Excellent image. Light, head-angles, distant BG, action and behavior all working very well for you here. Though I don't think you clipped a toe on the right bird, I would have liked to see a bit more room on the bottom but that is a minor issue.
Using f/11 to get DOF ont he bird worked well here because the BG is far off and it is pleasing blurred. Well done image all around.
I really like this one Andrew. First off, a great moment captured. Then you have an excellent exposure with good detail in the whites. Good light. Nice eye contact. I could go on, but you get the idea.
