Intelligent crow story. 
I was at a park a few months ago and was talking with the lady that runs the concession stand there. She was telling me how for over a week strait, she came into work and found trash all over the parking lot and the grounds. She thought some obnoxious kids had come into the park after hours and trashed the place, and was about to file a complaint after it had happened every day for a week. But then one day while she was getting ready for another day at work, she heard commotion behind the building, and so she went to check it out. There she found a flock of crows, attacking the trash bags that had been taken out the night before. They would actually work together to lift a trash bag up out of the trash bin, fly up a few meters and then drop it, which would usually result in the plastic bag bursting open and exposing the "goodies" inside. She watched them for a while, and soon saw another silly bird take on a smaller bag by dragging it on the ground until the plastic bag ripped. They would then fight over their findings, and eventually leave remnants all over the grounds. Ah hah, she had finally caught these "kids" red handed!
Her colleagues got new trash bins with heavy lids, and it solved the problem. But my goodness, what naughty, yet intelligent birdies!
