Continuity mistake: The shadow of the statue on the right of the piano changes between shots. When we first see it in this scene the shadow falls right in the center of the picture of father then as they all sit waiting for the attack the shadow falls on the right side of the picture. (01:40:25)

????

Revealing mistake: In the first shot of the children running down the hill looking from behind we see several children in the front of the pack (superimposed background) with fake birds tied around their shoulders. (01:14:00)

????

Continuity mistake: After Melanie says, "Oh Mitch," during the attack, they have a close-up of the knuckles of her left hand. The first time we see them they're scraped and bloody but the second time it's the palm and wrist and not the knuckles that are bloody. (01:48:50)

????

Continuity mistake: In the last bird attack Lydia and Cathy run past the drapes behind the dining the room table and they're hanging straight down to the floor. Before when we saw Mitch and Lydia sitting the drapes were crooked. (01:41:20)

????

Audio problem: As Melanie and the manager leave his store to look at the Mitch's house, they overdub the bell sound when he opens it but neglect to when he closes it. (00:13:15)

????

Revealing mistake: The birds on the floorboard of Melanie's car are fake. If you look closely at the one on the right it wobbles like a toy as she's driving. (00:10:00)

????

Visible crew/equipment: You can see a flash as the boom mike operator hits the light above the front door when Mitch runs back with the hammer and nails. (01:43:45)

????

Continuity mistake: As Melanie and Mitch get ready to leave the restaurant for Annie's the hat and coat on the coat rack cast a very dark shadow against the wall. When we saw this spot before there was only of very light shadow against the wall. (01:29:10)

????

Continuity mistake: As they await the last bird attack Lydia cleans off the coffee table and comes back and sits in the chair next to the piano. Her head looks left and then right between shots. (01:39:20)

????

Continuity mistake: As Melanie sooths Kathy she has a towel in her right hand that she drops on the green pillow to the left of the couch. We catch a glimpse of it lying there as Mitch runs to put wood in the fireplace. Melanie never touches the towel again but the next time we see it it's in the middle of the couch. (01:40:50)

????

Continuity mistake: As Mitch runs to get the hammer and nails for the front door notice the top leaf of the fern plant to his left. It gets rearranged in the next shot, as Melanie watches him, with one fern sticking out from the middle that wasn't there before. (01:43:45)

????

Continuity mistake: When Mitch puts the mirror up against the front door he hits the chair to the right of the door and knocks it out of place. In the next shot it's been moved back to where it belongs. (01:43:30)

????

Continuity mistake: As Mitch ties up the shutter, he goes over to Lydia. Look at the shades pulled up well above the middle of each window. Later when we see the windows again, just before the lights blow out, the right shade has been pulled down to the middle of the window. (01:42:45)

????

Audio problem: After leaving the card by the bird cage Melanie walks on the carpet over to the window to see where Mitch is. She just walked over that spot a minute ago and didn't make a sound, but now they dub in the sound of her walking on a hardwood floor. (00:22:35)

????

Continuity mistake: The drapes on the far wall of the dining room to the left of the dinner table have been straightened out during the scene but no one went near them. (00:56:10)

????

Continuity mistake: As Mitch goes out the dining room door to the garage there's a big oily, drippy stain behind and to the right of his head. In the next shot it's gone. (01:52:30)

????

Continuity mistake: When Lydia comes into the restaurant, the collar of her coat looks fine. In the next shot the left side of her collar is sticking up. (00:29:35)

????

Continuity mistake: When Mitch covers Annie's body with his jacket the back of it is not as dirty as it was a few seconds ago when they walked up to the school. (01:31:05)

????

Continuity mistake: As Melanie, Mitch and Cathy get into her car to leave the school, Annie's red mailbox can be seen out on the road behind them. In the next shot of them inside the car driving away the post is there but the red mailbox is not on it. (01:33:30)

????

Audio problem: When Annie says, "Did you drive up from San Francisco by the coast road?" her lips are mouthing something different. (00:17:55)
