you hadn't seen that one and its brothers and sisters?
Heck those are the NORTHERN BLACKS DUCKS.....main migration route north to south is right through your "duckinot line" of Migration observers.....since that one is in Florida I can't imagine how you, or your 24/7 wall of migration watchers, didn't see it as it waddled by......maybe look "down" next year?
Oh...and just because its "black" doesn't make it a "coot".....or a "scooter".....or even a "blade" for that matter.....
