Nature never ceases to amaze, and here's a prime example.
This video is part of a PBS documentary called A Murder of Crows. In it, researchers put a crow to the test, challenging it to use tools to get a piece of food.
To get the food, the crow has to pull up a string to get a short stick, then use the short stick to get a long stick, and use the long stick to get the food.
According to PBS, it's the first time this experiment has ever been tried.
