Title Would Give Away

upon the fall evening of Novembers moon. there is the call that makes a small tune. some may guess it is a familiar sound. others may find it hard and never found. it is known through the the land far and wide. sometimes they are seen, sometimes they hide. many may think one animal i am speaking for. some may be fooled because how they do score. someone is saying this is easy and all should know. someone else is blinded by the words that show. what do you think of what I am speaking about. please take a guess and speak without a shout. no rhyme or reason to the guess you do make. please take your time to ponder for your sake.
