Are you sure Phillip? I can only recall the Rhesus monkey of Japan
described re. this behaviour. And interestingly this was not common sense
or instinctive to them generally. One monkey (I forget her name) worked out
the process of cleaning rice, probably by accident, and the rest copied
her. This procedure soon spread and became part of their monkey culture.
