We have lots of red salvia in our back yard, and it attracts hummingbirds.  While I was sitting on the patio reading a book, a hummingbird spent almost two minutes darting its beak into individual pods on the salvia bloom.  I wished I had my camera with me to take a picture of the quick-moving tiny bird, but I knew if I moved, the bird would fly away.  I just enjoyed the moment and watched it work.
