Anyone able to identify to following egg for me? It was located on the edge of a mudflat. My current guess is Killdeer since I have seen fledglings in the area recenting, but I don't know anything about egg identification. http://williamhblackburniibirding.shutterfly.com/pictures/162 http://williamhblackburniibirding.shutterfly.com/pictures/161
