The nutcracker

We walked along the beach with a raven for a little while this afternoon (14 March 2020).  It was searching the wrack line for potential food.  At one point the raven found a walnut (see below).  [I think the walnuts wash down the creeks and rivers and then end up on the beaches.]

 

The raven walked over to a piece of driftwood and held the walnut in place with its foot:

 

 Then it tried to open the walnut by hammering it with its bill:

 

This walnut was apparently too hard to crack, or the raven decided it wasn't worthwhile, so it left the walnut behind and started searching for something else.
