Not the greatest picture as this duck was way out in the middle of the lake, but Tim wanted to try to get a shot of it despite the distance. I’m just guessing, but could it be a female bufflehead? We’ve never seen them before at Constitution Gardens, nor did we see the showier male that day.

Best to view in "Original" because other versions resized by PBase are decidedly
unsharp.
