After my lovely bride and daughter came home from a local pond with a crazy story about a bird who fishes, I had to go check it out. The rascal really fishes. When you give him some bread, he walks out onto a rock, and tosses in the "bait" to lure in a fish. When a bream eats the bread, he scoops him up and has dinner.
Now that is very neat.. Not only is that tool use, but it shows it took a lot of independent thought and reasoning capabilities to figure out how to use the bread as bait.
Anyways I found it neat and thought I would share
