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.
While Ernie has appeared in many of scenes without Bert, Bert has not been seen without Ernie quite so often. Notable exceptions include the songs "Doin' the Pigeon," "The Subway," "Bert's Blanket," and "Stick Out Your Hand and Say Hello" with Rick Moranis, as well as occasional Muppet/Kid scenes, such as discussing emotions with John John.
Some of Bert's memorable moments include riding with Ernie in a plane in Follow That Bird, and interrupting The Adventures of Elmo in Grouchland whenever it looked like the movie was becoming unsettling.
Bert's extended family includes his identical twin brother salesman Bart, infant nephew Brad, and several unseen relatives, including his Aunt Matilda, Uncle Bart (who gave Bert his first paper clip), and great-great-grandfather Mountain Mike. The album Sesame Street Sing-Along! also refers to Bert's Uncle Louie, who lives on a farm.
Play With Me Sesame
Bert was one of the hosts of Play With Me Sesame. On that show, he often played games on a computer, such as "Pigeon Patterns" and "Perfect Pairs" (the latter of which involved matching socks). He also showcased "oatmeal art" from kids.
In Christmas Eve on Sesame Street, Bert decided to give Ernie a soap dish for Christmas so that his Rubber Duckie would stop falling into the bottom of the bathtub. However, as he had no money, he made a trade at Hooper's Store, where he traded his paper clips for a soap dish. At the same time, Ernie decided to give Bert a cigar box to put his paper clips in and traded his Rubber Duckie in order to get one. However, Mr. Hooper could see that neither of them was happy with trading their things, so he gave them their things back on Christmas Eve.
In The Muppets: A Celebration of 30 Years, Bert and Ernie introduced clips from Sesame Street.
In Sesame Street: 20 and Still Counting, Bert and Ernie got a new video camera. Bert initially wanted to use the camera to make some pigeon videos, but Ernie wanted to use it to make some Sesame Street videos (Bert wonders, "Who wants to see Sesame Street on TV? We can look at it outside our window every day!"). However, Bert eventually liked the idea and directed the footage.
Bert served as director in Elmopalooza.

Bert is a Hand-Rod Muppet, a puppet which is controlled by both hands. The puppeteer's dominant hand goes into Bert's head, operating his mouth, and at times, facial features. The puppeteer's less dominant hand controls the "arm rods", thin rods connected to Bert's hands.
- Bert made special appearances in two Muppet Show episodes: episode 102, (where he sang "Some Enchanted Evening"), and episode 518.
- "I remember in the very beginning, we first built these characters and then we were trying to decide who should do which", said Jim Henson in the 1984 documentary, Henson's Place. "I remember trying Bert and Frank tried Ernie for a while, and then we settled on the present arrangement. I can't imagine doing Bert now because Bert has become so much of a part of Frank ...In the beginning [of Sesame Street], Frank didn't like Bert. He felt Bert was too dull. But then after a while, he realized that Bert's dullness was really a lot of fun, and he got into this dullness thing and turned it into this wonderful personality." Frank Oz said in the same program, "Bert is a very boring facet of myself... I don't think I would latch onto that one character as being me."
