Plummer’s Hollow after dark

The motion-triggered, infrared trail cam which the Scotts baited with a couple of venison rib cages really brought video pay dirt this month: coyote, bobcat, raccoons, opossum…

and a very hungry fisher (or possibly two different fishers — can anyone tell?).

March has been an active month for wildlife — especially after dark. The woodcock returned, and I heard a saw-whet owl calling, too, along with another creature of unknown identity. I captured it all on my portable digital recorder and included it as the first part of a podcast episode I called Creatures of the Night:

Pileated woodpecker

I shot this video from my front porch on Tuesday morning, June 8. Pileateds are common here because we have an old forest with lots of standing dead and dying trees full of their favorite food: carpenter ants. They’re really neat birds, and I end up mentioning them often in The Morning Porch. This video doesn’t capture their oddness in flight, but it does show calling, drumming, and excavating.

Walking the point count

We are counting birds for science, my mother and I. Plummer’s Hollow is part of the Bald Eagle Ridge Important Bird Area (IBA 32). We walk without words through the dawn forest — screech owl, worm-eating warbler — as the sky changes guard, our stops carefully measured: one minute to wait for our arrival to quit sending out ripples, then three minutes of counting every song and call and scanning holes in the canopy for wings: American kestrel, red-tailed hawk, chimney swift.

My job is to jot down the names as Mom whispers them: Hooded warbler. Scarlet tanager. Acadian flycatcher. Two red-eyed vireos. I watch the second hand come around, call time, and we walk the 500 feet to the next spot, taking three and a half hours to circle our mountaintop farm, ridgetop to ridgetop, half-way down the hollow and back. There are 16 points in all, the last on my parent’s front porch. Brown thrasher, ruby-throated hummingbird.

As I walk, I jot down notes for another list, one I know I won’t have the heart to finish: 25 things that make me sad. The oil spill in the Gulf, climate change, mountain-top removal, white nose syndrome, poverty and over-consumption… The way the land looked just 30 years ago, when I was a kid. How many more invasive species there are now. Our shrinking population of wood thrushes, the loss of that incomparable music, which this morning’s numbers should help document.

If we can’t learn to save, at least we can begin a more accurate accounting. Blue-gray gnatcatcher, red-bellied woodpecker, cardinal, common crow. This is our fifth year walking the point count. We hope to continue for decades, and find others to keep it going after we’re gone.

Three kinds of absence

Where nature’s concerned, it’s a cliché to say that every year’s different, but that doesn’t stop us from being struck by this simple truth anew each spring. This year in Plummer’s Hollow, certain absences seem especially worthy of note: chipmunk, garlic mustard, and wood thrush numbers are all down dramatically from last year. Our feelings about each decline, however, are quite different.

Chipmunks

Eastern chipmunk populations follow a several-year boom and bust pattern, and we’re currently in a bust. Last year at this time, you couldn’t walk ten paces in the woods without another chipmunk chittering alarm and diving for cover. This year you’re lucky to see two or three chipmunks per mile. Last Tuesday, a speaker at our local Audubon chapter’s monthly meeting, Dr. Steven Latta from the National Aviary in Pittsburgh, confirmed my suspicion that the chipmunk cycle is tied to the acorn cycle.

Oaks fall into two sub-genus clades: the red oak group of species, which take two years to produce a crop, and the white oak group, which produce acorns every year — barring a crop failure. We have roughly equal numbers of each group on the property. Black, red, and especially scarlet oaks are common on the drier slopes, while chestnut oaks, which are in the white oak group, predominate on the ridgetops. In addition, the Larel Ridge part of the old powerline right-of-way that bisects the upper part of the hollow near the houses has turned into a scrub oak barrens, and scrub oaks are also in the group that masts almost every year — except this past year. Last fall was the off-year for the red oak group, and in addition, the unusually cold and wet conditions during pollination time last May led to a total crop failure of oaks in the white oak group. We didn’t see a single acorn on the mountain. The acorn failure was so widespread in the northeast, it even made the national news.

Dr. Latta’s talk was about Louisiana waterthrushes as indicators of riparian habitat quality, but he mentioned chipmunks in passing: they’re a major nest-predator for ground-dwelling birds, he said, eating the nestlings whenever they find them. (It’s a good bet that ovenbirds, a waterthrush congener also found in the hollow, are heavily impacted by chipmunks during boom years as well.) Latta thought that chipmunk populations in western Pennsylvania, where his study sites are located, probably would’ve crashed this year anyway, due to disease, but he felt that the natually cyclic nature of acorn production by the red oak group is behind the fluctuations in chipmunk numbers.

So this year’s dramatic decline in the chipmunk population is natural then, and therefore nothing to worry about, right? Well, I don’t know. Nothing is ever that simple where ecology is concerned. Oaks are far from the only mast-producing tree or shrub in the woods — if they were, there wouldn’t be any chipmunks right now. As the example of nest predation shows, chipmunks, like squirrels, are resourceful omnivores. Maple and birch seeds may be a far less nutritious substitute for acorns, but they’re plantiful as hell. The dramatic, region-wide increase of black birches and red maples as a percentage of forest cover in recent decades must help cushion chipmunk populations to some extent.

Then there are hickories: once a major component of Appalachian ridgetop forests such as ours, and perhaps again in coming decades as the forests age: hickories are very slow-growing trees. American beech and eastern hemlock, by contrast, will be dropping out of the mast-tree equation as they succumb to an introduced blight and insect pest, respectively. (Beech bark disease has yet to hit Plummer’s hollow, but we figure it’s probably only a matter of time. Most of the mature American beeches in the northern counties of Pensylvania have already died.)

By far the biggest change to our forest in the last hundred years, however, was the almost total loss of the American chestnut due to the devastating effects of the Asian chestnut blight. We do have plenty of sprouts, which occasionally get big enough to flower and bear fruit before succumbing to the blight, and who knows how many more sprouts are eaten by the deer, so it’s safe to say that Plummer’s Hollow must’ve fit the Appalachian mold. A hundred years ago, chestnuts would’ve formed an almost unbroken carpet on the forest floor every year. It will be centuries, probably, before a blight-resistant chestnut re-colonizes the forest, and in the meantime, populations of rodents such as chipmunks, squirrels and mice, and who knows how many other wildlife species, will remain especially vulnerable to acorn crop failure as climate change brings more frequent wet Mays and late frosts.

This is a good example of how ecosystems lose resilience with each decline in biodiversity. In the case of chestnuts, their habit of flowering in June after all frost danger is past made them a more dependable mast species than, for example, the chestnut oaks. And while oaks are wind-pollinated, and therefore especially vulnerable to weather conditions, chestnuts are insect pollinated. My brother Steve and I happened upon a rare grove of flowering American chestnuts in a clearning in a nearby state forest last year, and we were astonished by the number and diversity of long-horned beetles swarming over their fuzzy yellow inflorescences. Steve is a beetle collector who has spent a lot of time in tropical forests, and he said he’d never seen such a concentration of Cerambycidae anywhere. Their numbers on that particular day might have simply been a reflection of the age of the surrounding forest — some ecologists consider long-horned beetle diversity to be an index of forest age, since their larvae live in dead trees. But we found it sobering to realize just what an insect bonanza must have been lost with the functional extirpation of the American chestnut.

Garlic mustard

Garlic mustard is an alien invasive species that first appeared in the hollow some fifteen years ago. It’s uniquely shade-tolerant, allowing it to compete with native wildflowers already under seige throughout the northeast by white-tailed deer. But this year, for the first time, we’ve noticed a decline in the number of flowering garlic mustards. We’re not sure what to attribute this to, and expect that, like the chipmunk decline, it’s only a temporary thing — though we’d love to be wrong about that. I had originally thought that perhaps last spring’s wet weather inhibited pollination, and perhaps it did, but that wouldn’t explain the decline in flowering stalks this year; it’s a biennial.

Like many non-native plants, garlic mustard is invasive because it has escaped the control of whatever insects, herbivores and diseases kept it in check back home (Europe, Asia, and North Africa). It can take a long time for native insects and diseases to adapt to an invasive plant species and rein it in, and in the meantime it can cause all sort of ecological havoc. Here’s how the National Park Service’s Alien Plant Working Group summarizes the case against Alliara petiolata:

Garlic mustard poses a severe threat to native plants and animals in forest communities in much of the eastern and midwestern U.S. Many native widlflowers that complete their life cycles in the springtime (e.g., spring beauty, wild ginger, bloodroot, Dutchman’s breeches, hepatica, toothworts, and trilliums) occur in the same habitat as garlic mustard. Once introduced to an area, garlic mustard outcompetes native plants by aggressively monopolizing light, moisture, nutrients, soil and space. Wildlife species that depend on these early plants for their foliage, pollen, nectar, fruits, seeds and roots, are deprived of these essential food sources when garlic mustard replaces them. Humans are also deprived of the vibrant display of beautiful spring wildflowers.

Garlic mustard also poses a threat to one of our rare native insects, the West Virginia white butterfly (Pieris virginiensis). Several species of spring wildflowers known as “toothworts” (Dentaria), also in the mustard family, are the primary food source for the caterpillar stage of this butterfly. Invasions of garlic mustard are causing local extirpations of the toothworts, and chemicals in garlic mustard appear to be toxic to the eggs of the butterfly, as evidenced by their failure to hatch when laid on garlic mustard plants.

So in this case, we’d love the current decline to turn into a long-term trend, but we suspect that it’s really only a temporary set-back.

Wood thrush

Where wood thrushes are concerned, however, I’m afraid this year’s virtual absence of singing thrushes in the woods near the houses, while probably in part incidental to where territory boundaries happen to have fallen this year, actually is part of a long-term decline — and one which, in contrast with garlic mustard, we do not welcome. Their ethereal, elegiac-sounding calls at dawn and dusk, from May through July, are something I look forward to all winter long, so it’s very sad to think that we may never again experience a woods ringing with thrush song as we did back in the 1970s.

In one of my mother’s nature columns for Pennsylvania Game News magazine, Minstrel of the Woods, from the July 2000 issue, she described the way things used to be here:

One July evening, along the Short Circuit Trail, I counted three wood thrushes singing at the same time, each song coming from a different direction. On other summer evenings my walks take me from one singing wood thrush to another as I move in and out of a succession of thrush territories.

Wood thrushes are a neotropical migrant species declining throughout their range for a number of reasons. One study I recall reading a few years back looked at the effect of acid precipitation on nesting success in upstate New York. Like all birds, wood thrushes need calcium to build their eggshells, and for a forest-nesting species, this means mainly snail shells. Appalachian forests have a huge natural abundance of land snails in the forest litter, but in many places now those snails, like so many other things, are in decline. Several studies have linked acid deposition from coal-burning power plants to the decline of land snails, especially on unbuffered mountaintop forests. The New York study found a direct correlation between the amount of acid deposition and the nesting success of wood thrushes. Needless to say, acid rain is a big problem here in Plummer’s Hollow — we’re due east of the biggest concentration of coal plants in the northeast.

But that’s only one possible factor that’s been linked to wood thrush decline. Most ecologists agree that the biggest general contributor is the continent-wide fragmentation of forests by roads and development, and the consequent increase of edge habitat at the expense of interior forest habitat. Wood thrushes, like many other neotropical migrant songbirds, are vulnerable to nest predation by edge-dwelling species such as brown-headed cowbirds and a long list of others, as my mother’s column ennumerates: “blue jays, common grackles, American crows, gray and southern flying squirrels, chipmunks, least weasels, white-footed mice, black rat snakes, sharp-shinned hawks, raccoons and pet and feral cats.”

Large, older forests such as we have in Plummer’s Hollow are the most secure stronghold for the species, which is why we find their three-decade-long decline here so discouraging: it may well reflect the global fortunes of the wood thrush. But assuming that we’re seeing some of the same thrushes or their offspring every year, the decline might also be due to local conditions. In particular, I wonder if the dying off of our mountain laurel is playing a role? Wood thrush are mid-level nesters, and laurel is the dominant shrub in most of the older forests on the property. But in just the past five or six years, it’s thinned dramatically, with the death of many individual bushes and some entire stands. Very few laurel bushes are without at least some dieback, even those out on the powerline, which initially seemed more resistant to whatever blight is responsible. We have yet to find out anything definitive about the dieback from botanists in a position to know. A couple of foresters we talked to about it seemed to wonder why we even cared about a species that can inhibit the sprouting of trees.

This is just speculation, of course, but the literature on wood thrush population decline is quite definitive about the vulnerability of their nests to opportunistic predators. Anything that makes the nests more visible can’t be good. Overbrowsing by deer is another factor in play here, and it’s the reason why we have so few shrubs other than laurel and witch hazel for the thrushes to nest in. Maple-leafed viburnum has spread a little in recent years, as effective hunting has diminished the size of the deer herd, but we have yet to see, for example, any hobblebush here.

Do the thrushes themselves notice their decline, I wonder? That’s doubtful: the longest-lived thrush on record, according to my mother’s column, only made it into its ninth year. But to me, the pure tones of the lone wood thrush that I hear a couple times a day from my front porch, usually at a distance, sound especially elegiac this year. Someday I’m sure we will look back on these years of habitat degradation and decline as golden years, too, compared with what is yet to come.

Later: And now having written and published this post, two wood thrushes are singing outside my front door! Go figure.

Christmas Bird Count 2008

by Mark

The Culp CBC circle administered by Juniata Valley Audubon. Block #5 is our section of Brush Mountain.

On Brush Mountain, Christmas Bird Count — always on a Saturday in mid-December — has normally been bigger than Xmas (the one with Baby Jesus and all that) itself. 2008, the 30th year we have participated in the Juniata Valley Audubon Society’s Culp Count, was no exception. I mean, Christmas itself is OK, what with all the cookies, carols, coffeecake and pagan revelry, but at heart it just isn’t as fun, at least for 3/5ths of the Bonta family, as a day of dawn-to-dusk hardcore birding in any and all weather conditions, followed by a potluck count supper at the Hoyer’s on down the mountain.

DISCLAIMER: The 2/5ths comprising Dave and Dad are not in the ‘hardcore’ cell; we’re talking about Mom, Steve, and tu servidor, who this year drove his butt off to make it up in time from Mississippi, where he coordinated the 5th annual Dahomey-Great River Road CBC the prior Monday (94 species).

AUTHOR’S NOTE: The following account is written largely in birder slang, of the North American sub-dialect. Confounded readers would be well advised to spend more time with birders, who generally make good buds, pish a lot, and are great conversationalists, as long as you don’t change the topic (from birds, of course).

8 PM the night before (December 19): the ice storm has fizzled out, the wind is howling on the ridge, and a few stars are visible. Steve croons his daughter to bed in the guest house, and then he and Mark discuss possibilities and strategies for the next day. They toss around the vague idea of stumbling out around 2 AM, when Nature calls, to listen for owls (doesn’t happen). We’ve come a long way from the early counts of 20 or 25 species, and the last time Steve and Mark collaborated on this CBC, we got an all-time high of over 40 species for the mountain and surrounding areas. This year the stakes are higher — we have a new search strategy, and overall the Culp Count has been getting record high numbers of species, with 67 in 2008. We are at the far northwestern edge of the Count circle (15 miles in diameter, a standardized size and shape for all CBCs), which includes Sinking Valley as well as Canoe Creek State Park, where the lake, when not frozen, can yield up to a dozen species of waterfowl. Privately, Mark figures we can get 50 species in our area, and hit 70 for the Count. But he doesn’t voice these sentiments, for he feels this could easily jinx the effort. Some birders are quite superstitious-why jeopardize an effort that already involves weeks of supplication to the feeder spirit, the weather gods, and the different generic Roman deities that preside over the birds themselves?

A good CBC is all about strategy, and particularly knowing when to hit the good areas — the ones most likely to contain the birds you might or might not get. Strategy is also about knowing which areas to avoid (those frozen woods populated only by chicakdee/titmouse quartets), how long to spend in a certain area, and whether or not to indulge the urge to come back by the house for a sit-down lunch. For other birding groups, more driving than walking takes place; for the Bonta family, driving is the exception and only resorted to once all the good walkable areas have been hit.

Pre-dawn, Count Day (December 20): We gobble cake and swill coffee. Mark stuffs a pack and heads off to the top of the powerline on Laurel Ridge to listen for owls. Steve gets ready to head off for ‘Margaret’s property,’ a swath of east-facing woods once inhabited by our former neighbor Margaret McHugh on the Plummer’s Hollow side of Sapsucker Ridge. The strategy is for them to cover the best habitat on the mountain first — the thickets of wild grape and Hercules’ club where most birds on the mountain that aren’t at the feeder tend to hang out in the winter. Mark’s plan is to bird the thickets on the edge of Sinking Valley along the base of the mountain all the way up to the Hunting Lodge, another property three miles southwest. By late morning, they will know where they both stand species-wise, and thus what to do with the rest of the day. Mom, meanwhile, will bird the trails between the house and the Far Field, while Dad and Dave keep a watch on the feeder and the granddaughter, who herself is on the lookout for Little Green Men.

Before 7 AM: Mark has hooted at three owl species to no avail, so he slip-slides his way down the powerline toward Sinking Valley, mindful of ice on the ground; the temperature is 24 degrees, and the heavy cloud cover affords only the slightest glimpse of sunrise. Heartstopping small planes explode from the surrounding trees, gobbling and creaking their way down off the mountain, turkey after turkey, only to alight further down and take off again; stop the count at 19. Turkeys are ‘where you find them,’ as birders say, so it’s a good bird to tick off early. They later became an annoyance, with the females flying up into nearby trees to investigate Mark’s pishing. Damned turkeys. Then, right on cue, a screech owl quavers from a thicket to the north, while a great-horned owl hoots from somewhere to the south. Mark calls the house to relay the good news and light a fire under Steve, still munching. That’s right! For the first year, the Bontas have gone high-tech, with cells all around to increase efficiency and in case of a life-threatening birding accident, or just for gloating. (The emergency number for a junco attack is 114.)

Steve’s morning: He pishes and crunches his way through the thickets on Margaret’s former property, flushing typically high numbers of cardinals, juncos, Carolina wrens, and white-throated sparrows. Birch catkins and other gourmet food bring out the pine siskins by the hundreds. Pileated woodpecker is a tick, a raven croaks down the ridge, and the one that got away for the day is the common grackle, possibly heard. Mark, whose grackle numbers in Mississippi were over 10,000, had a hard time getting his mind around the local exoticity of the species, but, as the youth say, whatevs.

By the way, we’ve gotten thoroughly tired of including the complete names of a bunch of these species, so the reader will note a certain liberty with over-lengthy monikers. We figure the birds themselves really couldn’t care what they’re called. (We could be wrong about that — possibly the Baltimore oriole’s numbers are increasing as a direct effect of regaining its name after years of being insistently mislabeled ‘northern oriole.’ Some data appear to suggest that this may indeed be occurring.) Anyway, if the reader is a stickler for complete and proper English nomenclature, see the official checklist.

Steve picks up two species we don’t get most years, a lone purple finch and a yellow-bellied sapsucker. It later turns out that no one else in the count circle gets a PuFi. One of the cardinal rules (pun intended) of CBCs is never to assume that someone else will get a bird, and always make the extra effort to chase after every fleeting gray or brown form (CBC birds come in both colors — sometimes, if you’re lucky, on the same bird!). Give 110% for the team, all that jazz. (This is about as close as the Bonta clan gets to team sports, in case you’re wondering about the choice of language.)

Once the tangles are birded, Steve drops down into the hollow and follows the road to the bottom. Hollow birds are a bit of a different guild, and one expects golden-crowned kinglets, brown creepers, winter wrens, and the like. By 11, he’s not gotten anything extraordinary, but has certainly been able to lock up several species that weren’t necessarily givens. He calls Mark.

The Feeder: On a good year, the feeder gives you some security that no matter how shitty the count in the woods is, you will still get the lone whatever that’s been hanging out at the feeder for the last couple of weeks, instead of Papua New Guinea or wherever it would rather be if its navigational equipment had been functioning correctly. This year, the star bird is a swamp sparrow, only exotic if you live on top of a swampless Appalachian mountain. He makes his usual appearance, along with scads of pine siskins, goldfinches, a few mourning doves, woodpeckers, and a variety of other LBJs.

Mom’s morning: Mom is not a happy camper, because by a meteorological accident the swath she covers is still encased in ice, which means birds are close to nil. She does get the raven and a winter wren, but for the PM is content to dive into an opera and keep an eye on the feeder all afternoon. Dave and she also prepare varied chow for the evening feast.

Mark’s morning: The tangled and repeatedly logged woods at the base of the mountain along Sinking Valley are thick with generations of hunters’ tree stands, themselves a worthy topic for some cultural geographical graduate thesis. After a while, a tree without some evidence of a deer stand begins to look a bit naked and underdeveloped — the whole thing is reminiscent of some temperate-zone Kombai village after a speculative real estate crash. But deer there are, aplenty, and thankfully, there’s no active deer season at the moment. Blaze orange isn’t the best apparel for birding. Nobody out here but us birds-even larger numbers of cardinals, white-throated sparrows, and juncos than on Margaret’s Property, as well as a couple of the only robins seen on the count, and healthy numbers of woodpeckers: downies, hairies, red-bellieds, pileateds, and a flicker. And just about everything else among the suite of common birds — again, nothing extraordinary, but in the high twenties species-wise, by the time Steve calls.

On the importance of coffee: Birding without coffee is like coffee without a mug, or a dog without hair. Or a geographer without a well-refined grasp of the simile. Steve is caffeine-free, so he calls all jolly and happy to see what’s the plan; Mark is pishing listlessly and swilling some thermos brew, waiting for the effects to kick in to get that coveted second wind so important for the second four hours of effort. Steve is going to head out and bird some areas along the tracks and the Juniata River, while Mark quickly hits the normally barren and sterile Hunting Lodge property. Combined, they’re a little over 30 species. A little trail mix, and on to Phase Two.

Steve hits the lowlands: There’s an old pond that’s good for a mallard flock, flush up agin the mountain, between a steep field and the railroad tracks. He then strikes out across the main road over to some random slashed-apart bottomland woods behind the Tyrone sewage treatment plant, and bingo! Once again, the birds are where you find them. The slash along a short stretch of powerline yields another big species for the day, a ruby-crowned kinglet, most of whose cousins, aunts, uncles, and assorted friends and relations have winged it down to warmer climes. Good numbers of golden-crowned kinglets as well, and the first winter wren for him, the hollow having been Troglodytes-less. A kingfisher takes off from heated effluent waters, and a great blue heron croaks its way off up the river. In the past, we’ve gotten yellow-rumped warbler and blue-gray gnatcatcher here — there’s something special about the place that only birds can appreciate, perhaps something to do with that strange affinity they so often tend to have for sewage treatment plants.

Mark is pleasantly surprised: The mountain is higher over here, and the ice line is farther down it. Unfortunately, he finally runs into a firmly posted bit of property on the valley-side tangles, right in the midst of some serious ‘birdage.’ So he backtracks and goes up a side hollow, emerging at the unposted hunting lodge property, with some brush, a farm pond, some old outbuildings, and a house. No one around, but a lot of bird noise. Hermit thrush and tons of ‘junkiters’ (as a now-deceased Valley neighbor had it) and goldfinches, along with scads of other common species. Now, what you have to understand here is that the hunting lodge, despite being one big Hoss’s all-you-can-eat buffet for up-and-coming white-tailed deer, is usually sterile, i.e. birdless. But this time, It’s Different. With dramatic music playing in his head, Mark tops a rise and catches flashes of non-blue jay blue: bluebirds blooping around the mucky, stubbly field. Another surprise is a lone cedar waxwing, which ends up being one of only two or three for the whole count. The mixed flock has hundreds of birds in it, including surprising numbers of white-breasted nuthatches, a northern flicker, and (incidental to the flock) three explosive ruffed grouse. (Grice?)

Interlude: Little do they know they have already reached 40 species for the day. Mark crashes back through a mile of iced tangle with little avian activity, retracing Mom’s steps with similar luck. As the noon factory whistle blows, he stops briefly at the house, foregoing a real lunch but not more java, and heads on down the hollow to a rendezvous with Steve. By 1:00, they are in Mark’s truck with a short list of places to go and species to see before dusk. Having exhausted the mountain, they will attempt to clean up another ten species in the greater Tyrone metropolitan area.

Slowdown: Three trash birds are always a given once you leave the mountain fastnesses: rock pigeon, starling, and house sparrow. The first is wheeling around Tyrone in the form of a majestic flock; the second is present in small numbers; the third becomes quite difficult to locate. We stop behind the hardware store where a bush is sure to have them, but no luck. With prospects of locating this species becoming grim, we cruise down toward Steve’s house, finally finding a bunch in a bush by a church. Tick.

Otherwise, we hit the practice fields behind the high school. Virtually nada, and nothing new. Deep hemlock forest at Reservoir Park. Nada. Random bottomland woods around Bellwood. Nada. Finally, as it appears that the afternoon will yield only frustration and heartbreak, we stop at the Grazierville exit off I-99 and find a promising and unbirded marsh, some sort of mitigation wetland cheek by jowl with the Little Juniata River, sandwiched between the interstate, the river, and Old Rt. 220. Of such wetlands are legends born. In our case, the birdage is rich, ripe, and fulfilling, and we got three new species: Cooper’s hawk getting chased by a kestrel, and a flock of Canada geese finally getting off their butts and leaving the Tyrone Reservoir (which is slightly outside the count circle) to wing obligingly into our count area.

Thomastown and the sewage treatment bottomland woods yield nothing new, and with multiple recounts we agree on a total of 46 species for the day – the highest yet for the family. Without much wind and clear weather, we appeared to have lost our chance for eagles (both are seen in December flying down Sapsucker Ridge) or gulls, while both northern harrier and sharp-shinned hawk got by us as well. In addition, the only south-bound straggler we logged was the ruby-crowned kinglet; years in which warmth has lingered later have yielded catbirds, towhees, and suchlike dickie birds.

Count supper: Post-Christmas Bird Count letdown doesn’t settle in just yet. First, we must hie ourselves to the Hoyer’s. Back in the day, we met at the Grange Hall out in Sinkin’ Valley, and potluck meant many cheesy casseroles with a bare hint of green growing things. The earliest counts that I remember featured now-deceased Audubon stalwarts such as Al Burd and Truth Close as well as a chapped and apparently frostbitten John Orr, local uber-birder who could generally be counted on to supply some rareties. Several generations have come and gone, it seems, with the venue changing (for the way better) and the food now bordering on gourmet.

The Hoyer’s is a retirement shack in the woods capable of comfortably seating 30-plus. Who could have known? Close to three dozen plain folks getting together to celebrate the counting of birds – in one way or another, the Count Supper is repeated across North America during the holiday season, a unique type of cultural event. I think of the chili, beer, and wine we enjoy at Dahomey Wildlife Refuge headquarters in Mississippi, and imagine how the foods and settings must vary across the continent. What do the presumably unplain gentry of Manhattan dine on after their count, presumably focused on Central Park and giant landfills? How many counters get together at subtropical beach locations? How many eat at McD’s or other such exclusive venues?

As for Culp, we got it all and then some. A roaring fire made with a very real-looking gas log, in a massive central chimney place. Gleeful small children (a manageable flock of two) hoarding stuffed animals and chasing each other through towering legs and past temptingly breakable glass and porcelain trimmings. Birders and birder-others (probably more of the latter) holding forth about this and that. And after thirty years, a familiar face — John Orr, who has been long absent from these events, proving that the CBC itch never stops itching.

The spread is fabulous, with eggplant making an unusual vegetable entree, and other healthy stuff aplenty. Plus baklava. Seconds. Thirds. Groaning.

And now, the moment we’ve all been waiting for:  Most count events end with the compilation of data. What a letdown it is when the day ends at dusk and thanks to inclement weather the supper is cancelled and the data are emailed. Calling them out live to the compiler is a visceral experience if you’re hardcore — indeed, it’s nearly a religious experience (call-and-response). Heidi Mullendore is the compiler this year, and she reads from a woefully incomplete checklist that leaves lots of room for additions at the end. We are handicapped, as the Bonta family tally sheet was forgotten on the kitchen table, purportedly by Mark. After the common species comes the drama, when each count group announces the species they got that aren’t on the list. This year, these go on and on, with numerous waterfowl, a golden eagle, and, probably a first, a short-eared owl. Then, the magic moment — the total number of species. This year, it’s 69. A new high, albeit tentative, pending any confirmations the compiler requests.

The compiler reserves the right to accept or reject unusual species, part of the attempt to keep the ‘science’ in ‘citizen science,’ as Audubon calls these types of activities. In some cases, counters, regardless of their expertise, are asked to fill out Rare Bird forms, and occasionally even when these are accepted by the count compiler, the regional compiler — an august character whose purview includes counts in a multi-state area — nixes the species. This can be quite frustrating for the counter involved: I remember like it was yesterday the time my racket-tailless blue-crowned motmot was rejected solely on the grounds that it was a blue jay. I was only 4, but still. It hurts.

Trendwatch: And finally, in conclusion, we need to make all this relevant and significant, for otherwise we have simply penned a needlessly lengthy and superfluously verbose blogpost that will not stand the test of time and rather be forgotten like yesterday’s underwear. So, the question is, what’s important? We would say that it is the fact that the Culp count is getting higher numbers every year. Like everything else that is different and involves things that fly, we suspect that we have Global Warming to thank, sorry, blame. We are pretty sure that GW is causing everything to go higgledy-piggledy, which increases avian diversity, except for evening grosbeaks (mustard birds) which appear to be disappearing, and a few dozen other species we didn’t see so they don’t matter.

However, it is altogether possible that there were more birds than ever this year because the Dark Cloud in the East has lifted, and the minions of Sauron have dissolved into the morning mists. We’re talking about the other GW here and the Fall of Neocon. We are figuring that the birds have somehow sensed that a new administration will quickly act to save them and their habitats, as well as stop GW, rescue the world economy, and cause everyone everywhere to love each other and stop fighting endlessly over trivial, non-bird-related issues. Or at least lighten up a bit on the environment and make mountaintop removal punishable by death.

A third hypothesis, entirely untenable but included here for its laughable attempt to incorporate Occam’s Razor, has it that the Culp count species totals are increasing steadily because there are more people out counting birds. To disprove this is easy: I knew a guy whose cousin out in Iowa ran a count that had more people out every year, with less species as a result. So in the case of the Culp count it is easy to see that this hypothesis is false and should be discarded like yesterday’s underwear and Evolution.

So that’s it, then. Science is vindicated, Truth prevails, and 70 becomes the new 69 for the future of central Pennsylvania Christmas counting. For the meantime, let the post-Christmas Bird Count letdown commence!

2008 International Migratory Bird Day

indigo bunting in the rainIt was 46 degrees and raining when I awoke at 6:00 a.m., but the birds sang anyway, especially the two male Baltimore orioles competing for a female in our yard. I managed to count 19 species from our veranda and front porch before breakfast, including an eastern kingbird that had first appeared at the edge of First Field on Thursday. Later in the morning, carrying an umbrella, trying to protect my binoculars from the rain, keeping my feet dry, and staying warm, all while counting birds, was no fun. However, I added 15 more species to my list, including many singing indigo buntings in the field and wood thrushes in the woods. Worm-eating warblers, ovenbirds, black-throated green warblers, hooded warblers and even a black-throated blue warbler also sang. About the only birds I saw were those in the fields. The rest I counted by ear.

After a rest and a change into dry clothes and boots, I went more happily out in the sunny afternoon. Down our road I walked to get Acadian flycatchers and common grackles. Then I climbed up to the former clearcut where I hit the jackpot — a migratory flock of warblers that included many American redstarts. I also heard both a cerulean warbler and a northern parula. By the time I reached home, at 5:30 p.m., I had 55 species — a respectable total for a solo performance. Then, after dinner, I looked at my mertensia patch for a ruby-throated hummingbird and there he was. And, right on schedule, our resident whippoorwill called outside at 8:45 p.m. As usual, the eastern towhees (13) and red-eyed vireos (12) were the most abundant species or at least singers. Hooded warblers won the warbler contest at eight, closely followed by American redstart (7). Wood thrushes (8) scarlet tanagers (8) and indigo buntings (7) also made a good showing, and I did have many wonderful sightings of the tanagers and buntings.
