Cataloging a species?

["Dave J" <>]

I was just noting the curious little mewing sound the gray squirrels 
are making now. Does a proper naturalist collect all the different 
sounds produced by a particular species and then attempt to explain 
where each one fits into the lifecycle of that particular animal? I'm 
sure there may also be regional variations to complicate the 
situation for many species? 

Thanks,

Dave
