- Comments:
Although similar to Western Grebes, Clark’s Grebes in breeding plumage can be
distinguished by orange bills and dark caps that do not extend to the eye. In wintering
plumage both birds are similar, although bill color may still reliably be used to
differentiate them. Clark’s Grebes are less common in the northern and eastern Great
Plains than Western Grebes. Western and Clark’s grebes were once considered to be the
same species. However, differences in vocalizations and appearance and a tendency to
forage in deeper water than Western Grebes have led to classification as different
species.
