When my kids were little, we put out plastic Easter eggs for an Easter egg hunt, then left for Church. Most of the eggs had chocolate in them, like Hershey's kisses.
We came back to an egg hunt disaster. Maybe a dozen crows cawing and flying around (yes, some of them were there when we put the eggs out earlier), and the kids were finding open eggs with all the chocolate gone.
But, apparently, crows don't like Smarties or Lifesavers.
Back in 2003 when Ms1995hoo and I took a vacation on Kauai we were playing golf at the Prince Course and when we got some hot dogs at the turn, the snack bar attendant warned us not to leave any food in the cart when we went to putt or else the roosters that are all over the island would steal it. We followed his advice. I still wish I had taken my camera to the green with me because as we were walking to the green, I looked back at the cart and saw three roosters running over to it. They jumped up onto the cupholders and started pushing around the stuff on the shelf looking for food. When they didn't find any, they stood on the floor on the driver's side of the cart staring at the green almost as if they were glaring at us for not being stupid enough to let them steal our lunch. (Thankfully they didn't hop up and crap on the seat.)
