Grey and yellow. Good color combo.
Seems weird that a wild bird would sit on the guy’s hand that way.
He’s probably holding the bird’s legs................
Re: 11 - that’s photographer’s grip used to hold the bird to make photography easier of the various feather tracts.
But I would deduct points for the person’s fingers being visible. The point of the picture is the bird. Just went out with a crew 2 weeks ago to band Eastern Screech Owls and my hands were not visible for pictures of three owls but were in one (hiss).
