…putting stones into a pitcher to raise the water level to be able to drink it ? It is not a fable , it is fact … _Now a study published in Current Biology reveals that rooks, a relative of crows, do just the same when presented with a similar situation._ [story](http://news.bbc.co.uk/2/hi/science/nature/8181233.stm) with video here. 🙂 ---
