What does it mean when a pigeon appears after someone dies?

There is no scientific evidence to suggest that pigeons appear after someone dies. However, there are many cultural beliefs and superstitions associated with pigeons and death. For example, in some cultures, it is believed that pigeons are harbingers of death or that they carry messages from the deceased to the living. Additionally, pigeons have been observed gathering in large numbers at cemeteries, which has led some people to believe that they have a special connection to the afterlife. However, there is no scientific evidence to support any of these beliefs.
