Abstract: The brood stage song of black stork were measured and analyzed during March to May,2014.The results showed that:the brood stage song could be divided into two types including normal songs and scared calls,which had no obvious difference in the structure of the verses that the convex type note came after first note and end with flat note.The overall frequency trend on the song was being from low to high and then high to low.There was no significant difference between normal songs and scared calls in duration of verse,number of notes song and time interval between the notes(P>0.05).By comparison,there were highly significant differences in duration of note,maximum frequency and minimum frequency(P<0.01).Different meanings could be conveyed by different the verse type or note repetition in black stork,namely that the verse type could be changed by changing the number of convex type note and flat type note.
