Heracles' 6th labour was the Stymphalian Birds. Eurystheus told Heracles that he had to drive away an enormous flock of birds which gathered at a lake near the town of Stymphalos. To get your head around how difficult this task was, you should know that some versions of the legend describe the Stymphalian Birds as vicious man-eaters, equal to lions in their fierceness.
So... Heracles arrived at the lake and had no clue of how he was going to complete his task. The goddess Athena came to his aid and gave him a pair of krotala (bronze clappers similar to castanets). These were no ordinary krotala though, they had been forged by the god Hephaistos.
Heracles climbed a nearby mountain, clashed the krotala loudly, and scared the birds out of the trees surrounding the lake. As they took flight he shot them with either a slingshot or a bow and arrow.
he was a strong, powerful man that could do almost everything
