80% unsalted peanuts without shells, 20% seedless raisins with no added sugars. Anytime you see a crow or Raven, say "hey" "hello" in a short higher tone and slowly set a small handful on the ground at arms length. Step back slowly, and get about 10-15ft back and stay still and only use head gestures like quick upward flicks but not enough to frighten them. It's taken me a week to get 4 crows to follow me around the neighborhood while I walk Dotti.
