Not being familiar with the layout at Estero Llano Grande, we arrived to find a nice group of ducks backlit by a hazy bright sky. Not optimum conditions, but it did offer some interesting shots. This Gadwall hen was coming in to join the others. Cropped from horizontal. I probably would have used some fill flash, but the day before I had dropped the Fresnel lens of my BB in a parking lot, and it blew into a mesquite thicket where I couldn't retrieve it. I did like the translucency of the primaries and fanned tail.
