This hawk ignored me as I moved closer and took quite a few shots as he was watching a lizard on the ground. This photo was taken with a Canon Rebel XTi and Canon 100-400 IS lens, handheld.
There's one of these at the local nature center near where I live (Sacramento, CA) and I've rarely been able to get close before it flew off. I usually only see it soaring above the trees. Great shot!
