Granny Bird is Big Bird's grandmother. She is almost identical in appearance to her grandson except for her clothes, the gray feathers in her forehead, faded eyelids, and eyeglasses. In episode 3006, it is revealed that Granny Bird is Big Bird's grandmother on his father's side.
The puppet used for Granny Bird is a spare Big Bird puppet, and Caroll Spinney provides her voice. As Granny Bird's appearances are often alongside Big Bird, her voice is usually pre-recorded so that Spinney can perform Big Bird.
Big Bird has referenced "my grandmother" on Zhima Jie: Da Niao Kan Shijie, a Chinese co-production.

Soon, his sadness turns to fury and he starts yelling to relieve his anger. While he is yelling, Granny arrives, stating that she managed to get on another plane. Bob lets Big Bird know she's here, but he refuses to come out of his nest. Granny is surprised that he is angry at her and promptly leaves.
