bufflehead

Buffleheads Bucephala albeola, small diving ducks, are migrating through Minnesota now.  They nest north of here, so I assume these  two males stopped today for rest and food.  The pond is a perfect place for a respite on a cold snowy day. Maybe they found it warmer under the surface; they seemed to stay under for 12-15 seconds. Judging from the geese and other ducks feeding here, the Buffleheads must be finding nourishment as they dive in the pond.  I was trying for a photo of both, but they were constantly diving again, and too quick for me.
