Greater Scaup (Aythya marila) has a larger
size and smoothly rounded head compared to the Lesser Scaup, along with
a slightly larger bill with wider black tip. A green gloss can be noted
on the male Greater Scaup's head. This is a female. They are found on
large open lakes and bays and, being of the Family Podicipedidae, must
take a running start on water for take-off.
