Here are some recent shots of the anna's hummingbird.
Shot with the 7D and 400mm f/5.6.
The hummingbird shots were taken with my camera on a tripod and triggered remotely. I had the camera pre-focused on the flower. If I was out to take the pictures myself I would have gotten better pictures, but it was just too cold to stay outside
