Ducks are a species of aquatic bird.
The Muppet Show
On Sesame Street, several different, more cartoonish ducks have appeared regularly, beginning in the 1980s. One is a blue and orange duck, originally performed by Kevin Clash; the character was later named Alfred Duck.
Another duck who has been seen regularly is white, with orange hair and some orange features. In the 1980s, the duck was occasionally seen as The Amazing Mumford's assistant. In a Season 37 sketch, the duck (performed here by Fran Brill) reveals her name to be "Jamie Foxx," sharing the same name with the actor (and a fox).
A more feminine looking duck, with pink hair and purple feathers, and a yellow duckling have also appeared in recent years. All four ducks appeared in the song, "Elmo's Ducks."
Rubber Duckie remains the best known Sesame Street duck, however.
