Great Meadows List Birding

I'm not much for life listing, though I do get a distinct brain thrill when I see something new. So today I stopped at Great Meadows on my way home precisely to check off some boxes, er, I mean gain new wildlife experience. Great Meadows in mid-fall is a sure thing when it comes to ducks and other water birds, and as a newbie I still have so much common goodness to see.
So, check off:
American Coot,

Green-winged Teal,

Northern Shoveler,

Pie-billed Grebe,

and whatever this is.


I'm going to guess Red-necked Grebe Just another PB, I think, now.
