Ring-necked Duck

Ring-necked Duck - Aythya collaris

This duck has a confusing name. The ring is around the bill not the neck. Apparently the duck was named by an ornithologist who had access only to museum specimens. Even so, where is the ring?
These ducks are divers and the Ring-necked use only the feet (not the wings) for underwater propulsion. The feed primarily on vegetation
The white eye-ring is well demonstrated in this female.
