Color: Adult Trumpeter Swans are all white, except for black eyes, black legs and a black bill that has a pink stripe along the edge of the lower mandible. The male swan is called a cob; the female is called a pen. The sexes look alike, though the male is slightly larger. A swan in its first year is called a cygnet, and is grayish in color until it is about a year old, when it turns white. In their first summer, Trumpeter Swan cygnets have pink bills with black tips; the bills turn all black during the first winter.
