WhoooOOOoooo....?

Apparently I have a new neighbor. I do not know what *kind* of bird he is... but when it's really dark outside at all hours of the morning, I hear a little whhoooOOOooo... whhooOOOooooo.... WHOOOOOOOOOOooo....My guess is Owl... or Dove. I'm secretly hoping he's an owl, cause I'd like to see him! If he's a dove, I'm getting a BB gun.
