n "Caged Bird" by Maya Angelou, the free bird is an extended metaphor for a free person, and the caged bird is an extended metaphor for an oppressed person. Angelou creates a comparison between the two birds to make her point. For example, a free bird that "leaps on the back of the wind" is a metaphor for being free to do anything, while a caged bird with clipped wings and tied feet is a metaphor for being kept from doing most things. Angelou alternates the focus of the stanzas between the free bird and the caged bird. This emphasizes the contrast between the two and highlights the emotions her extended metaphors convey.
