These running ducks sort of freak me out. I yelled at them to start waddling. When they ignored me, I threatened to attach little arms to their sides to make them look proportional. Wikipedia says only females quack, well at least louder than the men. Kinda reminds me of another species; yep, those silly dolphins! Though I don't use Instagram, these video really resonated with me: http://www.vh1.com/music/tuner/2012-12-04/nicklebacks-photograph-gets-college-humor-ed-look-at-this-instagram/. Especially where he is trying to get a picture of a duck, and it won't stand still.
