Horned Grebe are common, but populations appear to have experienced declines between 1966 and 2015, according to the North American Breeding Bird Survey. There is little information on absolute population size, but evidence suggests that this grebe's breeding range is contracting. The species rates a 13 out of 20 on the Continental Concern Score. Horned Grebe is on the 2016 State of North America's Birds' Watch List, which includes bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats.
