Blue Jay is a bird who appeared on Sesame Street in Episode 4265 ("The Good Birds Club"). He initially bullies Big Bird but later becomes his friend.
He appeared in Happy to Be Me: An Anti-Bullying Discussion, and in press appearances on FOX News, CNN, and The Early Show with Big Bird and Rosemarie Truglio to discuss the episode.
While Matt Vogel performed Blue Jay in the episode, Joey Mazzarino performed him in the outside TV appearances relating to the episode.
Muppetized blue jays have appeared on Sesame Street as early as 1993, with two providing six tweets for The Count's "One Bark (and Two Meows)."
A blue jay also appears prominently in Episode 4221 (also performed by Vogel). The blue jay's background appearances include "Elmo's World: Birds" and a Super Grover 2.0 segment on pulleys.
