What does a sparrow coming to your window mean?

Answer 1

If any bird flies into the glass pane, that means that it sees its reflection in the glass and thinks that it is another bird coming to steal its territory, or such. There are stick-ons that you can buy to avoid that because the bird might hurt itself. If you mean that it is only flying near to the window, and it is familiar with you, or someone in your household, then it could be coming for food. If you have feeders up already, then it could just be wanting to tell someone that the feeders are empty.

Answer 2

Sparrows come to take a dying person's essence much like a whippoorwill will call until the death (superstition) read Stephen King's "The Dark Half"

Answer 3

It got confused, more likely than not. Birds in the house have no real bad luck meanings.

Answer 4

your windows are immaculately clean
