My visit to Central Park started with the search for the Western Flycatcher. It was the star of the day. A vagrant from the west coast, it is unclear if it is a Pacific-Slope or Cordilleran Flycatcher. It was photographed by at least twenty photographers, so I decided just to watch it. A fun bird to watch and get to know, even if it looks a bit scruffy. The two species interbreed, so the discussion about "which species this is?", is really fascinating. See the NY State Bird List for an interesting discussion.
The end of the day was with the Great Horned Owl which was cooperative before and after fly out. It tends to like the tops of bare trees after fly out, which helps greatly while following it after fly out.
