A free bird leaps on the back of the wind
and floats downstream till the current ends
and dips his wing in the orange sun rays and dares to claim the sky.
But a bird that stalks down his narrow cage
can seldom see through his bars of rage
his wings are clipped and his feet are tied so he opens his throat to sing.
The caged bird sings with a fearful trill
of things unknown but longed for still
and his tune is heard on the distant hill
for the caged bird sings of freedom.
–Maya Angelou, from “Caged Bird”
