And several trips to my home park, Huntley Meadows Park.
A 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).
Ryley 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).
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.
On 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.
On 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.
Dave 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.
In 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.
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.
Mostly 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.
We bounced back from the dismal 2015.
From my final report to the team:
It seems like every year I get this final report put together later and later. At any rate, this was a much more successful nesting year for our Wood Ducks and Hooded Mergansers.
Of our 16 boxes that we monitored, we had 16 nests started. That is, one box had a double brood and only one box this year was not used. Of the 16 nests, 13 were (predominantly) Wood Duck, and three Hooded Merganser. (We often have some eggs from the other species in the nest, which messes up the recordkeeping that I submit to the Cornell Lab.) And of the 16, 13 fledged at least some young, one failed, and two I’m just not sure about. The two questionable boxes are #1 and #3, near the tower. When we checked on 8 May, the evidence indicated predation, but when we visited on 22 May, I saw evidence of membranes, indicating that some eggs had hatched.
So, not counting the two questionable boxes, we have a fledge-to-eggs rate of 70% (114/163) for the Woodies and 91% (31/34) for the Hoodies….
Thanks again, everyone, for the hard work, and we’ll see you in February/March! When it should be colder.
Stephanie Mason led members of her posse on a summer walk in the Blue Mountain area of G. Richard Thompson WMA. This patch is well-known in spring for its ephemerals, trilliums, and orchids, but there’s plenty to see once the trees have leafed out, too. The weather was cool for July, generally overcast, with a bit of a shower towards the end of the day. Not much happening on the butterfly charts.
The bird checklist for the trip was short, but we had some goodies. Heard and seen Common Raven (Corvus corax), Red-eyed Vireo (Vireo olivaceus), and Acadian Flycatcher (Empidonax virescens). And brief glimpses of Kentucky Warbler (Oporornis formusus) and Cerulean Warbler (Dendroica cerulea).
But the theme of this walk turned out to be beetles. Perhaps the cool temps slowed these crawlies down so that we could get good looks. At left, trying to convince you he’s a Milkweed Bug or firefly is a net-winged beetle (Calopteron sp.). We have three species here in the mid-Atlantic. Distinguishing them calls for looking at features like antennomere colors—beyond the quality scope of my image. At right, creeping over my knuckles and trying to stay out of focus, a Larger Elm Leaf Beetle (Moncesta coryli); according to Evans, this is the largest leaf beetle species in North America.
Kit Sheffield led a ferns workshop last Sunday (yes, it’s been a busy week). We looked at a lot of ferns, some plants that don’t look like ferns but are, and of course some plants that aren’t ferns. We started at the Visitor Center, followed the river trail as far as Gladys Island and Carper’s Pond, then looped back via the Nature Center.
Some new ferns for me were Lowland Fragile Fern (Cystopteris protrusa) (left) and Broad Beech Fern (Phegopteris hexagonopera) (very handsome).
A few fern ID tips:
- The first thing to look for is growth pattern: does this fern grow in a clump, or singly?
- Look at the bottom pair of leaflets, for instance to distinguish Lady Fern from Hay-scented Fern. This is also useful for applying my “opposite Onoclea” rule.
- Look for hairs in the axils (armpits) of Cinnamon Fern.
Something that didn’t look like a fern for centuries, but is now considered to be one, based on fossil evidence: Scouringrush (Equisetum hyemale). Unfortunately for the quality of the image, the growth tips of this specimen have been deer-browsed.
One more fern, Rock Polypody (Polypodium virginianum). Cute name, cute fern!
And a not-a-fern: Ramps (Allium tricoccum) are in flower.
One more report from the nest box monitoring team for the season:
This year is turning out to be quite successful. Two more Wood Duck boxes have hatched out (box #61 at left), bringing the total to 8 successful WODU nests and 3 HOME nests. This is not counting boxes #1 and #3, which may have been predated, even though a second look turned up some egg membranes. We did see 3 young mergansers in the vicinity of these boxes.
We have at least two boxes still incubating (#6 and #77). #6 will be a second clutch for that box. #68, down at the end in the cattails, has 6 eggs, but it is perhaps a drop nest — we have not been checking it regularly.
We’re done with all-hands work days for the season. Kat and Chris, if you could check #6 and #77 in a couple of weeks, that would be good; I will spot-check #68 probably in two weeks on 19 June, or I will check it a week after that.
Paul, was is Wood Duck eggs that you saw in #68?
A Wild Turkey crossed the entrance drive as I arrived this morning. Paul spotted a Red-headed Woodpecker, down along the reach of Barnyard Run that they are partial to. Many tiny toadlets were crossing the trail as we walked out to the wetland.
Thank you all! I will post a wrap-up message, probably some time in July.
Our boxes support life of all kinds. This the the top of box #67, showing examples of three lichen growth forms: crustose (clinging to the substrate), foliose (peeling up like a leaf), and fruticose (bushy, like Reindeer Lichen).
There is a little patch of one of our hawkweeds, Rattlesnake Weed (Hieracium venosum) centered on a tree along the Cedar Trail, right before it divides to make a loop. I’ve keyed this flower out before, but this time around I was able to get some passable images. The purple-veined leaves of the basal rosette are the ID clincher.
Our final field trip with Rachel Gauza’s class took us to the Bethesda-Chevy Chase chapter of the Izaak Walton League of America, 600-odd acres near Poolesville and McKee-Beshers WMA. Out host was Larry Anderson. Our targets were snakes, but we didn’t score well with that taxon. However, we found plenty to look at off the West Woods trail. Please don’t mind the nearby gun range.
As you might imagine, deer management is an advanced art here, so it’s not uncommon to see nicely developed understory vegetation. Although we did see patches of the usual non-native invasives, we also saw some good natives—lots of Pawpaw (Asmina triloba), some Smilacina, a chance encounter with a bellwort, not yet in flower, Chestnut Oak (Quercus montana) on the ridgetops; Cathy spotted Wild Ginger (Asarum canadense).
And we did see some herps! Pickerel Frog (Lithobates palustris), too hoppy for my camera, and multiple Marbled Salamanders (Ambystoma opacum). Rachel says that this is the first time that she’s seen Marbleds on the property.
The latest from our nest box monitoring:
A quiet, drizzly Sunday morning, but a sufficiency of activity to report. Upstream, Kat and Chris report hatches in boxes #4 and #7; and at the other end, box #67 hatched as well. We have a second clutch going in box #6, by the big pool, as well as clutches going in boxes #77, #5, and #61. When I opened #61, the Wood Duck flushed and executed a fine broken-wing distraction display.
Of our 16 boxes, we have had nesting activity in 14 of them….
Let’s do this again in two weeks on 5 June and check all boxes, and then one more time on 19 June to spot-check the stragglers.
From our most recent nest box monitoring report, with some photo annotations:
Win some, lose some: Box #84 is hatched out, and Kat and Chris found WODU ducklings in box #2. It’s possible that a Wood Duck is starting a second clutch in box #6, with 2 eggs laid there recently. So for the season, that’s 13 of the 16 boxes with nests, and 6 nests that have fledged so far.
On the downside, it appears that boxes #1 and #3 were predated by snakes: the boxes are not messy inside, just empty, and there is mud streaking in box #1’s pole that could be snake-caused. These are the 2 new boxes bear the observation tower, the ones that don’t have predator cones.
Let’s meet again on 22 May and check all the boxes. Based on what we find then, we’ll make a plan for at least one day in June, perhaps two.
We got some looks at the Barred Owl adult and owlets; newly-observed birds for the season were Acadian Flycatcher and Northern Rough-winged Swallow; migrant Pectoral Sandpiper and other shorebirds. Chris turned up a wee American Toad near the vistors’ center.
From my most recent report on nesting activity:
12 of 16 boxes with nests, and one more with adults seen in the vicinity! As of 1 May, boxes #10 (Hooded Merganser), #6, #13, and #62 (Wood Duck) have hatched out, more or less in the usual proportions.
Birds noted on 10 April: Glossy Ibis, Eastern Phoebe, Eastern Kingbird. Birds noted on 24 April: Common Yellowthroat, Eastern Towhee, Red-eyed Vireo, Lesser Yellowlegs, Chimney Swift, Barn Swallow, Green Heron. On 24 April, Houstonia sp. was in bloom near the end of the berm. There is a Tree Swallow nest in the broken top of a maple, down along Barnyard Run, near the “helper log” that lies across the channel near box #61.
We’ll meet again this Sunday, 8 May. Let’s skip checking box #7.
Our first field trip for Rachel Gauza’s herps class took us to Jug Bay Wetlands Sanctuary in Anne Arundel County. Our host guides were Mel Fegler and Mike Quinlan. This is a popular natural place on the Coastal Plain, and rightly so. I heard my first Wood Thrushes of the year in the parking lot.
But the focus today is amphibians and reptiles! In the morning, we worked several spots near the McCann Wetlands Center. Mike found an Eastern Wormsnake (Carphopis amoenus) under a coverboard in the meadow adjacent to the center.
Moving into the deciduous woods along the Middle and Forest Trails, we saw a nice selection of herp diversity: Eastern Box Turtle (Terrapene carolina), Wood Frog (Lithobates sylvaticus), American Toad (Anaxyrus americanus), Fowler’s Toad (A. fowleri), Marbled Salamander (Ambystoma opacum)—and one toad of doubtful status that I want to follow up with Rachel on.
We dropped down from the right of way of the railroad that once ran from Seat Pleasant to Chesapeake Beach into the floodplain of Two Run Branch to visit several seasonal (now dried) and persistent pools. Opportunities to see Marbled Salamander larvae, Eastern Cricket Frog (Acris crepitans), and a choice-sized American Bullfrog (Lithobates catesbeianus). Marbleds breed in the fall and the eggs overwinter, giving them a head start in develop come spring, so (as you can see), they’re already well along the way to becoming adults.
At lunch break, back at the center, I heard a Summer Tanager (Piranga rubra), and I think this is the first time that I’ve heard the call that Dick Walton’s tapes taught me so long ago as “piki-tucki-tuck.”
In the afternoon, Mel took us to a seasonal pool on the the Glendening Nature Preserve section of the sanctuary, the pool known locally as Barn Pool. We did some sweep netting through this pool, in a very rough approximation of the sampling protocol that Mel follows when she’s monitoring. The water levels were quite reduced, but there were many Marbled Salamander larvae to be netted.
