When we moved in, one of the (many, many) things the previous owners left behind was a glass jar about a third full of stale peanuts, with the words "for crow" written on the lid.

I left a few nuts out in obvious places a few times, but all I saw were squirrels, who would take some, leave most, and give me this look like "You're doing it wrong." Then, yesterday evening, I was walking along the side of the house and I saw a crow perched on the fencepost, looking pointedly at me. The crow watched me walk to the door, and go inside to retrieve the jar. I came back out and placed some peanuts on a flat rock on the ground, but the crow gave me the same look as the squirrel: "You're doing it wrong."

So I put some peanuts on the fencepost, and that was acceptable. Today I'm going to see about something a little nicer than stale peanuts.
