Big Bird is a Muppet character designed by Jim Henson and built by Kermit Love for the children's television show Sesame Street. An eight-foot-two-inch-tall (249 cm) bright yellow anthropomorphic bird, he can roller skate, ice skate, dance, swim, sing, write poetry, draw, and ride a unicycle. Despite this wide array of talents, he is prone to frequent misunderstandings, on one occasion even singing the alphabet as a single word (pronouncing it as in the song "ABC-DEF-GHI"). He would refer to grocer Mr. Hooper as "Mr. Looper", among other mispronunciations. He lives in a large nest behind the 123 Sesame Street brownstone and right next to Oscar the Grouch's trash can. In Season 46, the nest sits within a small, furnished maple tree, and is no longer hidden by used construction doors. He has a teddy bear named Radar.
Caroll Spinney performed Big Bird from 1969 to 2018. Matt Vogel began as an understudy in 1996 before becoming the character's full-time performer in 2018.
In 2000, Big Bird was named a Living Legend by the United States Library of Congress.
