Yesterday morning I was at Lake Mirror in Lakeland, Florida. I watched this female Scaup dive time and again. Go down come up, quickly eat something, then down again. Soon I was pretty much able to time when the duck would break the surface and where it would be. So I readied myself focusing on the spot I believed she would surface. Success, she surfaced where I thought and I quickly focused and captured a burst of images. This one showed what she was diving for and eating... Snails. Comments and critique welcomed and appreciated. Thank you for viewing.
