Visible crew/equipment: As it sits on the table you can see the reflection of a crew member moving in the coffee pot at the center of the screen when Cathy asks Mitch why the birds are attacking. (01:38:20)

????

Continuity mistake: Two seconds after the orange car explodes quite a few people appear who were nowhere nearby a second earlier. (01:25:35)

????

Continuity mistake: When the birds start to attack again Mitch starts to run out of the restaurant and the old drunk at the bar is asleep. In the next shot of Mitch at the door he's suddenly awake. (01:24:40)

????

Continuity mistake: As Melanie places the card for Cathy on the bird cage one bird appears on the lower perch that wasn't there before. In the next shot it disappears again. (00:22:30)

????

Continuity mistake: As they talk to the policeman Lydia rearranges the picture of her father above the piano. In the next shot a black bird appears next to the fallen statue on the left that wasn't there before. (00:57:30)

????

Continuity mistake: The tall structure on the hill behind the swing set has a lot of clouds around it. When we see it seconds later the sky is clear. (00:52:05)

????

Continuity mistake: Melanie walks out from behind the desk and goes into the hallway to get the nightgown to show Annie. No one ever flicked a light switch, but the hallway is now very well lit up. (00:46:40)

????

Revealing mistake: As Mitch drives off in his Galaxy 500, some spectators across the street are watching the crew filming. (00:08:00)

????

Continuity mistake: On the last leg of Melanie's journey just before she enters Bodega Bay she's driving on a dirt road, but they dub in the sound of her tires screeching on pavement as she negotiates the turns. (00:11:45)

????

Continuity mistake: When Lydia says to Melanie, "Do you think Cathy's alright at the school?" the two pictures hanging above her head disappear the next time we see her. (01:03:15)

????

Continuity mistake: As Mitch returns to the living room before the lights go out, there's much more wood in the pile than before when he was putting it into the fire. (01:44:05)

????

Continuity mistake: As Melanie leaves Mitch's house, the barn alternates between having a blue sky behind it and having clouds behind it. (00:23:00)

????

Audio problem: They use a different overdubbed tone for the bell on the door of the general store when the manager opens it. Before as Melanie walked into the store we heard the real sound. (00:13:10)

????

Continuity mistake: When Melanie shows Annie the nightgown she bought, there's a box directly behind Melanie's brandy glass. Now it's silver, but before it was turquoise. (00:46:55)

????

Continuity mistake: As Melanie and Mitch walk down the hill Annie and Cathy are standing in the middle of the yard with two other children between them and the lounge chair. In the next shot as we see Lydia carrying the cake, the two children disappear and Annie and Cathy have moved to the left closer to the door. (00:51:35)

????

Continuity mistake: After she throws up, Melanie brings Cathy back out from the bathroom and the scales on the table and the curtains behind them are very well lit. No one turned off any lights, but a few shots later when the birds start the next attack Melanie stands and the scales and curtain are in the dark. (01:40:10)

????

Revealing mistake: As Melanie walks up the stairs she's pointing the flashlight out in front of her but it's able to illuminate her face like a spot light. (01:46:50)

????

Continuity mistake: No one touches the two yellow buoys on the end of Mitch's doc, but after Melanie leaves the birds in the house they've changed position relative to the wooden planks underneath. (00:23:10)

????

Continuity mistake: Melanie hasn't been near her car since the attack on the children at the school. Now as she and Mitch pass it while walking to Annie's, we can see the front wheels have been turned all the way to the right. (01:29:50)

????

Revealing mistake: A fake bird, unable to fly straight, swoops down as Mitch saves Melanie from the phone booth. (01:27:45)
