Western Grebes

The Western Grebe, (Aechmophorus occidentalis, is a species in the grebe family of water birds.

Folk names include dabchick, swan grebe, and swan-necked grebe.

A paleosubspecies, Aechmophorus occidentalis lucasi, has been described from the Late Pleistocene of SW North America. As Clark’s Grebe was not considered a separate species until the 1990s, it is not completely certain that the fossils are correctly attributed to A. occidentalis vs. A. clarkii.


This is the largest North American grebe 56-74 cm (22″-29″) long. It is black-and-white, with a long, slender, swan-like neck and red eyes. It is easily confused with Clark’s Grebe, which shares the same features, behavior and habitat, and hybrids are known.
