That is a well-known and well-documented behavior used by several corvids 
(and some other birds too) to get at hard-shelled food. I remember a case 
where so many crows started using a concrete airfield for shelling walnuts 
that it caused safety concerns (FOD = Foreign Object Damage).
Personally I think that the common Raven Corvus corax is probably the 
smartest corvid.
