Adam Grimm: Ohio Wetlands Habitat Stamp winner!

Ohioan Adam Grimm, artist and conservationist, has won the Ohio Wetland Habitat Stamp competition with his rendering of a Northern Pintail. Each year, about two dozen artists from far and wide vie for the honor of having their artwork featured on this stamp, which was introduced in 1982. Competition for top honors is fierce, and the winning entry is selected by a team of bird-savvy judges.

Adam, who hails from Elyria, Ohio but now makes his home in North Dakota, burst to prominence in 1999, when his beautiful painting of a Mottled Duck won the Federal Duck Stamp competition. That honor put him squarely in the rarified atmosphere of a relative handful of wildlife artists who have had their work grace the Migratory Bird Hunting and Conservation Stamp, which had its inception in 1934 and has since raised over $750 million for habitat acquisition. Chances are great that if you are a birder, you've ogled interesting birds on property purchased with Duck Stamp dollars.

Not one to forget the conservation roots of the Duck Stamp, Adam plowed some of his winnings into his home state's lone federal refuge, the Ottawa National Wildlife Refuge along Lake Erie. If you've birded that area much, you've probably seen this sign marking a beautiful tall grass prairie. It was Adam's generosity that made its restoration possible, and now we can enjoy Bobolinks, Sedge Wrens, and Upland Sandpipers in and around this prairie. Coincidentally, over 90% of the funds to purchase Ottawa National Wildlife Refuge came from Duck Stamp dollars. You can buy a Duck Stamp HERE.

Back in 2007 or thereabouts, the fledgling Ohio Ornithological Society asked Adam if he would be guest of honor at a special OOS fundraiser, to help raise money to assist in the purchase of land. Grimm graciously and enthusiastically agreed, and thanks to him we were able to pull in a sizeable chunk of change. That money ultimately went to provide a necessary match for Clean Ohio funds, and along with The Nature Conservancy we were able to help purchase a key parcel of land in TNC's Edge of Appalachia preserve in Adams County.

Finally, here it is - Adam's winning Northern Pintail. It'll adorn the 2014 Ohio Wetlands Habitat Stamp.

This isn't Adam's first time at this dance. He won the Ohio stamp competition in 2005 with a beautiful portrayal of a Wood Duck, and he has also won state stamp competitions in Alaska (twice), New York, and Washington.

Congratulations to Adam Grimm, who is not only a great artist, but also a true conservationist.

Bank Swallows grace U.S. Postal Service envelopes

The U.S. Postal Service released new stamped envelopes today that feature artwork depicting the Bank Swallow, Riparia riparia, known elsewhere in the world as the Sand Martin. Matthew Frey of Annapolis, Maryland is the artist. Bank Swallows have a huge distribution and occur on six of the seven continents. I heartily applaud the U.S.P.S.'s interesting choice of our smallest swallow to grace their newest rendition of the 58-cent Forever Envelopes. Read more about the stamp HERE.

Long-eared Owls in willow thicket!

Yesterday, along with a few other folks, I found myself skirting along a large wetland complex in the western marshes of Lake Erie. It was a gloomy, overcast day, with wet snow/rain spitting constantly in hypothermia-inducing temperatures. Nonetheless, spring was in the air, if one were to believe the birds. Flocks of blackbirds were here and there, and the boldest of the early returning male Red-winged Blackbirds were teed up and proclaiming their territories with guttural conk-ah-REE-onks! Waterfowl were on the move, and scores of Tundra Swans were moving about, restless to push on north to their Arctic breeding grounds.

In spite of all the conspicuous avian action, our attention was riveted to the innocuous looking willow thicket above, at least for a memorable while.

This shrubby copse is just like acres and acres of the same stuff in Lake Erie wetlands, but this patch held a special treat. In fact, I suspect that many such thickets hold the feathered treats that we'll behold in just a second - it's just that few people look for things in such places.

Look closely - we're being watched! A Long-eared Owl, Asio otus, peers out at your narrator and his companions. This owl and its compadres were devilishly hard to spot in the dense willows. As we scanned the patch and ogled an owl, more would come to light. At one point, I was drawing a bead on this bird with my camera, and noticed another owl, barely visible, in the backdrop. We tallied four but I bet more were present. Our reluctance to disturb them precluded more aggressive surveying.

By sidling along the roadway, some fifty feet away, we were able to discover open portals into the thicket and clearer views of some of the owls. This is where my 500 mm lens really comes in handy. It isn't necessary to impinge on the birds' comfort zone in order to make decent photos. I also had my scope along, and was able to set that up a fair distance away and still provide everyone with killer looks, same as in this photo. The owls noticed us, obviously - what do they NOT notice? - but never showed signs of being on high alert.

Take a close look at this owl. A very cool and almost surreal element of owl physiology is on display.

The owl in the previous photo, and the chap above were both facing away from the road. But wait - they're still looking directly at the camera! Owls have fourteen neck vertebra, double our seven, and that allows them to twist their neck nearly 180 degrees and look directly behind them.

Long-eared Owls are not a rare bird, and are common throughout much of the northern boreal forest. They stage poorly understood southward movements in winter, and are regular visitors to Ohio and other states south of their primary breeding range. There are undoubtedly FAR more Long-eared Owls around than is supected, and when one sees these masters of camouflage imbedded in a dense willow thicket such as this, it becomes apparent just how easily they can be missed.

I think many Ohio birders have a skewed perception of Long-eareds' winter habitat, because so many people are used to seeing them in the pine groves at Killdeer Plains Wildlife Area and other select conifer groves. But it should be remembered that, with the exception of the Red Cedar, Juniperus virginiana, and Virginia Pine, Pinus virginiana, conifers are rather local and limited in distribution in Ohio. And even the two aforementioned species are not common statewide, and the other five native species suitable for owl roosting are very limited in distribution. In several areas where Long-eared Owls regularly turn up roosting in conifers, such as Killdeer Plains, there are NO native conifers or at best a smattering of Red Cedar. The birds are roosting in artificial plantings.

On several occasions, I've seen Long-eared Owls roosting amongst the dense gnarled branches of Pin Oak trees, Quercus palustris, and I suspect that's where the Killdeer Plains pine grove birds retreat when the human presence becomes too much. Pin Oaks are often very common in and around good Long-eared sites. They also favor dense grapevine tangles, which are found nearly everywhere, and good luck spotting owls in such haunts.

A key to devining possible locations for Long-eared Owls involves suitable hunting habitat. They hunt over open and semi-open ground, and if an area has Short-eared Owls and Northern Harriers, there is a good chance that Long-eareds are also in the immediate vicinity. The latter are strictly nocturnal, though, and thus much harder to discover. It involves lots of peeking and peering into dense vegetation, and/or much luck.

I want to thank Jeff Finn for pointing these birds out to us, and taking us to the spot. It's an interesting story as to how they were discovered, which was quite serendipitous. The location cannot be divulged, though, as the owls are on lands that are not publicly accessible, and I am always loathe to reveal Long-eared Owl roost sites as human pressure can become heavy once they're known. But now that we've seen these deciduous willow-roosting birds, we have a good search image for a "new" habitat in which to seek owls.

Mammalian Dispersal - those annoying prickly burs

 
While traipsing through Kiwanis Park last Sunday, where I made the Skunk-cabbage images of the previous post, I encountered the remnants of this plant. It is Virginia Stickseed, Hackelia virginiana, and it is a much cursed plant indeed. When young or in bloom amongst the crush of other summertime greenery, Virginia Stickseed does not stand out and is likely to be overlooked. With age and the ripening of fruit, even non-botanist explorers notice - and curse - this rather weedy borage family member.

The fruit of the stickseed, shown above, are a marvelous adaptation for mammalian dispersal. The exterior of the fruit is heavily armored with stiff hook-tipped bristles - ideal for adhering to passersby. Many a hiker has had the misfortune of inadvertently bumbling through a patch of this plant, only to look down and see that his/her legs are covered with burs.

While humans now play a role in moving stickseed and other plants around, our adhesive-fruited flora co-evolved with animals such as this White-tailed Deer. The aforementioned Virginia Stickseed can be a robust plant, and typical luxuriant specimens place their fruit at an altitude perfect for catching furry deer bodies. It probably does not behoove wild mammals to become coated in sticky burs, and their fur has become quite sleek and good at repelling would-be hitchhikers, but some of the plant fruit will stick at least long enough to ride to a new locale.

Just as surely as tanagers and warblers migrate, so do plants. Plants have all sorts of migratory ploys in their bag of tricks, including wind and water dispersal, transport by all manner of insects, forceful physical ejection of seeds, and more. People probably tend to notice the mammalian dispersal plant tactics the most, because these plants don't discriminate against the various mammal species so we get involved in the process too.

A real Jeckyll and Hyde plant, the Showy Tick-trefoil, Desmodium paniculatum. This pea family member is decidedly an ooh and ahh plant when in flower. When it goes to seed, the same fawning admirers often end up cursing the tick-trefoil. Desmodiums produce flat, often triangular fruit known as loments, and loments adhere wonderfully to pants legs and other clothing. I'm sure you've picked some up in your travels.

Columbus Dispatch photographer Eric Albrecht is one of the best in the business, and goes to any length to get his shots as on this trip into Shawnee State Forest. Beating the brush like this often means legs covered with Desmodium loments. If Eric were to fail to rid himself of all the sticky loments, he is liable to transport them far distances and thus aid in the plant's dispersal.

Bur-bearing plants are found in many families, and exhibit great variation in stature. There are even elfin mammalian dispersal plants that hold their fruit at the low level of a chipmunk. While the odd bur undoubtedly gets taken for a ride by hyperactive chipmunks, their primary method of plant transportation is caching, and forgetting, seeds.

 White-footed mice and other rodents likely transport their share of seeds, too, without intending to.


Mice and other rodents often dwell in rocky cliffs and outcrops, and such sites are home to this lovely little plant, the Dwarf Enchanter's Nightshade, Circaea alpina. Its tiny ellipsoid fruit are beset with sticky hairs, and are in perfect position to latch onto small rodents making the rounds of the rocks at night. Thus, newer and higher ledges can be occupied by the plant, thanks to the mice.

Long-fruited Snakeroot, Sanicula trifoliata, is one of four very common Sanicula species in Ohio. This one shares limelight with several other dozen species of plants that were discovered and described to science in Ohio. The plant probably cares less about that distinction than it does about sticking its burs to some passing mammal.

An Eastern Cottontail, a likely common transporter of Sanicula snakeroots. These plants often grow luxuriantly in prime rabbit habitat, and are of the perfect height to snare passing bunnies.

Next summer and fall, when you pause to pluck burs from your clothes and cast them to the ground, just take note that you've been outfoxed by the plant world.

The skunks burst forth - it is offically spring!

A springy quagmire a mere seven minutes from my house, and a place to which I make an annual pilgrimage each year to confirm spring's arrival. I know that I write about this every year, but I cannot help myself. This has been a long wintry winter, and I and many other northern tundra-boys and girls eagerly seek out definitive signs of spring.

Speaking of the title of this post, and skunks, the mammalian form is also in full spring fever. You'll be smelling their pungent musk frequently, and seeing the aftermath of skunks who were unsuccessful in crossing the road. But this story is about Skunk-cabbage.

The aforementioned boggy spring is Kiwanis Park, and I was there this morning to document the full-fledged emergence of the Skunk-cabbage, Symplocarpus foetidus. I was at this spot for other purposes back on January 16, and was shocked to see that at least one of the Skunk-cabbage plants was already in full bloom. That one jumped the gun by a longshot; today, hundreds of plants were up and the colony was at or near its peak of bloom.

If you are a plant bold enough to thrust from the mire in February, it helps to be thermogenic. Skunk-cabbage produce their own heat as a by-product of growth, and the immediate environs of an actively growing skunk is plenty warm enough to melt away the snow and ice.

A luxuriant passel of Skunk-cabbage. Each of those curious fleshy conical spathes harbors the flowers. The purple and green hoods provide a toasty warm tent that shields the pollen-producing parts from the often much chillier conditions outside. It might be several dozen degrees warmer inside the spathe! While Skunk-cabbage's choice of habitat often limits who might see them - casual hikers tend to avoid boot-sucking quagmires in late winter - I'm sure the unititated occasionally stumble into them. I wonder what someone who has no idea of their existence thinks when they clap eyes on a flowering skunker. Probably think it's a weird fungus of some sort, rather than a close relative of one of our most beloved spring wildflowers, the Jack-in-the-pulpit, Arisaema triphyllum.

Proof of flowering is in the pollen, as botanist Daniel Boone would say. To see the true flowers of Skunk-cabbage, one must peek through the flap in the spathe. If you do, this is what you will see. The oblong-shaped club is the spadix, which is littered with the tiny greenish flowers. Look closely and you'll see pollen grains on the flowers and the surface of the spadix.

The blooming and leafout of Skunk-cabbage is largely asynchronous: the leaves do not emerge and reach full luxuriance until after the flowers are done and withered. Only a few leaves were in the early stages of unfurling today. Come back later in spring and it'll resemble a well fertilized cabbage garden in this spot.

The botanical skunks long get the jump on more traditional wildflowers. This raggedly looking rosette of Swamp Buttercup, Ranunculus hispidus, leaves was growing with the Skunk-cabbage, but it'll be two months or so before their glossy lemon-yellow flowers show themselves. The birds know that spring is here, though. Well making my photos, I was serenaded by Northern Cardinals, Carolina Wrens, Northern Flickers, Song Sparrows, Mourning Doves, and others.

While it may only be late February, now that the Skunk-cabbage are at the pinnacle of bloom, there is no denying the impending Spring.

New River Birding & Nature Festival, here we come!

The famous New River bridge at Fayetteville, West Virginia, as seen from Long Point. The deck of that bridge is about 877 feet above the roiling waters of the ancient New River, which is actually one of the world's oldest streams. The scenery in this part of the world is nearly unrivaled, anywhere, and the biodiversity is nothing short of astonishing.

Enter the New River Birding & Nature Festival - the best way for birders and others interested in nature to immerse themselves in the flora and fauna of southern West Virginia. This year, the festival ranges from April 29 - May 4 and YOU should be there!

This pleased group is in the midst of watching a male Golden-winged Warbler make its rounds, singing all the while. Topnotch and often hard to find birds such as the Golden-winged are a festival staple. Helping everyone to find the specialties is an all-star cast of guides, many of whom pull double duty as evening speakers. GO HERE for a roster of the guides.

The word "Nature" is in the event's name for a reason. The mountains of West Virginia teem with all sorts of nonbird animals, everything from Box Turtles to Worm Snakes to Red Efts to Black Bears. We pause to look at them all.

A real field of dreams, the fabled Bobolink field, high on a grassy knoll well up on a remote mountain. Although most of us have probably seen Robert O' Lincoln, it's incomparable to clap eyes on the black, golden, and white males skylarking all over this magical meadow, gurgling their bouyant R-2 D-2 melodies to the assuming females.

Certainly not my best effort in the realm of bird photography, but this shot tells a story. It is a bird that not many people get to lay eyes on - a female Cerulean Warbler. You'll generally see far more of the sky-blue males. The mountain where I made this image is full of Ceruleans - probably the greatest density that I've seen anywhere. What was particularly cool about this particular bird is that she was actively harvesting the exfoliating bark from those grapevines for her nest. That's another cool dimension of the New River Birding & Nature Festival - we know tons of hotspots where rare experiences such as this are possible, if not probable. Seeing a glimpse of a Cerulean Warbler high in a treetop is Birding; observing a female gathering nest material at close range is Bird Watching!

I am tasked with leading groups to Cranberry Glades, way up in the Monongahela National Forest, and what an onerous job that is - NOT! Even though the boardwalk that winds through the gnarled Red Spruce is only 1/2 mile in length, it can take a few hours to traverse its path. The birds are insane - it's like being teleported to Canada. Winter Wrens, Canada Warblers, Red-breasted Nuthatches, Northern Waterthrushes and many other boreal species breed here. There is a local nesting population of Red Crossbill, and they often frequent the nearby visitor's center. The plant life is incredible and includes numerous interesting and rare species.

Almost stunning beyond words, a bouquet of brilliant orange Flame Azalea flowers enlivens an early spring West Virginia woodland. The botanical diversity is extreme, and I've found that even people who have not paid plants much mind find themselves getting caught up in the charms of vegetable matter such as this azalea. Bring a camera - photo ops abound.

Another happy group, this time because a cooperative male Mourning Warbler sang its heart out for them as it worked the margins of its turf.

We see a lot of repeat customers at the New River Birding & Nature Festival, and small wonder. I think this'll be my seventh consecutive year leading trips, and it is without doubt a highlight of the season for me. I think you'll like this part of West Virginia, too.

Barn Owl!

Pastoral Knox County, Ohio. This is Barn Owl country, and some of the barns such as the one in this photo are haunted - haunted by monkey-faced owls. Whether or not this particular barn has an owl in residence I do not know, but it isn't far from a barn that does.

Barns Owls are certainly not common in Ohio, and are officially listed as threatened. I suspect there are many more than we know about, though. They are strictly nocturnal, and only likely to be found when roosting during the daytime, and the roost is likely to be in someone's private farm outbuilding, and such places are not frequented by birders.

Thus, I was delighted to get a recent email, telling me of an owl in residence in the aforementioned Knox County. The homeowners are nice as can be, and were willing to allow me to visit and have look at their owl.

So, on a recent Saturday, I piled Peter King and Bruce Miller in the car and headed up to meet the Barn Owl's landlords, and hopefully the owl as well. Upon entering the barn, it didn't take but a New York second to figure out where the bird's favorite haunt was - the floor underneath was dappled with enormous owl pellets and painted with a fair bit of whitewash.

We glanced up into the rafters, and there she was, tucked in and paying us absolutely no mind. And it is a "she": note the lovely tawny wash to the breast and the copious sprinkling of black dots. Males tend to be much whiter and considerably less speckled. This bird does appear to have an injury of some sort on its breast, but apparently it is healthy enough and eating like a horse. It's been using the barn for over a month, and the piles of pellets attest to its vole-catching prowess.

This is a working farm and a working barn, and apparently the owl has become thoroughly accustomed to activity. Twenty feet or so below the owl lurked Peter, Bruce, myself, and the lady of the house, although we spoke in muted whispers. At our feet gamboled several very active kittens, the progeny of a couple of adult barn cats. And there was Tig, a large and rather ferocious appearing "guard dog", who was nosing the kittens about and occasionally letting loose a bark. None of this hubbub caused the owl to as much as flinch, let alone open its eyes.

From my experience, there are basically two types of Barn Owl behavior regarding barn-roosting birds. Some, like this animal, are quite tame and not put off by people. They'll just remain perched high in the rafters or on the hay rail, and quiet observers - or even not so quiet ones - will not cause them apparent concern.

But there are plenty of spooky Barn Owls. These birds do not like intruders, and as soon as someone enters their dwelling they'll promptly catapult out the nearest exit hole and into the wide open outdoors. These are the birds to leave alone. A Barn Owl ensconced in the shadowy rafters of a barn is a safe owl. A Barn Owl flushed from its fortress during the day becomes far more vulnerable to those who would eat or otherwise relentlessly dog the bird. This is an almost strictly nocturnal owl, and forcing one to be exposed to hawks, crows, jays, the watchful eyes of Great Horned Owls and all manner of tormentors, some deadly, some just annoying, is not the thing to do.

Upon leaving the barn, I grabbed a couple of owl pellets. We retreated to another barn (owless) barn, and dissected one of them. Owl pellets are compact masses of indigestibles: fur, and bones. Several hours after swallowing a tasty mouse or vole, the owl commences to bob and gurgle like a frat boy that chugged too much beer, and out comes one of these surprisingly large pellets. The vole's skull is in the foreground, and various bones from the hapless victim can be seen projecting from its fur. An intact pellet is at the right.

The homeowner was very interested in these pellets and their composition, as any right-minded intellectually curious person ought to be. Just today, she texted me a photo of a pellet that she had much more painstakingly dismantled. It contained five (5!) vole and mice skulls! Apparently the owl is flourishing in its Knox County digs, and I hope there are many others in the area.
