The range of Clark's grebe, Aechmophorus clarkii, is very similar to that of its close relative, the western grebe. It breeds in California, the northwestern United States, and the north-central United States, as well as in southwestern Canada, south-central Canada, and areas of Mexico. The species winters along the west coast of North America, from Alaska to northern Mexico. Clarke's grebe is a fairly common breeder in northern Utah. Preferred habitats of the species include lakes, marshes, and coasts.
Clark's grebe is a colonial nester that nests on large lakes; nests are typically built on vegetation in or near the water. A clutch of three or four eggs is laid by the female and then incubated by both parents for about 23 days. Both parents tend the young.
This grebe is an excellent swimmer, and much of its food is obtained from the water. Fishes make up the bulk of the diet, but invertebrates found in or near water are also consumed. Clarke's grebe can be distinguished from the western grebe by: 1) white (not black) around the eye and 2) a yellowish-orange (not greenish) colored bill.
