Captured this morning on Sanibel near the fishing pier. I am woeful at identifying shore birds, but this one appears to be a female Black Bellied Plover in Winter plumage to me. I was using a BLUBB in a Frisbee as a groundpod. Image is untouched except for crop.
Canon 1DsMII, ef 300mm f/4, f/4, 1/160, ISO 100.
