Bert is Ernie's best friend and roommate on Sesame Street. The pair share the basement apartment at 123 Sesame Street. In contrast to the practical-joking, extroverted Ernie, Bert is serious, studious, and tries to make sense of his friend's actions. His own passions include reading Boring Stories, collecting paper clips and bottle caps (especially the rare Figgy Fizz), consuming oatmeal, and studying pigeons. While Ernie's best companion outside of Bert is Rubber Duckie, Bert has his pet pigeon, Bernice. True to his detail-oriented, organized mind, Bert is president of the National Association of W Lovers. Unfortunately for Bert, his nose has come off of his face on a number of occasions. He has a distinctive,bleating laugh.
