According to superstition, when a bird flies into a home, it is a sign of some important message. If the bird is white or dies while in the home, it is a sign of impending death. However, if the bird poops on the occupant's head, it is considered good luck.
Some superstitions say that if a black bird flies through an open window into a home, it is a sign of misfortune. If the bird does not settle in one spot, it means the home has disincarnate souls. On the flip side, if a black bird builds a nest in the home, it is a sign of good fortune for the next year.
