Duck watching from a restaurant at Sunriver.
This decoy duck is bobbing nose to tail like a hobby horse. No self-respecting duck is going to be fooled by such a thing. But wait! Here comes a real duck. He swims toward the decoy. And bobs his head. Like he's greeting the wooden wader "Howdy, Fred, how's it floatin'."
No response from the decoy. The real duck passes by.
