Hi Jill,
Another good suggestion! Didn't immediately occur to me but yes that would
also be tool use. New Cal Crows actually make their tools though, and
adjust their design to fit the job they want it for, so they are a fair bit
more advanced than picking up a stone to bash an egg or snail shell in.
Here's an example from a lab studying their behaviour:

<http://www.youtube.com/watch?v=TtmLVP0HvDg&feature=related>The crow is
given a tool (piece of wire) not up to the job and quickly figures out how
to make the right tool to solve the problem! The same behaviour is possible
to see in the wild though, as seen in David Attenborough's Life of Birds:
