FEMALE BUFFLEHEADS (BUCEPHALA ALBEOLA), GREEN, MICHIGAN, MAY 17, 2010
SMC Pentax-F* 300mm f4.5 ED (IF)
1/1000 sec. f8
Up to this spring we hadn't seen Buffleheads in these parts, and have been surprised to see them almost every day in Lake Superior outside our cabin. They're the smallest diving duck in North America, and the bird books say they evolved downward in size in order to hole up in the tree nesting cavities of Northern Flickers. They're growing more common, partly because they're too small and gamey for good eating.
