Let us not forget the warning that the film opens with:
In 1963, Alfred Hitchcock made a motion picture entitled ‘The Birds,’ a film which depicted a savage attack upon human beings by flocks of the winged creatures. People laughed.
In the fall of 1975, 7 million black birds invaded the town of Hopkinsville, Kentucky, resisting the best efforts of mankind to dislodge them.No one is laughing now.
