My recent trip to Middle Creek resulted in being able to add another species to my photo archives.
A flock of Gadwalls were feeding in a pothole near the road. Not overly concerned about the nearby viewers and photographers, they approached near enough for decent photography. These images were captured with the Canon 600mm F4, at ISO400,f4,1/750.
From their actions they had more than migrating and feeding on their minds as a group of males pursued a single female relentlessly.
This particular shot was my favorite from the encounter.
