Wonder why its called a Red-Winged Blackbird though, time to do some research ... excellent shot, I am struggling with doing birds other than Canada Geese and Ducks.
I also find birds tougher to shoot than it might seem. I had great luck practicing on dogs at the off-leash park before moving to athletes (crew), then to live insects, then to birds. I hope to move on to elusive mammals (bears, wolverines, martins, big cats etc.) at some point in the future.
