silashernandez99's Identifications

Mather Lake.
Photos taken near sundown. I have added two more photos to demonstrate how the wave action changes which individual looks bigger or smaller without any change in the order of the trio. Fourth photo added at Mike's request to show other birds for scale (uh-oh, it inserted into the second position instead of 4th). A Cliff Swallow shows in two photos. There were no other duck species anywhere close enough for my 400 mm lens + extender (=560 mm).
