I got this idea while waiting for my husband to finish at his job.  This bird is looking for his lunch.  This fish are aware of their dilemma and conspire to hide by pretending to be the rocks under water holding up the branch that the bird is perched on.  So far, they have been successful.

This drawing was done using lead hardnesses 6h,4h,2h,2b,4b,and 6b on a 20×14 cold press board.
