what kind of bird is woodstock

Woodstock, the character from the Peanuts comic strip, is a small yellow bird of unknown species. The creator, Charles M. Schulz, never specifically identified what kind of bird Woodstock is. Although Woodstock resembles a small yellow bird and some speculate he could be a canary or an American Goldfinch based on his color and tuft of feathers, his species is never confirmed and he is depicted as a unique character with poor flying skills. Snoopy, his best friend, also does not know Woodstock's exact species, and this remains part of Woodstock's charm as a one-of-a-kind bird.
