The (for me) less familiar bird (especially in freedom) adds something unique to this shot, and again the lighting creates a very subtle effect in this bird's wing. The turbulence, widening his( (her) wingtips adds the dynamism to it. Yet I also feel something is missing. Not sure what, and I must admit I'm really searching for something which might not even be there. (that's what you get when you're uploading such good shots everytime...:) Great shot.
