Following this bird with my camera was an "In focus!
snap, In focus!
snap" ordeal. Later, when I got a good chance to review the photos I came across this one. I was, at first, amazed that the bird was content with being upside down while searching for food. And then it dawned on me that it was light enough to hang by a single pine needle.
