← Stone-Throwing Chimp Thinks Ahead

This reminds me of my fathers Grey Parrots. Many Years ago, we found repeatetly stones in the Bathing Tub of a Group of young Greys. After observing the Group for some Days, the Riddle was solved. Some of the Parrots had learned to pick up stones an climb up on a Branch about 1.8 Metres over the bathing Tub (with a lot of effort). here they waited until an other Grey parrot wanted to drink or bath. AS soon as one was near enough, at least one Stone fell from upon and the Parrot was splashed wet, followed by a lot of Noise reminding of hysterical laughter... Sometimes a Parrot waited half an hour or longer to prank a co-parrot like this.
