Continuity mistake: As the children start running down the hill away from the school the road is wet. In the next shot of the same spot it's dry. (01:13:30)

????

Continuity mistake: When Melanie says to the store manager, "The little girl's name," a bunch of items appear to the right of the store manager, one named "Magic Puzzle," that weren't there in the previous shot. (00:14:35)

????

Continuity mistake: The stuff inside Mitch's barn is lit differently and moved between shots. (00:22:05 - 00:22:40)

????

Continuity mistake: The gas station fire in front of the pumps becomes much worse between shots as Melanie watches it from the phone booth. (01:26:20)

????

Continuity mistake: After Mitch and Melanie walk past the door that says, "Out to Lunch," look at the numbers on the front of the boat behind them you'll see that they change between shots. (00:26:15)

????

Revealing mistake: As Melanie drives up to Bodega Bay the birds are supposed to lean as the car goes around corners but the mechanism for the bird on the right gets stuck and reacts slower than the bird on the left. (00:11:00)

????

Continuity mistake: As Melanie pulls into Bodega Bay she makes a sharp right turn in bright sunlight but the shadow of her head never appears where it should be on the seat behind her. (00:12:00)

????

Continuity mistake: As they talk in Lydia's bedroom the inside part of the left window curtain is rearranged while Melanie is standing by the clock. (01:06:20)

????

Visible crew/equipment: After Melanie walks through the doorway, the camera moves backwards as she walks down the hallway. Its shadow moves across the doorpost to the left of the scales. (00:22:15)

????

Continuity mistake: As they talk in her bedroom and Lydia says, "Do I sound very foolish to you?", the pillows behind her are propped up differently between shots. (01:03:15)

????

Continuity mistake: As the birds are flying around the house we see in the close-up that the fireplace has three logs. The right half of the log in the middle moves up onto the log in the front between shots. (00:55:05)

????

Continuity mistake: As they go up to the restaurant to get help Melanie says, "I had a booster before I went abroad last May" and the background changes abruptly between shots. (00:26:15)

????

Continuity mistake: Lydia is holding her glove in her right hand and her pocketbook in her left as she walks into Mr. Faucet's room. The pocketbook never switches hands but when she runs out, she drops both of them from her right hand. (01:00:15)

????

Continuity mistake: As Melanie runs to Annie, the pile of papers on the left of her desk changes between shots and a blue booklet appears on top. (01:12:00)

????

Continuity mistake: Before Melanie runs back into the school to warn them about the birds, the sun was behind the school. Now her shadow on the steps is in the wrong direction, going in front of her. (01:11:45)

????

Continuity mistake: As Melanie walks into Annie's apartment we see the front door behind here to the left. Before the door had a shade on top of it, this door is different and doesn't have a shade or a space for it between the curtain and the window. (00:41:10)

????

Continuity mistake: As Melanie and Mitch walk past the side of the restaurant look closely at the second and third windows from the right. Now we can see right into the place through these but after they walk into the restaurant look behind the bar all three windows have drawn blinds. (00:26:25)

????

Continuity mistake: No one is sitting inside the window at the left of the restaurant as they walk by. In the next shot inside the restaurant there are people sitting there. (00:26:25)

????

Continuity mistake: In the close-up shots of the party scene the grass is much greener than in the wide shots, where some brown is mixed in. (00:52:30)

????

Continuity mistake: When the first bird perches on the monkey bars behind Melanie the sun is behind her as you can see by the long shadow she casts as she walks to the chair. In the close-up she casts a shadow in the opposite direction on the fence. (01:09:55)
