Open encyclopedia reference
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".
Western grebe fossils from the Late Pleistocene of southwest North America were described as a distinct species, but later ranked as a paleosubspecies Aechmophorus occidentalis lucasi. Later studies found them to fall within the variation now known to exist in today's birds.
