I used a Canon 7D with a L 100-400 mm. lens on 2-23-2013.I photographed this eagle in a location i do not get to very often. It was very good to see many eagles,ducks and seagulls. I have photographed eagles in this very same tree for many years now and it is always a challenge because of so many branches. I think it is worth the effort. I counted 13 eagles in sight at one time. Wow! Very few were in my camera range or in the open. I photographed this in Winneconne,Wisconsin.
