The yellow bird character who is Snoopy's friend in Peanuts is Woodstock. He is known for being small, chirpy, and always by Snoopy's side, despite not speaking any recognizable language in the comic strip.
Woodstock was the little bird in the Peanuts cartoon.
Assuming you mean the little yellow bird - Snoopy's companion is called Woodstock.
this question doesn't really make any sense because you didn't state who the yellow bird is and in what cartoon. Now Tweety is yellow and he is in a couple of the cartoons especially in loony tunes. Hope this helped.......
