In my spare time, I am starting to keep records of birds seen at the Winkler Botanical Preserve. This is between Shirley Hwy. (aka 395) and Beauregard St., just south of the Radisson Hotel at Mark Center in Alexandria, Va. It is accessible from Mark Center or Roanoke Ave. Between 9 & 10:45 this morning, I saw 20 species. The most interesting were 2 Black-throated Blue Warblers. First, I saw the female and had no idea who she was. Then, the male showed up and I had a positive identification. I like to think that they are a mated pair on the way to spend their winter in the West Indies. However, these days, who knows how long they have known each other? The only other warblers were the Northern Parula (near the "Hidden Pond") and a Common Yellowthroat male (near the large pond). A Kingfisher was also at the Hidden Pond and Hummingbird females were feeding around the large pond. Both Carolina and House Wrens were seen. If anyone else goes birding at Winkler, please post your observations on MDOsprey. A new nature center will be opening at Winkler and I hope to help by giving bird talks and walks. For more information about Winkler and its planned programs, call Jodie Smolik, the Executive Director, at 703-578-9109.
