Pigeons
From Muppet Wiki
Muppet pigeons have made several minor appearances on Sesame Street.
Two pigeons appear singing back-up in a series of 'coo's in "Keep the Park Clean for the Pigeons."
A pigeon also made an appearance in the 1992-2003 Sesame Street closing credits, and the same pigeon is also seen in the current opening sequence.
Another pigeon, redesigned, but retaining the basic style, appeared in Episode 4033, bobbing along to Cookie Monster's opening song. He was voiced by David Rudman in this appearance.
