Today I went for a walk, and on my way passed near a cemetary. Next to the entrance was a crow sitting on a roof, looking down at a small faucet.

I had a feeling I knew what it wanted. I found an empty container, filled it with water and left it next to the faucet. Then I stepped back and waited. After about a minute the crow came down to drink. This made my day.

Who knows what other intelligent abilities humans might possess.
