American Coots, to be exact. They've been haunt the area recently. There were FOUR of them here that I caught on camera. Three hung together more, but one seemed more prone to roam off on its own at times. They're small, they're black, they have little white beaks, and they're very shy.
The gull is just above the left goose, and the coots are way in the back along the shoreline, four of them.
