Room to Fly
The majority of my bird photography is done with a very long lens like the 400mm, coupled with a crop factor sensor of 1.6, and it's an effective 640mm. The typical goal is to capture frame filling birds in action, tight in the frame with little else to distract from the subject. The shots below are different in that they actually show more of the environment. There is room in the frame for the bird to soar, and it reminds me of their graceful flight in the golden morning light.
