Continuity mistake: As the birds fly out of the fireplace the silver ashtray on the table to the right of Mitch moves closer to him. (00:54:35)
Continuity mistake: The napkin that Cathy has under her plate changes position and becomes more spread out between shots as the birds fly out of the fireplace. (00:54:35)
Continuity mistake: When Melanie looks over at the fireplace and sees the lone bird standing there the logs are brand new and ready to be burned. When the rest of the sparrows come down the chimney the logs are burnt. (00:54:40)
Continuity mistake: There are two red books on the living room table next to Mitch's napkin. No one goes near them but later in this scene when everyone has left and the birds are flying around Mitch's dinner plate is there but the red books are not. (00:54:45 - 00:56:10)
Continuity mistake: Lydia puts her plate of food on the table in front of her as she gets up. She never touches it again, but later on in the bird attack the plate of food has been moved onto the couch near Melanie's plate in front of the red pillow. (00:54:50)
Continuity mistake: As the birds start flying around the room Lydia gets up and the green pillow behind her is on the left and the red pillow is on the right. When Mitch overturns the table the red is on the left and the green on the right. (00:54:50)
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 the birds fly out of the fireplace, the pillows that Lydia was sitting on have been fluffed up between shots. (00:55:15)
Continuity mistake: As he places the table over the opening of the fireplace Mitch's hands change position between shots. In the second shot he's holding the leg of the table, in the first he's not. (00:55:15)
Continuity mistake: Mitch takes two pillows from the couch and stuffs them into the openings between the fireplace and the table. Right after he does this each pillow falls but in the later shot the crew has tacked them up again in different spots. (00:55:15)
Continuity mistake: Mitch picks up the table with both hands holding the legs and this is how he places it up against the fireplace. Later we see it again as everyone exits the house and the table has been moved 90 degrees so that one lone leg is now at the top. (00:55:15)
Continuity mistake: Mitch puts the table up against the opening of the fireplace twice. The first time the bottom of the table is pushed up closer to the fireplace than the second. (00:55:15)
Continuity mistake: Earlier when the birds come out of the fireplace Mitch puts his plate of food down on the table in front of him. Later when he turns the table over, the plate of food is not there. (00:55:15)
Continuity mistake: When the birds invade the house from the fireplace Melanie's hairdo is completely messed up. In the very next scene with the policeman, Melanie's hairdo is perfect. (00:55:32 - 00:56:00)
Continuity mistake: In the scene with the policeman, Melanie suggests that she should stay for the night. Look closely at the mantle above the fireplace to in the right of the picture there is a jar with something sticking out of it. In the previous shot this jar is empty. (00:55:55 - 00:57:45)
Continuity mistake: At the end of the bird attack Melanie gets Lydia and Cathy out through the side door. If you look to the left of the screen the wall behind and around the lamp where the painting hangs is dark. In the last shot of the birds flying around the painting is lit. (00:56:00)
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: In an earlier scene as Melanie plays the piano and Cathy stands there look closely at the drapes on her left. In that scene the drapes were right up against the edge of the wall, now as Mitch checks the windows before the last attacks they're pushed back several feet. (00:57:30)
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: In the close-up of Melanie as she watches Lydia try to fix up the place after the bird attack there's a bird caught in a pleat on the drapes behind and to the right of her head. At first the pleat goes to the right but later as she walks over to Mitch the bird and drapes have been rearranged so the pleat goes straight down. (00:57:35)
Answer: The movie takes place in the 1960s, so presumably gas pumps worked a bit differently back then. This is also a small town and probably the gas station had not modernized. There may not have been automatic shut-offs, or if there was, it was faulty.

The automatic shut off is in the handle of the hose. When a person grips the handle they have to lift a levered switch to allow gas flow; the lever is spring loaded so that if it is released the gas will stop flowing. I have looked at older antique gas pumps and they are all the same; even the visible glass gravity flow ones. If that hose was dropped the the gas should have stopped flowing.
