This month’s candidates included three different birding adventures, all of which required a trip to central Pennsylvania. After careful consideration, looking for migrating tundra swans at Middle Creek Wildlife Management Area seemed like the most likely to pay off, and also a good choice to mark off a handful of new birds on both my year and life lists. Since other migratory waterfowl were likely to be found in the same area, this seemed like a two-for-one deal, as well.
For a number of reasons, this one was a Ben solo adventure (the lower-case ‘s’ here is key). I missed my normal companions but there is also something great about being alone in nature. Somehow it makes one feel more connected to the wildlife one is observing, and more capable of appreciating the beauty of the environment for its own sake. That said, there were a number of other birders at and around the refuge that day, and one in particular who was very excited to show me what he’d found with his scope. I had picked out most of what he had to show me, but I have to admit the view through the scope was superior.
Tundra swans (Cygnus columbianus) are remarkably similar to trumpeter swans but smaller and with subtle differences in the bill and neck. Middle Creek has become an important stopover for them in their Spring migration back to their breeding grounds on – big surprise, here – the tundra. What may be actually surprising is that many of the birds who winter along the Atlantic coast breed in eastern Alaska, adding a huge East-West component to their migratory pattern. That’s just not something my brain is wired to consider as part of the picture, given the ceaseless repetition of the phrase “fly south for the winter.”
The photo above can give you a good idea of the number of swans present last Saturday. This was taken from atop the Millstone Trail looking North across the lake. In the middle distance, along the north bank, each of those white dots is a swan. The second group of airborne white dots farther in the distance is a medium-sized flock of snow geese. I arrived a bit late to see the peak migration; thanks to our early spring this happened in late February this year. At that time the snow geese numbered around 70,000 and the tundra swans about 2,500 birds. By the time I visited the numbers had dropped to a still-impressive few thousand geese and few hundred swans. For those interested in catching the full spectacle in future years, you can check the WMA’s official migration update page.
I mentioned this was also a great opportunity to see other migrating waterfowl (another March activity in the book I’m following) and this too was a wild success. In addition to the ducks and geese, I got good looks at dozens of American coots, about 30 common mergansers and 20 green-winged teals, a half-dozen elegant northern pintails, plus a handful of American black ducks, gadwalls, ring-necked ducks, and American wigeons. I guess I’ve skipped over the Canada geese, but there were plenty of those too. I also caught a glimpse of a golden eagle that has been a continuing rarity, and watched some American tree sparrows (new to my life list) for a bit. Side note: we really like to name birds “American” whatever, don’t we? On this day I also saw the less noteworthy American crow, American robin, and American goldfinch.
There was more to appreciate than birds. It was still a wintry scene, but in the wooded areas was a gorgeous carpet of princess pine. There were quite a few stands of evergreens amid a light layer of snow, and in some of the low-lying wet areas near the lake shore were pockets of skunk cabbage. Finally, the water of the lake itself created some beautiful attractions. As small waves washed over low-hanging tree branches and roots in the twenty-degree air, lovely patterns of icicles formed. I admit that at two-and-a-quarter hours each way from Silver Spring, this is a bit of a hike for a day trip, but I found the experience well worth the effort.
