Parking Lot Duck. Also know as lot ducks, asphalt ducks, etc.
Seagulls, are now to be known as parking lot ducks, when found on parking lots, and other asphalt surfaces. As far as anyone can tell the phrase was made up by Cory Goltiani, as he drove through a few parking lots dodging "the parking lot ducks" The phrase was an instant hit and now people all over are using it.
Good lord look at all those parking lot ducks waiting for garbage to eat!
