NPR: Inventor Trains Crows to Find Coins

In the fourth step, he gives the birds nothing. But the crows see that coins have been spread on the ground near the machine. This reveals what's special about crows. Squirrels, for example, look at the box a half-dozen times, then disappear to play in traffic. Crows make the connection: Pick up the coin, put it in the box and receive a reward.

Better than having them pluck out your eyes, I suppose.
