DAY 210: CLEVER CARRION CROWS

The story is told of CARRION CROWS on one Japanese university campus.

Since the early 1990’s they (the crows, not the university guys!) have developed a marvellous technique for cracking the walnuts that they pick from the trees that grow by the roadside.   

They place the nuts in front of the traffic when the lights are red & the cars at a halt.  When the lights turn green & the cars begin to move, they fly to the top of the traffic lights & keep watch.  When the lights turn red again, they return to collect their booty, conveniently crushed. 

If the cars miss, the crows sometimes move the nuts to one side.   

If the cars go on missing, they sometimes take the walnuts up to the phone wires & drop them in front of moving traffic.  

Whichever clever method they use, they are determined to get the job done!  

Go, clever crows!
