The iridescent patch of purple on the cheek of this male Wood Duck (Aix sponsa) only flashed briefly at this exact angle. I was pleased that all of the other colors and textures came through well in this shot. The sunlight was very intense at that time.
This blue nosed fella is a male Ruddy Duck (Oxyura jamaicensis).
I think this next might be a variety of Muscovy Duck, but the color patterns and the head bulb are different from, and more attractive than (from my own perspective) what I'm used to seeing.
The Mandarin Duck (Aix galericulata, male) and turtle (gender unknown) seemed like companions, and looked contemplative, which put me in a similar mood.
When the duck began flapping its wings, I reacted as if it were a human crying "hey, look here!"
"You can shoot me, but don't ignore my slower pal!"
A scarlet ibis (Eudocimus ruber) can be a show stopper pretty much anywhere, but against a background of totally blurred greenery - wow!
