The story of The Thirsty Crow is about a crow who finds a pot of water but can't drink it because the water level is too low. The crow uses his wits to come up with a solution and quench his thirst. The story's moral is that "where there is a will, there is a way". 

Here's the story:

On a hot summer day, a thirsty crow flies around looking for water 

He finds a pot with a narrow mouth and low water level 

The crow can't reach the water, so he picks up pebbles and drops them into the pot one by one 

As the water level rises, the crow is able to drink and flies away
