Lesser Scaup

Aythya affinis

The Lesser Scaup and the Greater Scaup are difficult to distinguish. Head shape is one way to differentiate them, but winter habitat can help too. The Greater is more of a saltwater bird and the Lesser a fresh water bird.

Pair bonds usually occur on the winter grounds and last until the hens lay their eggs. Then the males collect in bachelor groups to molt, leaving the hens in charge of child-rearing.
