Despite the large differences in size
               and coloration across the their range,
               genetic divergence is low.

               Melospiz in Greek means song
               finch; melodia in Latin means
               a pleasant song.
          
         
         
         
            
               The song-sparrow’s exquisite warble 
            
               Is born in the heart of the rose —
            
               Of the wild- rose, shut in its calyx.
            
               Afraid of belated snows.
