Ernie becomes an honorary Birdketeer, but finds that Rubber Duckie wants to do more duckie things, since ducks are birds. Ernie and the Birdketeers get very involved in doing duckie noises and behavior that soon the Birdketeers become the Ducketeers group, who sing a song about waddling and quacking. Big Bird is upset at the competition at first, but then the two groups cooperate and make up a song that they can all sing together.
