La voix du rossignol

A partly-animated short film, a fairy-tale-like telling of why the nightingale only sings at night. A young girl who has caught a nightingale dreams about the nightingale and its mate, and comes to realize that birds are not made to be captive but free. In return for its freedom, the nightingale loans the child its voice for use in the daytime, which is why nightingales only sing at night.
