Tom,
 
I have witnessed simillar behaviour.
One day I was at my Grandfathers place in Thornleigh,Sydney where there is some resident Ravens which nest in a large Blue Gum in his yard most years.
 
One day I heard a loud banging noise on the roof, and when I looked up I saw a raven with a very shiny white stone, the size of a small egg.
The bird would pick it up and drop it then fly up and drop it.
 
Later I went up onto the roof of the house and found a myriad of shiny round stones and many smashed roof tiles.
Interesting behavour.
