I was once on the balcony of the cafe at the modern art museum in Sydney, Australia, quietly drinking some coffee. A bright red bird landed on my table and was eyeing me closely.
I was thinking, "What in the world does this bird want? I don't have any food, and why would a bird want coffee?"
I figured out the answer. He made a bold grab for the sugar packet. It was too heavy to fly off with, so he just dragged it away from me, opened it, and ate it while I continued to drink my coffee.
