There is little information on Clark's Grebe population numbers and trends. The North American Breeding Bird Survey examined populations of Clark's Grebe and Western Grebe together and found that there appears to have been declines in both species between 1966 and 2015. The North American Waterbird Conservation Plan estimates a continental breeding population of 10,000-20,000 individuals, and rates it a Species of Low Concern. Clark's Grebe rates a 13 out of 20 on the Continental Concern Score. The species is not on the 2016 State of North America's Birds' Watch List.Back to top
