Drafting section on birds used in the film
The majority of the birds seen in The Birds are real, although it is estimated that more than $200,000 was spent on the creation of mechanical birds for the film. Ray Berwick was in charge of the live birds used in the production, training and catching many of them himself. The seagulls were caught in the San Francisco garbage dump and the sparrows used in the film were caught by John 'Bud' Cardos. However, the captured sparrows had be used alongside birds from pet shops to achieve full effect in the scene where they invade the house.

Drafting Production section
The Protagonist of the novella is a farm hand living in Cornwall and the conclusion of the story is far more pessimistic than that if the film with the reader knowing that the protagonist and his family along with humanity are going to die.

Initially, Hunter wanted the protagonist to be a school teacher but this ended up being the basis for Annie Hayward's character instead. Hunter organised his scripts by shots instead of scenes, although this did not affect the final film.

Hitchcock cut the last ten pages of the screenplay, some sources say possibly more, in order to create a more ambiguous ending. Initially he wanted the film to end without a THE END card, but was forced to include one before the film's full release.
