Not a bog plant, but nonetheless interesting. We saw the old pods of this conspicuous plant nearby. It's Wild Cucumber, Echinocystis lobata. The spiny fruit are quite distinctive, as is its vining habitat.
To many plant enthusiasts, this is the creme de la creme of bog plants. Northern Pitcher-plant, Sarracenia purpurea, still looks good in the winter. The anthocyanins (colored pigments) in the leaves become bolder after the growing season, creating brilliant reddish-purple splashes amongst the soft lime-green beds of Sphagnum moss.Straight down the gullet of a pitcher. This is a carnivorous plant, one of few true plant carnivores in Ohio. These modified leaves are effective traps, and enable the plant to capture insects; effective sources of nitrogen and protein. In the bottom of the leaf pools rainwater, injected with chemicals produced by the plant that reduce bouyancy and speed digestion. Basically, if you are a bug and fall in, it will be hard to float, and your soft parts won't last long. Those stiff, whitish hairs lining the throat are retrorsely directed; that is, they point down. That's great for the bug walking into the trap, but very bad for the bug that wises up and decides to bail. Quite hard going against those hairs, you know.

Strange place for an owl...
Bruce Peterjohn, in his book The Birds of Ohio (2001) states "Their fall migration has never been well defined in Ohio". Probably true at the time Bruce penned those words, but it shows how fast our knowledge of a species can evolve. Almost entirely because of banding studies, we are learning much more of the southward movements of these furtive hooters.
But, surprises always await, and Laurie Boylan sent along a neat one recently. Her friend Audrey Dragony was exiting the Diamond Building in downtown Cleveland - at Superior and 12th - on October 27th, about 11:30 pm, and noticed a small brown lump on the sidewalk. A closer look revealed an apparently unhurt Northern Saw-whet Owl sitting like a little avian panhandler. Audrey had her camera - good work, Audrey! - and snapped the following photo.
"Hey bud, gotta bit of change for an owl down on his luck" At least he didn't have a sign saying "Owl will work for food - help a hooter in need"!
Audrey's sighting coincides with the beginning of saw-whet migration, and it's appearance in the cement jungle of downtown Cleveland isn't as odd as it may seem. Being hard on the shores of Lake Erie, many migrant birds crossing the lake hit shore here, and filter through the inner city. I've seen tiny postage-stamp downtown parks in Cleveland swarming with migrants in fall just after dawn.
Hopefully this saw-whet overcame its disorientation, picked up and moved on. It probably did. Thanks to Audrey and Laurie for sharing this interesting experience with us!

A Tough Little Hummer
As is I earlier said, it's good this hummer isn't Tundra Swan-sized or it probably would have dealt severely with Allen. While he was setting the trap, it waited impatiently nearby. Then it went through a brief, very brief, curiosity phase. I would too. After all, the normally unadorned feeder is now encaged in a large contraption built of wires. This sends up a red flag to the bird, and it flies briefly about, investigating the trap. Here, it cocks a tiny eye at the setup. Seconds later, we had it.Allen is reaching through the trap door and gently extracting the now caught hummingbird. The trap's a pretty cool device. Although intrusive in appearance, it seldom dissuades the hummingbirds for long. They are so fixated on the feeder that they'll fly right over, and buzz around the bars looking for a way in. Soon, they come to the open door and shoot right in to happily lap up sugar-water. Allen, watchfully waiting in the wings, triggers a James Bond-like remote control that causes the door to fall shut. And we've got it. And now is where experience kicks in. Becoming licensed to band these tiniest of birds is not easy, and requires gaining lots of experience and apprenticeships with other banders. Allen had this bird out of the trap and in the bag in seconds - not an easy feat!Ann, the homeowner, was very interested in her bird and very gracious towards us. She allowed Allen to set up a temporary hummingbird lab in the study, so we could work with the bird out of the cold. For its benefit, not ours. In addition to placing a tiny band on its leg, data such as wing length, body fat, molt and coloration patterns, bill corrugations, etc. are carefully gathered and recorded. And weight. Here's the weigh-in. Our champ is nestled in that soft little sack for safekeeping. This whopper tipped the scales at a robust 3.73 grams. That's about the same as a shiny new penny.
Of course, in the back of all of our birding-fanatic minds, we were hoping that it just might turn out to be an Allen's Hummingbird. Nothing like a new state record to get the blood going. No such luck, and these tail feathers tell the story. Note that there are ten, and each are numbered from the inside out. So, the outermost tail feathers (known as a rectrix) are number fives. In Rufous, the outer tail feathers are quite broad in comparison to an Allen's, which has very narrow ones in comparison. So, because of that feature as well as other characters we knew this bird was an adult female Rufous Hummingbird, Selasphorus rufus. And we were scarcely disappointed that it wasn't the hoped for Allen's. It's always a treat to see any hummingbird, especially a rare Rufous in mid-December in snow-covered Mansfield, Ohio.
One wonders what is going on in that Lilliputian mind, as she watches us with those inscrutable little eyes. Rufous Hummingbirds handle well, and remind me a bit of working with Northern Saw-whet Owls. They are unflappable, and seemingly not too put out by all of the gymnastics we put it through during the banding. Some of the most beautiful feathers in the bird world are the central throat, or gorget, feathers of hummingbirds. When the light hits just so, they gleam irridescently.
When the time came to let Ms. Rufous go, Allen let homeowner Ann do the honors. It sat in her hand ever so briefly, then shot off like a rocket emitting high-pitched chitters. Hummingbird expletives, probably. It got over any hard feelings quickly enough, and had returned to the same feeder we caught it at within 25 minutes. This same bird or one much like it was here last year about the same time. It will be interesting to see if it returns again next year. Now that it's been marked, we'll be able to tell. Thanks to Ann for letting us invade and work with her special visitor, and to Allen Chartier for lending his time and expertise.

Pine Warbler, Take 2
Tough Crawford County Pine Warbler. Probably not too many winter records of this species from the county that brought us the Bucyrus Bratwurst Festival. Maybe none, for that matter. In fact, I wonder why it would show up there as a winterer, when the closest place that they breed is probably Mohican State Forest, which probably does have occasional wintering Pine Warblers. But, there's plenty of big pines and hemlocks at Mohican, which is your best bet for finding them, even in winter. Crawford County is distinctly un-Mohican-like in regards to habitat. But, it looks like the blurry green in the background of Josh's photo could be the boughs of white pine, so maybe there's some nice conifers at this park that lured it in.
I wish I had time to pore over the records, and analyze all of the winter warbler reports from Ohio and nearby states. There seems to be no question that they are increasing. The bird above isn't too surprising, but Ovenbirds, Louisana Waterthrushes, Northern Parulas and the like are. Among the first and most obvious responders to changes wrought by global warming will be things with wings. In the case of warblers, we may see more lingering into winter far north of their usual haunts. It doesn't take much of a temperature increase to keep insects alive, and provide food, along with the feeding stations. I think we are already seeing some interesting and new responses among butterflies and dragonflies as conditions warm.
Thanks for sharing your Pine Warbler with us, Josh.

Christmas Bird Counts
Speaking of that 1956 Buckeye Lake CBC, the legendary Milton Trautman ws no doubt a participant. And Milt's name is on the list of the 78 people that have participated in at least 50 counts. I really thank Roger for assembling that, and Mike posted it on the website. Mainly because looking through those names allowed me to wax nostalgic and think back on many counts shared with many of those individuals. Many of whom are still out and active and doing CBC's to add to their total. At #1 is Ernie Limes at 246! That's a staggering number, and a benchmark that will be very tough to beat. I've done a far number, weighing in with 69, but I'd have to do at least six a year for 30 years to eclipse Ernie's amazing milestone. Don't see anyone on the horizon to threaten that record. By the way, next time you are on the Magee Marsh boardwalk, check out the plaque along the trail dedicated to Ernie and featuring his picture.
Skim through the list and you'll recognize many of the names. I did, and it was good to reflect back on field experiences with many of them.

Pine Warblers also eat seed. I remember being at a B & B in Tennessee a few years back in late winter, and several pines were frequenting the feeders.Thanks to Cathy for tipping us off about this bird. With all of the people that feed birds anymore, one has to wonder what rarities appear that no one ever hears about. There's probably a Golden-crowned Sparrow hitting someone's feeders right now...

Refuges and the Economy
Ohio's own Ottawa NWR tallied about 177,000 visitors in 2006, and they collectively pumped about $3.5 million into the local economy. At Ottawa, it's estimated that about $21 was produced in terms of of local economic input, for every $1 spent on the refuge by the Federales. This is an aspect of land protection that I don't think gets the due it deserves. We should take a longer view regarding large-scale land protection, and recognize that it benefits not only plant and animal populations, but humans as well. Also of interest is the conclusion that, at Ottawa, around $3.2 million was brought in by out of area visitors. Obviously, refuges drive ecotourism in a big way. I'd bet that similar figures would be produced for many nature preserves, wildlife areas, parks, etc.
The following nicely done article from the Refuge Watch blog summarizes things nicely:
Wildlife Refuges Help Local Economies
Back in 2003, the National Wildlife Refuge System celebrated its centennial anniversary with various events held around the country that showcased the amazing collection of 535+ refuges that formed the System. Many laudatory speeches were made at that time, including ones by former Secretary of Interior Gale Norton and President George W. Bush, during which they applauded the many benefits of the National Wildlife Refuge System. Now four years later, the Bush administration is pursuing its agenda to cut 565 jobs from the Refuge System — a 20% reduction — which will result in over 200 refuges having no staff at all and many visitor services and conservation programs ceasing to exist.
There is no doubt that the Refuge System is highly popular with the American public. Almost 35 million citizens visit the Refuge System annually, using the lands for recreation, education, and exercise. Yet there is an added taxpayer benefit to the Refuge System that is often overlooked — the economic boon that these lands bring to their local communities.
Yesterday, the U.S. Fish and Wildlife Service’s Division of Economics issued their “Banking on Nature 2006″ report, which details the many economic benefits that national wildlife refuges bring to their local towns.
According to the Service, the report “focuses on final demand, employment, income and tax revenue effects recreational visitors to refuges have on the economies of local regions. In addition to the economic effects of refuge hunting and fishing programs in local communities, it measures the economic impact of ‘ecotourism,’ the relatively recent phenomenon of large numbers of people traveling substantial distances to take part in nonconsumptive uses of the natural environment.”
The report clearly indicates that national wildlife refuges are a great value to taxpayers, returning about $4 in economic activity for every $1 the government spends.
Below is a quick overview of some of the more interesting results:
Recreational visits to national wildlife refuges generate substantial economic activity. In FY 2006, 34.8 million people visited refuges in the lower 48 states for recreation. Their spending generated almost $1.7 billion of sales in regional economies. As this spending flowed through the economy, nearly 27,000 people were employed and $542.8 million in employment income was generated.
About 82 percent of total expenditures are generated by non-consumptive activities on refuges. Fishing accounted for 12 percent and hunting 6 percent. Local residents accounted for 13 percent of expenditures while visitors coming from outside the local area accounted for 87 percent. Refuge recreational spending generated about $185.3 million in tax revenue at the local, county, state and Federal level.
Surveys show refuge visitors would have been willing to pay more for their visit than it actually cost them. The difference between what they were willing to pay and what they actually paid is their net economic value or consumer surplus. Visitors enjoyed a consumer surplus of nearly $860 million in 2006. Over $664 million of this amount (77 percent of total net economic value) accrued to non-consumptive visitors.
The “Banking on Nature 2006″ report features a breakdown of the economic contributions of refuges from every region in the System. One good sample refuge is Chincoteague National Wildlife Refuge. Chincoteague NWR is located in Virginia but has an economic area that includes both Accomack County in Virginia and Worcester County in Maryland. According to the report:
The Refuge had 7,485,286 visits in 2006. Non-residents accounted for 89 percent of all Refuge visits. Almost all of the visits were for non-consumptive recreation with saltwater fishing accounting for 145,200 visits and hunting accounting for 2,592 visits…
Total expenditures were $238.7 million with non-residents accounting for $232.4 million or 97 percent of total expenditures. Expenditures on non-consumptive activities accounted for 98 percent of all expenditures, followed by fishing and hunting at 2 and less than 1 percent respectively…
Final demand totaled $315 million with associated employment of 3,766 jobs, $94.8 million in employment income and $50.3 million in total tax revenue…
…for every $1 of budget expenditures, $155.42 of total economic effects are associated with these budget expenditures.
So for every $1 of taxpayer money, the local economy saw $155.42 in economic benefits. And this is just one refuge.
As Congress works with President Bush to reach a compromise on the budget stalemate, it’s important to remember that the National Wildlife Refuge System rewards American taxpayers in many ways — recreation, resource conservation, environmental education, ecosystem services, and economic benefits.Contact your representative and senators today, and remind them that you support a budget increase for the Refuge System. The annual increase that the Refuge System needs each year to keep up with inflation — $15 million — is what we spend in Iraq about every two hours. Americans can afford to invest more in this vital federal land system.

Ohio Bird Conservation Conference
This is our cast of speakers, each of whom was outstanding. From l to r. Dave Ewert of The Nature Conservancy spoke about migratory bird stopover needs, especially in the Great Lakes region and Ohio. While we often think of breeding and wintering grounds conservation, more thought and effort is needed to protect habitat along the corridors that migrants use. Dave knows more about this issue than probably anyone, and shared that knowledge very well.
Paul Baicich is an exceptional ambassador for getting birders involved actively in conservation, and speaks to the topic perhaps better than anyone. He has been a very positive example for me personally. That's what he did for us this weekend - delivered a message of activism and involvement, whether it be purchasing a duck stamp or lobbying for "lights out" programs for skyscapers.
Scott Weidensaul was keynote speaker and it wouldn't be possible to find a more apropos choice. On Saturday evening Scott delivered an incredible program based on his book Return to Wild America, a retracing of the incredible journey of Roger Tory Peterson and James Fisher 50 years prior. With the help of outstanding imagery, Scott took us to some of North America's icon natural areas, and talked about what they mean to Americans, and wildlife. We began the trip with Scott on the high bluffs of Newfoundland, teeming with Northern Gannets and other seabirds, and ended on massive cliffs overlooking the sea in Alaska, also abundant with birds. In between was a compelling story of the need to save what we have, delivered by perhaps the most eloquent voice advocating for nature. Scott's is a story that should be heard by everyone.
Chris Bedel's message was one of biodiversity, delivered in his always engaging and over the top enthusiastic style. The 14,000-acre Edge of Appalachia preserve in Adams County was his topic, and Chris educated us on the incredible array of life found there. Birds, wasps, lichens, mussels, plants, snails - you name it, Chris knows about it. "The Edge" is where the OOS has donated $10,000 for land acquistion, and it was good for everyone to hear from Chris that even though we've helped to protect birds, much other biodiversity comes with the package.
Amanda Rodewald kicked things off, fittingly, with an overview of her work with Cerulean Warblers. That species, as you may know, is the icon bird of the OOS. Cerulean Warblers have declined by an estimated 70% since the 1960's and fully deserve out attention. Amanda is somewhat of a rarity, in my experince, in that she is an academic researcher who can also convey her work to the general public exceptionally well. She is an enthusiastic and articulate speaker that doesn't go over our heads, but yet describes intense research work. Amanda spearheads studies on Ceruleans on their wintering grounds in the Andes of Venezuela, and among other things has documented the importance of shade-grown coffee plantations in the wintering ecology of this beautiful bird.At our Friday night get-together, Scott Weidensaul graciously signed many, many copies of his books. Here, Don "Donald the Birder" Morse gets an autograph.
The OOS and other friends presented Jen Sauter with this token of our appreciation on Saturday night. Jen is Executive Secretary of the OOS, and the driving force behind planning and executing these conferences among other things. It was the least we could do, and I wish we could do more to honor all of her contributions. Her gift is a signed painting of a Golden-winged Warbler by Jennifer Brumfield.
We also took the opportunity to recognize Cheryl Harner, president of the Greater Mohican Audubon Society, on the left. Cheryl has made real contributions in Ohio's conservation community, and been another driving force behind developing and implementing innovative efforts to further land protection and get people involved. We presented Cheryl with a hand-carved Wood Duck decoy created by Laura and Tim Dornan.
We also presented this check for $1,500 to Amanda Rodewald to help with her work on Cerulean Warblers. From l to r: me,, OOS financial officer Peter, Amanda, and OOS conservation committee chair Tom Bain, who also did an outstanding job as emcee for the conference.
Thanks to all of you who support the OOS and make it possible for us to support work such as Amanda's. In a digital fit display of bad manners, my camera somehow destroyed the photos I had of our presentation of a check for $10,000 to The Nature Conservancy for an important land acquisition project. Others took photos of that presentation and I'm hopeful someone will send me one so that I can share it here.

I was fortunate enough to see the bird myself last Sunday. Shortly after arriving at the spot and joining several other birders in the stakeout, I heard the grosbeak calling not far off. A minute later it shot right over our heads and landed near the top of a tall Hackberry tree, offering us stellar views. It appears to be a young male, not yet in the full pinkish-raspberry hue of an adult.
This is the spot. A weedy semi-wooded edge choked with non-native plants. All that green understory is Amur Honeysuckle, Lonicera maackii, a Eurasian invader that is now prolific in many regions of Ohio. This bush fruits prolifically and the shrubs are decked with red berries. That's apparently what the grosbeak is gorging itself on. Pine Grosbeaks are largely frugivorous (fruit-eating), and it won't run out of fodder here for some time. The issue is the poor nutrient content of honeysuckle fruit. Like vegetative M & M's, they look great and probably are tasty to birds, but are deficient in lipids and proteins. It's likely that a diet of such fruit lacks the necessary substances to sustain birds well when the winter weather gets tough.
Here's our guy. Large and confiding, Pine Grosbeaks are known for their docility and often can be closely approached. The typical modus operandi for this bird is to fly in from the south, and alight in the top of this small Hackberry tree just to the east of the gate in the above photo. There he sits, surveying his kingdom for a few minutes while the assembled throngs of birders ooh and aah over him. Then, like a meteor falling from the sky, he dives straight down into the thickets, presumably to engorge itself on berries. You've got to be there at just the right time; a number of birders have either missed it altogether - as I did my first visit - or have had to wait hours before King Finch made an appearance.
Pine Grosbeaks are northerners, birds of the vast boreal forest. They rarely stage irruptions southward in any great numbers, and only very rarely venture as far south as Ohio. The largest Ohio invasion ever was during the winter of 1961-62. That winter, flcoks or individuals were seen in a number of laocales, including an incredible flock of 100 near Akron. At least one bird made it all the way to Cincinnati. Interestingly, that year they began to show up in November, right around the same time this bird did. The record is not quite clear as to the last confirmed Ohio sighting prior to this one; either 1987 or the perhaps the early 1990's. In any event, this Pine Grosbeak was a spectacular find and has thrilled many of us.

Late hummingbirds are also appearing. One came to light today near Toledo, that appears to be our record late Ruby-throated Hummingbird. I got a call about another today at a Cincinnati-area feeder and will hopefully get photos soon. These late ones really need scrutinized closely, especially as most are females/immatures and often not readily separable from other similar species. Don't just assume Ruby-throated...
I also just received word of a very interesting Northern Saw-whet Owl that was captured at the Chillicothe banding station already sporting a band. This one has come a LONG way, and I'll get those details up here soon.
But, the showiest of all is an amazingly cooperative Sabine's Gull found at Huron on Turkey Day, November 22, by Mike Busam. Congrats to Mike for locating this bird and tipping everyone off. Because he did so, a great many folks have seen this beautiful small gull for the first time. Sabine's Gull is quite rare in Ohio, with only a few seen each fall, if that. Most don't stick like the Huron bird, either. These arctic breeders are highly migratory, wintering primarily in tropical seas off Africa and South America. Relatively few pass through the Great Lakes.
Upon arrival in downtown Huron and the river, one is greeted by mobs of Bonaparte's Gulls, making a cacophony of noisy squeaking buzzes. Masses of Bonies are always great places to look for rare gulls. Indeed, this horde contained at least two Little Gulls, according to other reports.
Adult Bonaparte's in flight. These small gulls are quite striking with their flashing white leading edge to the upper wing, and bouyantly graceful flight. They are not the trash-eating McDonald's scavengers that some of their larger brethren are; Bonies are highly piscivorous, deftly picking small fish like Emerald Shiners from the water.
Adult Bonaparte's Gull at rest. A strikingly beautiful bird, even without the black hood they sport in breeding plumage. The best is yet to come, though.
Ground zero at Huron, the terminal point of the municipal pier. The lighthouse is a great place to watch birds moving past on the lake. I've spent countless hours out there, many of them in November. Conditions are often not very pleasant, with blustery winds and freezing temps. Such was not the case today, with hardly any wind and low 40's. Quite balmy for a late November Lake Erie day! This is the spot that the Sabine's Gull is fixated on, and it made frequent flights right around the lighthouse, sometimes flying within ten feet of us, or roosting on the water nearby.
Sabine's Gull, Xema sabini, at rest. Doesn't stand out nearly as much as when in flight, as you'll soon see. About the size of a Bonaparte's Gull, the brown mantle of the Sabine's is distinctive, as are those blotches of brown that extend forward onto either side of the breast. This may be the only gull named for an astronomer. Sir Edward Sabine was an astronomer who accompanied an 1818 expedtion into the Arctic, and helped discover the gull. His brother, Joseph, named it in his honor.
I was fortunate in running into my friend Brian Zwiebel upon arrival at Huron, and we were able to spend the afternoon birding and admiring the Sabine's Gull. Brian is a topnotch professional shooter, as you can see from the above photo, which is his. Although often close at hand, getting crisp in-flight shots of the bird was not easy. As befits such a long-distance migrant, the gull is quite effortless on the wing, and deceptively fast. The upper wing pattern is unmistakable and stands out from great distances. The slightly forked tail is also characteristic and adds yet another interesting touch to an already visually stunning bird. If you haven't made the pilgrimage to see this Sabine's, I'd go while the getting is good.
Thanks to Mike Busam for finding this bird and communicating it to all, and to Brian for graciously letting me use his photo.

Butterfly Named for Ohioan
Tucson, Arizona Published: 11.23.2007
GAINESVILLE, Fla. — A butterfly species discovered in a Florida museum has a new name after an anonymous bidder paid $40,800 for naming rights in order to honor a woman who died in 1972.
The butterfly's common name will be the Minerva owl butterfly. It's being named after the late Margery Minerva Blythe Kitzmiller of Malvern, Ohio.
While the bidder's name was not disclosed, the payment was made on behalf of Kitzmiller's grandchildren.
The butterfly's scientific name will be Opsiphanes blythekitzmillerae.
University of Florida researchers George Austin and Andrew Warren discovered the new species while looking through a butterfly collection at the Florida Museum of Natural History in Gainesville earlier this year. They found it was misidentified as an example of another species.
The 4-inch butterfly is brown, white and black and lives in Sonora, a Mexican state bordering Arizona. Proceeds from the auction will go toward further research of Mexican butterflies.
Beverly Sensbach, director of development for the museum, said Kitzmiller's grandchildren wanted to honor her through the name of a beautiful butterfly because she was "an extremely creative person who wrote poetry, played piano and sang."
The rights were sold via an online auction. Warren had said before the auction closed that the researchers were hoping to raise at least $50,000, which would fund two years of work in Mexico.

Everything is Rare, Somewhere
American dove attracts twitchers
The American mourning dove has caused a stir
A dove spotted only a handful of times in the British Isles has drawn dozens of bird watchers to North Uist.
The American mourning dove was first seen by Brian Rabbitts about three miles (4km) from where he previously saw one in 1999.
Wildlife guide Stephen Duffield said more than 100 twitchers had flocked to the Western Isles to see the bird.
The British Birds Rarities Committee said it was aware of the sighting and was awaiting a recording.

The leaves still impressed. The orange-red mist is the foliage of Sourwood, Oxydendrum arboreum, our only tree in the heath family. It grows in the poor soils of rocky ridges, such as this one. The pale yellow leaves are those of Chestnut Oaks, Quercus prinus. It is another tree of acid ridgetop soils, and festoons sites like this in abundance.
That big, left-listing trunk is a Chestnut Oak. This photo really demonstrates the rocky nature of the ground they spring from. Soil on sites such as this is thin, and poor. A Chestnut Oak of this size will have taken lots of years to reach such girth. The bluish-green circular patches on the rocks are a type of lichen, Flavoparmelia baltimorensis. Lichens begin the long, long process of breaking down sandstone rock.A Sourwood leaf adds an electric burst of flame to the somber tones of the bark of a Chestnut Oak. This old tree is garbed in thick coats of lichens, of several species. I believe these grayish foliose lichens are in the genus Hypotrachnya. Lichens are the products of commensal relationships between algae and fungus, collectively forming the organism we see above. They are hyper-sensitive to air pollution and are amongst the first organisms to vanish if air quality suffers.
North meets south in this special place. The rocky grotto in the backdrop is choked with a river of Great Rhododendron, Rhododendron maximum, in such profuse tangles that one might be excused for listening for Swainson's Warblers. This is nearly the northernmost outpost for this Appalachian heath. Overshadowing it are plenty of Eastern Hemlock trees (Tsuga canadensis), a northern tree nearing its southern limits here.
The stunted, twisted trunk of a Mountain-laurel, Kalmia latifolia. This smaller relative of the Great Rhododendron also has thick, fleshy evergreen leaves and is still bright. The gnarled trunks resemble wild bonsai, especially this one, as it springs from a lush bed of pincushion moss (genus Leucobryum).
The last wild flowers of the year - Witch-hazel, Hamamelis virginiana, right on schedule. November is the time to look for the spindly pale yellow blooms dangling from the barren branches of these small, multi-trunked woodland shrubs. It's easy to miss them, and easy to wonder how you missed them once you see them.

Northern Saw-whet Owl Invasion Update
And man, I was glad some owls turned up last night! We had a rather celeb cast on hand, partly on my invite, and we would have felt bad if no owls showed. They did, fortunately, with three birds being caught. One had been banded the previous night; the other two were new birds. This brings the total capture since October 10th - 28 nights of banding - to 93 different birds! That's over three an evening, on average. This is definitely the year os the saw-whet.
Measuring an owl's foot. Not for a shoe fitting, but to gather additional data that might help in sexing birds. Sometimes, telling males from females is not that easy and banders are still learning ways to distinguish the sexes. These owls are incredibly tolerant of people, and the banding process. Generally, they just lay there and look at the people with a rather curious attitude. I suspect that for many owls, we are the first humanoids they have ever seen, and that in conjunction with their calm dispositions leads them to view us rather peacefully. Sometimes, upon release an owl will be placed on someone's arm. There it will sit, sometimes for several minutes, before deciding to fly back into the dark forest.Something rather amazing that we've found is that saw-whets seem to greatly enjoy having their necks rubbed. That's what is going on here, and the owl has hooded its eyes and is pushing back into the fingers of the petter, much in the manner of a cat. I found that when I gently rubbed the sides of their heads, they also relished that feeling and would push hard against my fingers and practically become entranced. No, I don't think the micro-owls suffer much from their banding experience and I'd be surprised if their heart rates even elevate a beat.
