Blockhouse Point Conservation Park

dying backOn a drizzly Sunday morning, Carole Bergmann led a walk through Blockhouse Point Conservation Park. Fall colors were quite good, the Pawpaws getting ready to drop their leaves. This Sensitive Fern is packing it in for the season.

cespitosebeardyFellow walker Tom was our fungi maven. At left, he ID’d this cespitose cluster of stipes as Pholiota squarrosoides. And for a second non-polypore fruiting from the trunk of a tree, he also called Hericium erinaceus, at right.

VNPS 2017: Ice Mountain Preserve

quiet nowKevin Dodge, Shirley Gay, and Steve Kite led a walk though Ice Mountain Preserve. The northwest face of the ridge is an immense talus slope, as the North River gradually eats away at the base of the mountain.

it's cool insideThe pores between the boulders are a magnet for cold air. The air vents out at the bottom of the slope. In winter and spring, these vents are covered with ice.

at least oneThe trapped and released cold air provides growing conditions that are closer to boreal than mid-Atlantic. Most of the veg we saw was mostly gone by, but one Bunchberry (Cornus canadensis) was still holding on.

Closer to the trailhead, we found a few examples of Cut-leaved Grape Fern (Botrychium dissectum).

Turkey Run Ridge

For Labor Day, a 5-mile loop in 3:50 through Prince William Forest Park. More or less tracking the hike in PATC’s Hikes in the Washington Region, Part B. My edition is from 1993, so some crossings have been rerouted since then.

The only butterflies about were some Red-spotted Purples in the parking lot. Big patches of running cedar; the trails still somewhat wet after Saturday’s rains. Definitely folks on the trail, but not what you could call crowded: one large group of hikers, but mostly couple and trios. Lots of (generally leashed, well-behaved) dogs.

The High Meadows Trail (simply trail T-10 in the PATC guide) is a misnomer, as it traverses very beechy-hickory woods. Laurel hells along the South Fork of Quantico Creek. A muggy day, if not that warm: wind in the treetops, but rarely for me.

Many of the streams with heavily scoured banks, evidence of the hard use this land had been put to.

coralSome interesting mushrooms, again many of them popped from recent rains. The best match in my field guide for this is Ramaria aurea.

not yet ripeI stopped for lunch at a small stream crossing. As I munched, I found a single Indian Cucumber Root (Medeola virginiana) in fruit, if not yet ripe. I’d never seen the red creeping into the base of the upper leaves before.

New York Botanical Garden

what's the buzztiny whitesA few snaps from my trip to the New York Botanical Garden on a very warm, generally sunny day. The place is huge! I budgeted a good chunk of time in the Native Plant Garden, site of the memorial to Elizabeth Gertrude Knight Britton. A couple of less common plants in flower were a mountain mint, Pycnathemum curvipes (left) (hmm, USDA PLANTS says that this not native to New York, but only to North Carolina and south) and Flowering Spurge (Euphorbia corollata) (right). Newcomb points out that the delicate white flower parts on the spurge are actually bracts, not petals.

cascadeIn the nearby Rock Garden, this engineered cascade is quite lovely.

citizen scienceIn the less-tended bits of the grounds is the Thain Family Forest. An interpretive sign calls out the importance of citizen science, and just a few steps down the trail is a Picture Post.

cycad selfieAfter lunch break, I spent most of my time in the conservatory. I do love me some cycads.

Sky Meadows double loop

On my way out to visit Charlie, I took a fairly easy double-loop hike in Sky Meadows State Park. I didn’t push very hard on the climb, taking the shortcut across on the Gap Run Trail, which proved to be very good for singing Wood Thrush. Acadian Flycatchers, a pair of Scarlet Tanagers, and several Indigo Buntings also were heard and seen.

The mostly sunny, sweaty summer day was also pretty good for butterflies, in particular a Zebra Swallowtail or two hanging out around its larval host plant, Common Pawpaw.

not quite sureI followed the Snowden loop (I think this trail is new to me): some gentle climbing as the loop reaches the southern edge of the park property. This trail was much less busy than the ridge trails. At the second stream crossing (not much more than a trickle), I pulled out my camera to photograph an interesting orange and black guy (he didn’t stick around), but I did get a snap of what I’m pretty sure is a Tawny Emperor (Asterocampa clyton).

Best bird of the day was a Brown Thrasher checking out a ripening patch of (alas, abundant) Wineberry.

All told, about 3 miles in 3:00.

Wood Duck and Hooded Merganser trend chart



From my summary report to the team:

As for predation by the snakes, I wouldn’t move any of the boxes just on the evidence of this season. Last year it was boxes #1 and #3 where we had a problem; this year it was #7 and #62.

no TyphaLocal conditions around box #69 have changed. Past years, it was overrun with Typha sp. by mid-May. This year, it remained clear of veg.

As for nest structures for Mallard and American Black Duck, let us know where you’ve placed them and we will try to work them into our monitoring routine. My references show that the nesting season for these birds extends later into the summer, so we would have the opportunity to extend our work season.

A pattern that I’ve noticed over the years is that the fledge-to-eggs ratio for Hooded Merganser is usually higher than that for Wood Duck. A couple of hypotheses:

(1) Since the mergs start laying eggs a little earlier than the woodies, perhaps they out-compete them and occupy the more favorable boxes for that year. (We don’t see that one species is particularly faithful to a box, and indeed since we see a few mixed clutches, a box may be considered favorable by both species.)

(2) We are more likely to see “dump” and “drop” nests for the woodies: boxes with 20+ eggs. And with these jumbo clutch sizes, it’s more difficult to incubate all the eggs sufficiently.

Sugarloaf loop

Too long away from the park, I set aside today for an easy 5-mile loop using the AT, Sugarloaf Trail, Pole Bridge Link Trail, and Keyser Run Fire Road.

Top bird sighting for the walk was a couple of female American Redstarts (Setophaga ruticilla).

pinkThe Sugarloaf Trail has a big swath of Mountain Laurel (Kalmia latifolia) just coming into bloom. Less easy to ID to species were several patches of pinxter azalea—given the conflicting keys in the Flora of Virginia and Newcomb, I’m going to call this just Rhododendron sp.

tiny, tiny flowersI had more success keying out a saxifrage that was having a great time in the stream of Keyser Run, and this Wild Yam (Dioscorea villosa), a plant that I’ve seen before, but perhaps never before in (tiny, tiny) flower.

crossinghanging onAlong the multiple streams of Piney River, I found one of my favorites, Golden Ragwort (Packera aurea)—a little past its prime.

as close as I cared to beThis guy? I gave him his space.

Making the climb up Hogback Mountain, I found a very hungry Microtus vole, who hung around long enough for some views, but no good photographs.

I covered the 5-mile loop in a very leisurely 4:35. According to my notes, I made this same hike in February 2008 in 2:30. There’s less to see and hear in February; I took a long time waiting for those butterflies; and I carried a few more cookies up Hogback Mountain than I did nine years ago.

slightly wornBest invertebrate of the walk was Mourning Cloak (Nymphalis antiopa), found in a small group on the AT near the parking lot. This individual, albeit a bit banged up, gave me a reasonable look.

A report from the 14th:

Greetings, duck boxers! The 14th saw hatching evidence in 5 more boxes, bringing the season total to 7 boxes with hatched eggs. Unfortunately, it appears that box #62 was predated, at least in part; Paul evicted a Black Rat Snake from the box.

In box #10, eggs were in the process of hatching; the female Wood Duck attempted to entice us away from the box with a broken wing distraction display.

the view from box #13With the holiday and such, the 4th of June makes more sense for our next work day. We will need to check only 6 remaining boxes, so the morning should go quickly. Among these are #10 and #13, which might possibly have a second clutch started.

Bird of the day was Acadian Flycatcher, heard quite distinctly in the woods on the way to the boardwalk.

From my last report to the nest box team:

Much activity in the boxes so far this year! We’ve had nests in 14 of the 16 boxes. Of these, box #2 has already hatched out (unfortunately, only 8 of 22 eggs hatched). Also, oddly and sadly, box #6 hatched just one Hooded Merganser egg while the 13-15 Wood Duck eggs did not hatch. Kat reported the sounds of pipping in box #1.

So we should have several more boxes hatched out for our next session, on 14 May. For 28 May, I think that we will just spot check known active nests. Depending on what we find then, we can make a call on when and what to do in June.

Bonus birds from last Sunday were Prothonotary Warbler (heard, and seen by some) and Red-eyed Vireo (heard, perhaps seen).

Great Backyard Bird Count 2017

I got started earlier in the day, and somewhat surprisingly, the list is shorter: only 17 species this year. Good weather (forties) for birding. Got the pair of RSHAs.

mid-autumn colorA lazy midday stroll to the tower and back through the woods. Despite the season, a rather birdy day, perhaps due to the crazy warm temperatures. A Bald Eagle (Haliaeetus leucocephalus) cruised by. Most notably, I watched an altercation between a Red-bellied Woodpecker (Melanerpes carolinus) and a juvenile Red-headed Woodpecker (M. erythrocephalus).

today's mysteryToday’s mystery flowering plant is this lance-leaved low shrub (about 2 ft.), with slight wings along the stem, growing near the boardwalk and nearly in the water.

VNPS 2016: Wildwood Park

very wet meadowsharpRyley Harris led last Sunday’s walk through Wildwood Park in the City of Radford. The park lies on both sides of Connelly’s Run, as it flows roughly north to the New River; the stream lies at the bottom of an abrupt gorge that once separated the two halves of the city. Seeps and other flows provide wet meadow conditions along the hike-bike trail. At left you can see Impatiens capensis (I. pallida is also found here), a Solidago, an ironweed (Vernonia), Queen-Anne’s Lace (Daucus carota), and Cowbane (Oxypolis rigidior) (and in closeup). Also along this path were the remnants of the preposterously-leaved, square-stemmed Cup Plant(Silphium perfoliatum).

lushlush, tooOn the far slope of the gorge, it was another day for looking at lush, leafy green ground cover: Wild Ginger (Asarum canadense) (left) and Sharp-lobed Hepatica (Hepatica acutiloba) (right).

mystery lepThis mystery caterpillar (maybe an Banded Sphinx Moth (Eumorpha fasciatus): the book says that they show a lot of color variation as they prepare to pupate) also made an appearance.

VNPS 2016: Mountain Lake

A busy-busy week (build manager at work, video production class in the evening), so I am just now writing up two successful field trips that were part of Virginia Native Plant Society’s annual get-together. Home base was Blacksburg, and this year’s meeting was hosted by the New River Chapter.

My first surprise, once I arrived and took a look at the geophysical and hydrology maps, is that this part of Virginia, such a long schlep down I-81, is not part of the system that drains to the Atlantic Ocean. Rather, the New River drains north and west to the Ohio, and thence to the Gulf of Mexico. However, it is part of the same Ridge and Valley Province (do you say Valley and Ridge?) as the more nearby Massanutten Mountain and Sideling Hill.

shrubbyOn Saturday, Dave Darnell led a walk on the War Spur Trail in the vicinity of Mountain Lake in Giles County. Much of the lands here are part of the George Washington and Jefferson National Forests. Mountain Lake is one of only two natural lakes in the commonwealth; unfortunately, drainage conditions lately have left it rather dry. The trailhead was at about 3700 feet. On the mountain, immature sprouts of American Chestnuts (Castanea dentata) are easy to find, their reproductive fates unfortunately sealed by the pathogen Cryphonectria parasitica. This is an acidic, rocky soil; the plant community is probably best described as High-elevation Red Oak Forest in Timothy Spira’s system.

somewhat shinyOn the ground, the evergreen leaves of Galax urceolata are easy to spot. Also abundant were the non-photosynthesizing plants with a complicated lifestyle: Bear Corn (Conopholis americana), Pinesap (Monotropa hypopithys), and Indian Pipe (M. uniflora). In the darker patches, individuals of Eastern Hemlock (Tsuga canadensis) are undaunted.

thanks for the drinkDave pointed out a bit of Lung Lichen (Lobaria pulmonaria); the photo shows the lichen after it was doused with my water bottle and sprang from shriveled, dusty brown to fresh green. Lung lichen is does not tolerate air pollution well, so this is a good species to see.

boggy landscapeIn the afternoon, Dave took us back down the road to the University of Virginia’s Mountain Lake Biological Station, a residential research and teaching space for undergrads and graduates. At the edge of this property is a rather extensive spahgnum/spruce bog, where some really big Red Spruce (Picea rubens) can be found, along with thickets of Rhododendron maximum the size of a house.

Rose River loop

For a birthday walk Leta and I took a very leisurely loop hike along the Rose River and Hogcamp Branch. We also dallied before starting out, so the Fishers Gap parking area was packed and the trail was full of families, couples, dogs, and suchlike.

turningMostly White Wood Aster in bloom, along with various Helianthus and a smattering of phlox. We heard one Common Raven along Skyline Drive. Unexpected mammal sighting was a pair of young Black Bears near the bottom of the Hogcamp Branch section of the trail; we kept our distance.

rocks are for sittingFor this 3.7 mile circuit we took 4:00. No huffing, no puffing, just some practice with the new camera, good company, and a nice walk along the water.
