I spotted this beautiful warbler moving very rapidly through the understory of the woods on a college campus. A few days later, I saw another one in nearly the same spot. In the next eleven years, I saw an additional total of one. If I had known how rare it would be for me, I would have made an effort to follow it for a while. But there were other warblers in the area, and I turned my attention to them.
