Timid Wood Ducks

These guys are really spleeny. I'm surprised I got this close. (I use a 70-300mm zoom lens and had to crop excess junk off this to bring him in closer). He was whistling while padding away to the others you can't see beyond the brush there. Wood ducks do not quack...they whistle, cluck and "honk" in alarm as they fly off. I know that sound, too many times....
