Clark's Grebe is a diving bird with a long neck and pale face. During courtship, pairs run side by side across the water.
It has a slender neck, small body, black cap, white face around the eye, and straight orange to orange-yellow bill. The back is black, the underside white, and the eye red.
During courtship, pairs perform a synchronized running dance across the water. Two males may also perform this display together.
After breeding, many birds molt their wing feathers on lakes and become flightless during the molt. They move toward coastal habitats after the new feathers grow.
Both sexes build a floating mound of aquatic plants with a central hollow, anchoring it to vegetation, a submerged log, or a root. The clutch contains 2–3 eggs.
Both parents care for the young, and newly hatched chicks ride on the adults’ backs.
