观察细节
Seen at considerable distance (later only a little closer, when it crawled upon a sand bar) and backlit, which made identification rather challenging. Identified as female/imm type Ring-necked Duck based on overall shape and on gray bill with black nail and narrow white band across bill near tip. These features are barely but consistently visible in photos from various angles. Less visible in photos but visible in the field through a telescope was a faint eye ring.
