A few days ago, when I was talking to the preserve manager Fred Gender, I complained that I have not seen very much in the way of waterfowl either in Brandywine or overhead. I had hoped to at least add a few species of ducks to my preserve list as migratory flyovers. I did add Cackling Goose and Green-winged Teal to the list, but that is it. I carefully check the Brandywine in both directions for mergansers or other ducks and check the skies overhead but almost always come up empty in terms of waterfowl.
Today when I started my walk, I looked downstream and saw nothing, then looked up stream and saw nothing. Then I stood and listened for what might be calling. Then I looked downstream again. This time I saw something swimming in the water just before the rapids. Finally! Common Mergansers, five of them, 4 males and a female, a new bird for my preserve list! I then turned and walked a short way to get a better view of the field to the north were several hundred Canada Geese were gathered.
As I was standing there Smaller groups of geese were flying in, mostly from the south. One group of five geese had two individuals that were notably smaller with short necks, making them Cackling Geese! Then two groups of about twenty Mallards flew past. The second group had a very dark bird amongst them. I got a pretty good look at it and could see that it had no white in the wings making it a Black Duck! Also a new bird for my preserve list!
I’m at the point now where new birds are becoming few and far between. To get two in one day just moments apart is pretty cool. I’m going with Black Duck as my bird of the day because it was totally unexpected. Later in my walk I near the south end of the preserve, I had a flock of 33 Snow Geese fly over, rounding out my waterfowl species count at 6. My previous high was four; Canada Goose, Snow Goose, Cackling Goose and Green-winged Teal on 25 October 2012.
