Conservation

Conservation Low ConcernThere is little information on Red-necked Grebe population trends and numbers. The North American Waterbird Conservation Plan rates the species a 13 out of 20 on the Continental Concern Score and lists it as a Species of Moderate Concern. Red-necked Grebe is not on the 2014 State of the Birds Watch List, but are listed as Endangered in Wisconsin. These birds are susceptible to contaminants, such as organochlorines and heavy metals, that accumulate in tissues of prey species. Habitat loss for agriculture, roads, and development is also a threat to the species. Back to top
