A Red-flanked Bluetail at Great Falls National Park

It showed up on eBird that a red-flanked bluetail was (and currently is) at Great Falls National Park in Virginia. The only other sighting of this bird in eastern North America was in New Jersey in winter of 2003. Being as this bird was only 16 miles from our house, it was an easy decision to chase this bird.

The red-flanked bluetail was once considered  a member of the thrush family (Turdidae), but is now considered to be an Old World flycatcher, (Muscicapidae). Regardless of the higher level taxonomic hi-jinx this is a very unusual bird for the area. However, it is a common bird and actually expanding its range into Europe – the likely source of this bird.

Anacostia Riverpup and I loaded up in the car and drove on out to Great Falls National Park. The nice person at the pay station was knowledgeable and told me where to park and look (almost kind of worth the $20 entrance fee). The park opens at 7 am and we were in the parking lot at 7:10 am. There was a large cohort of birders getting out of their cars and wrestling with winter clothes, binoculars, cameras, and spotting scopes. When throng of birders took off down the trail, Anacostia and I started to follow them, but she had some dog business to attend to. After I picked up her business transaction and walked back to the parking lot to dispose of it properly, we headed down the trail to where the pay station ranger suggested. Once at the ranger-disclosed spot, there was another birder (Nate) who gestured towards a tangle of vegetation. There was a bird there, but in the pre-sunrise light it was difficult to see much except for the subtly distinct bill shape – this was it. Nate let the throng of birders further down the trail know we were on the red-flanked bluetail. Instantly, all I could see was a blue coat. This guy was clearly tall enough to see over me, but some people on the east coast are just very me first. The blue coat guy jumped in front of me two more times. This bird was constantly in motion, had a preference for thick brush, seemed to always hide behind twigs & branches, and in general was difficult to get a good look at – but that doesn’t excuse boorish behavior. Anacostia was being a super good dog and I didn’t want to get in a fight with the blue coat guy, so we went for a hike and found some parasitic plants, cool lichens, and some liverworts.

As we were walking back to the car, I stopped to enjoy a mixed flock of the usual chickadees and such. As I was enjoying watching the mixed flock the red-flanked bluetail flew into the space. It didn’t join the flock, it just did its thing in the same space. It was pretty cool and I got good views. The throng of birders showed up pretty quickly, but it was mellow and I didn’t have people putting themselves in front of me.

Another human bit of interest was the bird was on the state line between Virginia and Maryland. For some birders it was important to see the bird from both states. This involved getting onto an island and seeing the bird on the island and from the island. I saw the bird in both states, but remained in Virginia.

After leaving that part of the park Anacostia and I walked around the Great Falls and Mathers Gorge. I am grateful that instead of a dump, industrial park, or sewage treatment plant this bird choose a really pretty spot. This was also a very cute little bird. This is a heavily used park, so the impact of 100’s of birders may or may not be noticeable to the environment. The bird seemed to not care about the mob of birders following it about. This was the first time I have chased a ‘rare’ bird (this bird is common, just out of place) and felt that the birding community has the potential to negatively effect the resource as many people were off trail which may impact the vegetation. I was also able to fill my pockets and backpack with wrappers, tissues, etc in the space the birders were occupying.

Everytime I have the opportunity to see a new bird species I learn something and this was an especially groovy bird to spend time with. There was just something about the way this cute little bird moved – it kind of reminded me of kinglets (another bird(s) I truly enjoy). An additional note, was how Nate, in contrast to the blue coat guy, spent quite a bit of time helping others to see the bird = this is the behavior that makes birding fun. I will try to be more like Nate!

Another DC Snowy Owl Chase.

When I moved to DC, I didn’t think snowy owls would be a bird I would see in town. Saturday I went out to chase my second DC snowy owl in six years of DC living, so I guess snowy owls are an occasional part of the DC birdscape.

The previous DC snowy owl hung out at Union Station, this one was reported on the banks of the Potomac River at the Reagan National Airport (DCA). This felt more like a snowy owl chase. Our weather has been cold and windy lately, and the bird would not have been visible without a spotting scope. Because DCA doesn’t let random folks wander about on the runways, the best view was from Hains Point looking across the Potomac River. This meant looking across a km over open water.

When I showed up at the crack of noon there was nobody at the prime viewing spot, so I set up my scope and started viewing all the white plastic trash washed up on the banks of the Potomac River. I saw no owl, so I did what any good birder does and repeated my scan. Two birders showed up on their bicycles (the best way to get around in DC). We shared my scope and found the snowy owl hunkered down in a driftwood pile on the DCA boat ramp. It looked very similar to a lot of the plastic trash until a bit of preening showed it to be a snowy owl. The bicycle birders were new birders and after basking in the success of finding the target bird we put the scope on a flock of buffleheads in the middle of the river and they got a second lifer. As I was about to leave a couple more birders showed up and we helped them get their scope on the bird.

I have kayaked near DCA and it is amazingly loud. It would appear that the snowy owl was not bothered by the jets taking off and landing, but that would be best determined by examining corticosterone levels in the blood.

I have heard of snowy owls using airports to winter and have seen snowy owls using beaches/shorelines before, so this isn’t unheard of. I am continually surprised at the birds that show up in DC.

The big ol’ sycamore leaf of destiny.

The big ol’ sycamore leaf of destiny.

Every fall, I always spend some time amazed at how big sycamore (Platanus occidentalis) leaves are. So on November 1st while hiking a kayak to a beaver pond at Watkins Regional Park (MD) I was delighted to find an absurdly large sycamore leaf on the ground along the trail.

This leaf is 50 cm wide and 32 cm tall – big enough to have its own area code. It is always cool to find superlative specimens and the only way to do that is to go outside, have fun, and pay attention. However, even if what you are finding isn’t  the biggest, fastest, or otherwise bestest – it is still part of ‘team Earth’ and that is pretty groovy in and of itself.

Paddle trip report: the Beaver Pond, Watkins Regional Park, MD.

This is another installment in the places most folks do not paddle series.

While ‘day-camped’ at Watkins Regional Park, I took the opportunity to try and paddle the Beaver Pond in the park. I loaded my kayak, pump, and paddle into a backpack and proceeded to hike to the pond.

It was a beautiful fall day and the hike took me through woods, on a bike path along a park road, and through a soybean field. The hike to the Beaver Pond was a very pleasant 2.5 km – which is good because when you are accessing places to paddle based upon maps you may just be hiking. The first views of the Beaver Pond showed that the maps were correct, this is a spot worth paddling.

The trail led right to the pond and even had a convenient bench right in a nice clear spot that was perfect for inflating the kayak. The put-in required a carry over a downed log, but it was pretty straightforward.

Once on the water there was quite a bit of brushy shrubs (Cephalanthus, Salix, and Hibiscus) to maneuver around and through, which demonstrates that the water isn’t very deep. I was surprised to find a little island in the middle of the pond. It was easy to find the beaver lodge and pay my respects to my hosts. The presence of ~3 dozen Canada geese was pretty cool. I also had nice views of a piliated woodpecker and red-shouldered hawk.

This was a really nice paddle. A circumnavigation of the pond is about a 1 km paddle. However, paddling smaller waterbodies obviously isn’t about paddle distance. It is about exploration, enlightenment, and enjoyment. I had a perfect paddle and a really nice hike on a splendid fall day.

Parasitc plants: Epifagus virginiana

Image
Fagus grandifolia, the American beech. Patuxent River, MD. 20 September 2025.

Fagus grandifolia (the American beech) is a tree that makes me happy. It is in the same family (Fagaceae) as oaks and chestnuts. Beech trees can be magnificent, towering, smooth-barked forest specimens when mature, but often it seems they have hollow trunks, gnarled limbs and roots – which is even cooler. Unlike the oaks, beech trees seem to require shady, moist forests and only reach the canopy when mature. These forests can be challenging places for non-canopy vegetation because there isn’t a lot sunlight. Some plants, like Tipularia discolor will do all their photosynthesis while the canopy trees do not have leaves. Epifagus virginiana has a different strategy for dark, forest floor living: no photosynthesis at all.

There are two ways a plant can live without doing photosynthesis: either by engaging fungi and assuming a saprophytic lifestyle (example: Monotropa uniflora) or by tapping into the roots of plants and assuming a parasitic lifestyle. A plant that does no photosynthesis and receives it nutrition from other plants is said to be holoparasitic. In the case of Epifagus virginiana beech trees provide the nutrition. The presence of beech trees is also required for seed germination. The seedlings develop under ground sending roots to form haustoria with the beech roots and via the haustoria the seedling receives nutrition from the beech tree.

It is pretty common to see the dried up, dead stems of Epifagus virginiana when enjoying beech trees all year, as this is not a rare plant. Recently, Kelly and I were camped along the Patuxent River and we found fresh Epifagus virginiana stems about to flower. As an annual plant, flowering and seed production are very important activities.

Epifagus virginiana is in the plant family Orobanchaceae which is mainly comprised of hemiparasitic (photosynthetic) and holoparasitic (non-photsynthetic) members in several genera. We tend to view parasites as nasty things (anybody want a tapeworm?), but this may not always be the case. Epifagus virginiana is a common (parasitic) companion of Fagus grandifolia, and doesn’t seem to be causing mortality of the host tree. It would be interesting to know if Epifagus virginiana has any impact on lifetime seed set or other life history parameters of Fagus grandifolia. But, until I win the research funding lottery, this will have to be a mystery.

One thing I do know is that the natural world is often more complex and connected than we imagine. As John Muir said: “When we try to pick out anything by itself, we find it hitched to everything else in the Universe”.

Belted Kingfisher vs. Coopers Hawks

River view. NE Branch of the Anacostia River. 22 September 2025.

While up the NE Branch of the Anacostia River to get a semi tire we had previously noticed, we were treated to a true-life nature spectacle of two Cooper’s hawks hunting a belted kingfisher.

Cooper’s hawks are specialized for hunting birds and can outfly most birds. I have seen Cooper’s hawks intercept prey species in flight in open air, dense woods, and thick shrubs. I have even seen Cooper’s hawks walk into really thick vegetation to take prey. To put it bluntly, I am very glad that they aren’t larger, because they are bad ass predators that would make the Jurrasic Park Velociraptor look like a minor inconvenience.

Belted kingfishers are fish-eating birds that can hover, plunge dive into the water, and then takeoff from the water. While I don’t think of kingfishers as strong flyers, they are very capable in the air.

The sighting started with two Cooper’s hawks flying downstream. Both birds were first year and similar in size (female). When a Belted Kingfisher left its streamside perch in front of the pair of Cooper’s hawks, it instantly had the attention of both of the hawks and I. One of the pair swung high and dove on the kingfisher, but the hawk missed and narrowly avoided getting caught in the river (I don’t think a Cooper’s hawks can take off from water). The hawks swung around and made another failed pass at the kingfisher. The kingfisher not only was outflying the Cooper’s hawks, but it almost seemed it was taunting them with its laughing, rattling, call. After another attempt at the kingfisher the hawks continued downstream where some easier prey must certainly exist.

I would not have expected a kingfisher to survive one Cooper’s hawk, let alone two. It may have been a different story if a seasoned adult was going after the kingfisher. It was pretty exciting being able to watch all this drama from a kayak.

Breaking Anacostia River Dragonfly News!

Hagenius brevistylus. Little Beaver State Park, WV. 14 June 2025.

On 22 September 2025 Anacostia Riverpup and I were returning from a trashyaking excursion up the NE Branch of the Anacostia River. We were upstream of the Bladensburg Road bridge when I saw a large gomphid flying across the river and landing close to us on a sycamore sapling: Hagenius brevistylus, the Dragonhunter! Being as we already had a semi-tire and other trash on board the kayak, I wasn’t able to sneak up and get a photo of this occurrence.

I keep coming back to Orr’s 2001 paper in which he declares that with regard to Odonata, the Anacostia River is dead. At the time, no doubt he was correct. Twenty-five years later the Anacostia River has improved enough that not only does it support dragonflies, it also supports dragonflies that hunt other dragonflies.

The Anacostia River has come so far, but still has a long way to go to be called restored.
