Actually, tool-making is regular in another crow, the New Caledonian Crow 
Corvus moneduloides.  I can claim a bit of second-rate renown as the 
discoverer of the fact that this crow uses tools - it was the subject of my 
first scientific paper - and some decades later a New Zealander, Gavin 
Hunt, found that the crows actually make a variety of tools, used to hook 
insects out of crevices and hollow limbs.
