The Birds received critical acclaim. In recent years it has received a Rotten Tomatoes approval rating of 96%, with the consensus: "Proving once again that build-up is the key to suspense, Hitchcock successfully turned birds into some of the most terrifying villains in horror history." Film critic David Thomson refers to it as Hitchcock's "last unflawed film".
Humanities scholar Camille Paglia wrote a monograph about the film for the BFI Film Classics series. She interprets it as an ode to the many facets of female sexuality and, by extension, nature itself. She notes that women play pivotal roles in it. Mitch is defined by his relationships with his mother, sister, and ex-lover – a careful balance which is disrupted by his attraction to the beautiful Melanie.
The film was honored by the American Film Institute as the seventh greatest thriller and Bravo awarded it the 96th spot on their "The 100 Scariest Movie Moments" for the scene when the birds attack the town.
