My main camera has gone back east for repairs, so I am using my old backup body.
The ring-necked duck (Aythya collaris) is named for a faint, chestnut-colored ring around the base of the black neck on breeding males, which is often difficult to see in the field. They are commonly known as "Ringbills" due to the distinct white band on their blue-gray bills, a more prominent feature than the neck ring.
