This medium-sized diving duck is 15 to 18
inches long, has a wingspan of 27 to 31 inches,
and weighs between 1 and 2½ pounds.
The bill is bluish with a small black tip, the
eyes are yellow, and the legs are grayish with
dark gray webs. During the breeding season the
male has a black head, chest, and rear end, and
gray sides. The female is drabber and more brown,
with a white patch at the base of the bill.
The breeding range of the lesser scaup extends
from central Alaska to Hudson Bay southward to
Minnesota, northern Colorado, and extreme
northern California. Its winter range extends
across the southern United States, southward
through Mexico into northern South America, and
throughout the Caribbean.
The lesser scaup prefers open stretches of
fresh water in the summer, but can be found on
either fresh or brackish water in the winter.
The nest is a bowl of grasses or other
vegetation, lined with down, placed either
directly on the ground or in a mound of
vegetation over water. A typical clutch contains
8 to 10 pale to dark olive or greenish buff eggs.
Chicks are capable of diving under water soon
after hatching, but are too buoyant to stay under
for more than a moment or two. By the time they
are 5 to 7 weeks old, however, they are able to
dive for up to 25 seconds and swim underwater for
up to 60 feet.
The diet of the lesser scaup includes aquatic
plants and insects, seeds, snails, clams, and
genus & species Aythya affinis
