Western
Grebe
Aechmophorus occidentalis

Description 22-29"
(56-74 cm). A large slender grebe with a long neck. Blackish above with black of
cap extending below eyes; white below and on front of neck. Bill long, slender,
and greenish yellow. Long white wing stripe shows in flight. See Clark's Grebe.
Voice A
rolling kr-r-rick, kr-r-rick! sounded most often on breeding grounds but
sometimes heard in winter.
Habitat Breeds
on large lakes with tules or rushes; winters mainly on shallow coastal bays and
estuaries.
Nesting 3
or 4 bluish-white eggs, stained brown or buff, on a floating nest anchored to
reeds. Nests in dense, noisy colonies.
Range Breeds
from British Columbia, Saskatchewan, and Minnesota south to southern California;
sparsely in Arizona, New Mexico, and Colorado. Winters along Pacific Coast from
southeastern Alaska to California, on Gulf Coast of Louisiana and Texas, and on
large river systems in West.
Discussion The
mating display of the Western Grebe is spectacular, with both members of a pair
paddling vigorously and churning across the surface of the water in an upright
posture. Sometimes many pairs in a colony display simultaneously. During
migration Western Grebes fly in loose flocks but spread out to feed during the
day. On their coastal wintering grounds these birds often fall victim to oil
spills and to insecticides that accumulate in their food, build up in their
bodies, and reduce their breeding success.
