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.
