Stellaluna is a young fruit bat who becomes separated from her mother and lands in a nest of baby birds, becoming an adoptive member of the bird family. She learns to act like a baby bird and struggles to accommodate to the family, but she never completely fits in. Eventually she is able to regain her identity as a bat, and she and her bird friends wonder together about friendship and being alike and different at the same time. When Stellaluna lives like a bird, is she a bird or a bat? How do we know? Can birds and bats be friends? Could we be friends with a bird or a bat?
