It means that a blue jay has visited you.
dead
you parked near a tree and your window was open
Policeman Bluejay was created in 1907.
Upside Down Bluejay was created in 2004.
It means a peaceful passing of a soul.
It means the insect was looking for a place to land.
It could mean that the bird sees its reflection in the window and thinks that it is seeing another bird, or it could mean that, at some time, someone put out bird seed onto your window sill.
I'm surprised you had time to ask the question here before you found out. SPLAT.
Hide the window.
bad luck
blue
Bluejay is a pen name used by multiple authors, so it's difficult to pinpoint exactly what Bluejay has written without more context. It's recommended to specify which author or book you are referring to in order to provide a more accurate answer.
