Birds
American white
pelican
(Pelecanus
erythrorhynchos)
Harlequin duck
(Histrionicus
histrionicus)
CSC In California, the pelican only
nests at large lakes in the Klamath
Basin. Year-round habitat for the
pelican occurs in central and
southern California. Preferred
foraging habitat includes shallow
marshes, rivers, and reservoir
edges. The project is located
within migratory pathways
between summer and year-round
habitats.
CSC Breeding habitat includes clear
fast-flowing rivers and streams.
Breeding and wintering habitat are
located north of California.
Historical breeding grounds
included the west slope of the
Sierra Nevada where the species is
now only rarely documented.
Suitable habitat is present within the study area. This
species is predominantly migrating through the area
and may forage in rivers and reservoir edges.
Point count surveys conducted as part of the
relicensing surveys did not document this species;
however, in 2008, an incidental observation occurred
of seven individuals flying over Hell Hole reservoir.
Although suitable habitat may be present in the study
area, the species has a low potential to occur as the
study area is outside of the current and preferred
breeding and wintering range.
No species-specific relicensing surveys were
conducted for the harlequin duck and the species was
not documented during point count surveys, nor were
there any incidental sightings.
