Ravens are noizy and annoing and disturbing our sleep how to run them away?

Question:

Answers:
Nevermore.

Sorry, but I couldn't resist (I'm a Poe fan). Other than making noise yourself, or having something that moves periodically to spook them, I'm not sure how to get them to relocate. Do some research online and see if there are any good tips available...often when they are frightened away, it only lasts for a short while. Is there something on your property or near it that they find particularly appealing?
