The Birds (1963)

Chic socialite Melanie Daniels enjoys a passing flirtation with an eligible attorney in a San Francisco pet shop and, on an impulse, follows him to his hometown bearing a gift of lovebirds. But upon her arrival, the bird population runs amok. Suddenly, the townsfolk face a massive avian onslaught, with the feathered fiends inexplicably attacking people all over Bodega Bay.
