They are seen flying when the Evil Queen is fleeing from the dwarves who are trying to save Snow White, who has already bit the poison apple while the animal friends warned the dwarves. They perch on another branch, waiting for the Evil Queen to die. They watch as the Evil Queen prepares to kill the dwarves by rolling a boulder on them. However, lightning strikes the edge of the cliff while the Evil Queen is cackling thinking she is going to win. The Evil Queen falls to her death, much to the delight of the vultures. At the end, when the Evil Queen falls to her death, they fly down to her body. They devour her off-screen.
The Evil Queen never had seen the vultures. So, she never knew that they had been following her and that they were planning to eat her when she died. Like most minor animal villains, the vultures are non-speaking characters. However, they are not-completely-evil villains since they only want to eat the Evil Queen who is the evil threat to Snow White, the protagonist of the movie. However, because of their sinister looks and grins and the fact that they think she is a harmless old peddlar woman, they are in fact evil. Unlike most animal villains who miss their prey, the vultures successfully get their prey in the movie because the Evil Queen died when she fell off the cliff, of course.
