Pivot table/chart row multiple records question
 

Ok, so here is my problem. I hope someone can help.
I have a large dataset of biological data. In each row are fields describing
Bird Species, number of individuals, and a behavior code. I want to create a
table/chart that reads each row in reference to the number of individuals as
well as the behavior. For example if a row contained a species code and the
number of individuals greater than one, I want the pivot table to register
that species as many times as the number in the individuals column, not
simply as one record of that species.
So far I can only think of inserting rows and manually copying the data
making a row to reference each individual. There has to be a better way as
there are currently 2700 records and that would take forever. Is there any
way to format the pivot table to do this for me? Thank you for any help you
can provide.
