of modified legs. If there is an upside to this horror show, it is the fact that the centipede is generally offing other undesirables such as ants, bedbugs, spiders, silverfish and cockroaches. If we continue with an optimistic outlook, we can also be glad that house centipedes aren’t 4 feet long and eyeing us hungrily.

House centipedes originally hailed from the Mediterranean region but hopped into people’s baggage long ago. They’re good travelers and now occur throughout much of the world, although almost always close to people. While these centipedes can flourish outdoors, they aren’t particularly cold-tolerant, and autumn’s chill drives them back indoors with us.

That soft tickle across your cheek that snaps you from sleepy reverie in the wee hours? You don’t want to know.

MBS and BWD


I received my brand spanking new edition of Bird Watcher's Digest today, cracked it open, and was pleased to see this full-page ad for the upcoming Midwest Birding Symposium (MBS). Not only that, the ad features Dave "Birds From Behind" Lewis and his infinitely better half, Laurie Boylan, both of whom are stalwart Ohio birders.

If you've been to MBS, I don't have to sell you on this birding extravaganza, and I trust that you'll be back in 2013, September 19-22 to be exact. If you've not been, well, please do put MBS on your calendar. It may not be the biggest avian fest, but it's the best! And with some 1,000 birders converging on the idyllic Lake Erie village of Lakeside, Ohio, MBS is certainly no small potatoes! There's outstanding speakers galore, an amazing vendor's hall, excellent local birding at the peak of fall migration, and so much more. CLICK HERE for a pictorial recap of the 2011 affair.

It's never too early to plan one's calendar, so click on over to the Midwest Birding Symposium website and PREREGISTER NOW!

A quick plug for the mag that sports this MBS ad. Bird Watcher's Digest is, simply put and in my totally biased opinion, the best general interest birding publication on the market. It launched in 1978 - I purchased and still have the inaugural issue - and is still ticking strong. If you haven't read BWD, try it, you'll like it if you like birds. A subscription also makes for a fine Christmas present! GO HERE to learn more about BWD.

Inquisitive otter investigates camera

Back at the tail end of October, I shared a wonderful video of a family unit of River Otters, Lontra canadensis. The videographers were David and Laura Hughes, who have taken trail cam cinematography to a fine art and are achieving amazing results. The previous otter video can be seen HERE.

Well, Dave and Laura have done it again, with the following crisp vid of momma otter rooting around with two of her offspring. The sharp-eyed elder otter spots the camera, and takes a gander at it. This film was shot at the Hughes' now legendary Monroe County, Ohio game trail.


Thanks, as always, to Dave and Laura for sharing their work with us. Their videos offer glimpses into the lives of mammals that are normally very hard to observe, at least for very long, in the field.

Owl Symposium! February 15-17, 2013

Mark your calendars in ink for the weekend of February 15th thru the 17th. The Ohio Ornithological Society is putting on a conference that's all about those wisest of birds, the owls. The venue? The fabulous Mohican State Park lodge, nestled in the thick of a 5,000-acre forest full of wonderful birds. GO HERE for details about the Owls of North America Symposium.
 
A sleepy Barred Owl, Strix varia, fails to acknowledge your narrator. I photographed the animal as it slumbered in a gnarly Swamp White Oak along a back road in the Killbuck Marsh Wildlife Area. Barred Owls are one of only two owls that occur in Ohio that have dark eyes. I'm sure you can guess the other. We'll be out looking for owls in their natural haunts at the symposium, and there's usually an obliging pair of Barred Owls a mere stone's throw from the lodge.

This Burrowing Owl, Athene cunicularia, did acknowledge your blogger, although I wasn't nearly as close to the animal as the photo suggests. The bird pierced me with its fierce yellow eyes as it perched at the entrance to its burrow in Cape Coral, Florida. Believe it or not, there are four Ohio records of these lanky-legged ground dwellers, and we'll probably have others. Burrowing Owls have a broad but patchy distribution throughout the Americas, and western U.S. and Canadian populations are highly migratory.

Our keynote speaker hails from the west, just like this owl. Denver Holt is director and founder of the Owl Research Institute and one of the world's foremost experts on owls. He is a dynamic speaker, and a hoot to listen to. The chance to hear Denver is worth the price of admission alone. His subject is awesome - Snowy Owls, Bubo scandiacus, and his work with them on their home turf, the high Arctic of Alaska.

Its "ears" flopped down like a hound dog, a plump-looking Long-eared Owl, Asio otus, looks down in wonderment. I luckily espied the bird from afar, long before it saw me, and managed to furtively sneak near enough for some photos before it detected my presence. This, apparently, is what a Long-eared Owl in repose looks like - fat, fluffy, and ears adroop. Seconds later, it snapped to attention, sleeking its body to impossibly slender branchlike propertions and erecting the ear tufts to complete the illusion of a broken off snag.

Gail Laux of the Ohio Bird Sanctuary will be on hand and giving a lecture about the various Ohio owls and their amazing anatomy and habits. She'll have props, too - live owls that the Sanctuary has taken in, but which can't be released due to injuries. In addition to up close and personal owl encounters, we'll also be out-of-doors and finding wild owls, in addition to all manner of other birds, As you probably know, this has been a bonanza year for crossbills, and the hemlock-choked Mohican Gorge usually has them.

Photos of Northern Saw-whet Owls, Aegolius acadicus, often elicit involuntary "aahs" from people, and I've got to admit - they're cute. You wouldn't be oohing and aahing if you were a White-footed Mouse and saw this thing swooping in, I'll tell you that much. To the rodents, this is a feathered Freddie Krueger come to life. This one was photographed during a banding operation.

Bob Placier and Tom Bartlett, who have banded hundreds of saw-whets between them, will give a program about their fascinating work with eastern North America's smallest owl. As a major perk, they'll set up nets and try to capture saw-whets on Saturday night.

There's much more, including live music by the inestimable band of birders, the Rain Crows, on Friday night. These symposia are a lot of fun, and a great chance to learn, see lots of birds, and meet lots of like-minded people. Even if you live in far-flung places such as Uzbekistan or West Virginia, I'd encourage you to make this scene.

Registration and all of the other details are RIGHT HERE. Hope to see you there!
