Think of it as "The Terror of Tiny Town", but with an all avian cast. The feathered residents of Chirpendale are terrorized by an evil black crow by the name of "The Black Menace".
The film received an Honorary Award from the Academy of Motion Picture Arts and Sciences (the "Oscars") "In which artistry and patience blended in a novel and entertaining use of the medium of motion pictures."
