Abingdon 2022: 1

My base of operations for this year’s birthday romp was Abingdon, Virginia.

new parklazy riverFirst up was Clinch River State Park, newly elevated to state park status and therefore a little lean on amenities. The lazy river doesn’t mind.


Best critter for the entire trip was a Lace-winged Roadside-Skipper (Amblyscirtes aesculapius) just a bit outside its range in the guidebooks, nectaring on Bear’s Foot (Smallanthus uvedalia).

number 2trestleRain mid-day curtailed plans to hit another state park, but later in the afternoon I walked a bit of the Virginia Creeper Trail, one of the first rails-to-trails conversions. This trail crosses numerous stream gorges via wooden trestles—quite dramatic. The watershed here is the Holston.

look out belowThis view down into Berry Creek is from trestle #3. From trestle #4 in Watauga you’re eye level with the top of a substantial American Sycamore.

Clifton Institute bioblitz August 2022

no, over hereboth sides nowI took part in a Clifton Institute bioblitz on the property of an institute sponsor. I didn’t know quite what to expect, or what to focus on, so I walked along with the group, recording observations of what looked interesting to me, some of which I had to key out at home.

The woods have been logged over recently, and show evidence of disturbance: a fair amount of non-native invasives, as well as Indian Tobacco (Lobelia inflata), about which the Flora of Virginia says, “In a wide variety of mesic to dry forests and woodlands, depression wetlands, flood-scoured shores and bars, clearings, fields, roadsides, and other disturbed habitats.”

There seemed to be some disagreement among the group about this Swamp White Oak (Quercus bicolor). I’m not sure why. Seems obvious to me.

Flipping rocks, the group found three Eastern Wormsnakes (Carphophis amoenus amoenus). White and White write, “This snake does not bite when handled but will try to escape by probing its head and tail into the captor’s hand searching for a way out,” which is just what this li’l fellow is doing in Ben’s hand.

At the lights, most of the group focused on moths and caddisflies. I’m just getting started with moths—I’ve never before seen moth eyeshine—so I spent more time getting to know some beetles on the groundcloth, like this handsome darkling beetle, Alobates sp.

Rea was giddy when she found this late-instar Regal Moth (Citheronia regalis). The larvae have the common name Hickory Horned Devil.

I took the opportunity to practice using my audio recorder. Need to work on setting levels and generally using it more before I splurge on field headphones and a shotgun mic.

Observations are still coming in.

NABA Butterfly Count 2022

mitigationBack to the area around the Clifton Institute for my first NABA Butterfly Count. We visited an extensive pollinator garden on private property (thanks to Shane’s Signs), a gravelled patch of Thoroughfare Road adjacent to a wetland mitigation project (photo), and a private horse farm. In the pollinator garden I made my first acquaintance of one of our hummingbird moth species (Hemaris thysbe) who were going gangbusters—not on our checklist, but still. I found the first of a few Sleepy Oranges (Abaeis nicippe) and Juniper Hairstreaks (Callophrys gryneus) that we tallied, and was finally able to twitch Peck’s Skipper (Polites peckius). Stephanie Mason pointed out this critter to me ages ago (“Peck’s have checks”) but that was before I started listing butterflies. But dang, skippers burn me out fast. We saw so many Sachems (Atalopedes campestris) in all their variability that the mental key began, “Is this skipper not a Sachem?”

No lie, it was hot. We started at 08:00 and I began to flag at 11:00. I am finding that a few hours of heat tends to make my feet swell in the waterproof light hikers that I usually wear. I was grateful for the jug of lemonade at the tally rally back at Clifton.

Clifton Institute dragonfly/damselfly count 2022

Dragonfy watchers at Leopold's Preserve by Marie Pinto (White House Farm Foundation)As usual, that’s me in the back, the last one to get on whatever we’re looking at. (Thanks to photographer Marie!) But well equipped.

No luck getting good images of the two common saddlebags species, but I did snap some reasonable images of Twelve-spotted Skimmer (Libellula pulchella) and what turned out to be Citrine Forktail (Ischnura hastata). Dang, those pond damsels are tricky. The best spot in our sector for pond damsels was again the pond behind The Farm Brewery at Broad Run. You know, the place with the axe-throwing barn.

Last Sunday was plenty hot, and we pooped out by 15:00 except for leader Larry. His pro tip for finding Wandering Glider (Pantala flavescens) is to check the parking lot: the critter has a tendency to mistake a car roof for a puddle.

Mixed blessings in this week’s report:

Wood Thrush singing in the parking lot, and was that a Little Blue Heron in the main wetland? Warm weather, some good results and some less so.

Boxes #6 and #67 finally hatched, having been overdue. Box #3 apparently only fledged one duckling. Boxes #1 and #77 have new Wood Duck eggs, having already fledged a clutch. On the not so good side, boxes #2 and #10 were abandoned, and we cleaned out those boxes.

So while we had clutches started in 15 of our 16 boxes, which is higher than usual, 4 were abandoned — also higher than usual. Plus the predation of box #13 by a Black Ratsnake (Pantherophis alleghaniensis). Perhaps it was the same animal that we saw at the box again on Sunday.

roof patchI put another patch on the knothole in the roof of box #67.

Down lower Barnyard Run, I found a big patch of Rattlesnakeweed (Hieracium venosum), and about four Fragile Forktails (Ischnura posita), a male and three females.

So we can shift over to spot-checking the remaining boxes with eggs (#77, #84, #1, #5, #61) on our next work day, on 29 May. I am on call for work that day, so I will have my phone charged up.

Thank you very much!

A much warmer and more successful morning.

More nests started, and five are incubating! Eight boxes are active. Our first Wood Duck box is #1, in the pool by the tower.

patchedWe repaired the hardware cloth on box #68. Access to #84 remains a problem: as mounted, the lid won’t open sufficiently. Next week we plan to repaint the number for box #67 and clean up trash around the tower.

Some splashes of Spring Beauty, with most buds tightly closed in the mid-morning.

Until next week! Arigatoo!

Small disaster. Last week’s cold snap and snow left the ponds iced over on Sunday. Ordinarily, we can break through the ice with our sticks, but the ice was just thick enough that instead, I tried following C’s footsteps out to box #2, the first box off the boardwalk— walking in an area that I didn’t know very well. Almost immediately, I lost my balance and caught some serious mud from the wetland. As a result, we cut the work day short. We’ll get ’em next week.

Another Sunday’s report:

Nests continue to develop. Box #68 added 7 eggs, just as if the hen was reading the calendar. My notes say that we have 4 eggs in #7 and 4 eggs in #77 — I will double check. And the 14 eggs in #6 are now incubating. It’s a little difficult to get a good count for this box.

We screwed together boxes #7 and #77. We also tried to adjust box #84, but in the process, the pole snapped off. It had rusted at the former waterline. So we did what we could, but the box is now low to the ground and a little wobbly.

K and C will leave some hardware cloth in the shed so that we can patch the duckling ladder in box #68.

I was responding to a query from a Friend of Little Hunting Creek: that group is looking to install some nest boxes, and I was sharing some of our experiences. And I realized that I didn’t have a previous blog post to direct them to on the subject of raccoon-resistant box closures. In fact, I couldn’t remember the name of one of the pieces of hardware that we use. So let’s rectify that missing information.

hook-and-eyeIn some cases, a hook-and-eye on a spring has been sufficient.

hasp and quick linkFor the more tenacious critters, we’ve gone to a hasp closed with a quick link. Links come in various sizes, so make sure you have one to fit the hasp. The link looks something like a carabiner, but it doesn’t squeeze open. Rather, you have to twist the hexagonal part. After a few years in the elements, you will need to give the link a bit of lubricating oil.

bookshelf November 2021The shelf was getting a little unbalanced, with too much fiction, but a tip from NPR’s Books We Love led me to Dreilinger. Of the Thoreau, I’ve got The Maine Woods and Cape Cod to read. The Bellotti is for a book club at work—not my usual cup of tea, but I want to contribute to the discussion. I have promised myself that I will crank through another story in the French parallel text collection; will I ever find time for the Echenoz? Juggling two volumes is too much trouble for the subway.

Suitland Bog

Lynn Rust’s Microbial Ecology class field-tripped to Suitland Bog (a magnolia bog that’s actually a fen). The property was once mined for sand and gravel before M-NCPPC picked up some of the land, while allowing development on another parcel. (In the inexorable logic of new streets being named for what they replaced, Rock Quarry Terrace passes through one of the nearby townhouse subdivisions.)

pine sandy 2pine sandy 1In the successional upland accessed by ample parking at the community center, we found the rocky, sandy soil of the Coastal Plain. Virginia Pine (Pinus virginia) is waiting to be overtaken by the beeches and oaks, while Blackjack Oak (Quercus marilandica) hunkers in the understory. Thundering helicopters from nearby Joint Base Andrews are just something you have to deal with.

In the bog itself, we easily found Purple Pitcher Plant (Sarracenia purpurea). According to Lynn and the park ranger, this introduced species is outcompeting the sundews, and is subject to some culls. Yellowing leaves of Sweetbay Magnolia (Magnolia virginiana) were recognizable.

Bisected by a power line cut, the place definitely shows the marks of human influence, and could use some major trash pickup love. I don’t remember, but I reckon that my visit in 2013 was from the other entrance, from the south.

Mason Neck State Park 2021

clutchingHoliday weekend, and a chance to earn my next badge in the state parks Trail Quest challenge. Somewhat unintentionally, I followed the same trails that I walked last year in late spring. Much quieter this time of year, cloudy-cool and a bit drizzly—glad I brought my hoodie.

minimastThe understory of the woods (holly-oak-beech) is very open; I suspect deer browse pressure. The oaks have dropped an abundance of acorns.

I found a little patch of Strawberry Bush (Euonymus americanus) (a/k/a Hearts-a-burstin’), still in fruit, on a hummock in a very wet spot. And an orbweaver making short work of an unfortunate Eastern Pondhawk.

The thing to remember about the Meadow View Trail, pleasant enough as it is, is that it is a trail to a view of a meadow. You won’t see any meadow along the trail itself.

3:00 for the circuit again, with a lunch break.

Neabsco Boardwalk

Barbara Saffir led a workshop at Neabsco Boardwalk on using iNaturalist and ISO axanthic Green Treefrogs (Hyla cinarea). And we found some!

new boardwalkThe boardwalk trail is rather new—nicely accessible and wide, open to multiple use (jogging, dogs, scooters). While the upland path to the boardwalk could serve for a nonnative invasives workshop, the wetland itself is pretty clean, a major exception being a population of Japanese Knotweed (Reynoutria japonica).
