WHIP-POOR-WILL. 



category of Nature's music ; it is a perfectly rhythmical, 

 metallic whistle which could be written out intelligibly 

 by a series of dashes, thus : 



Whip-poor-will, Whip-poor-wil^Whip-poor-wi/f, Whip-poor will, Whip-poor-will. 



But these do not carry with them any idea of pitch, and 

 so perfectly does the bird conform to pitch as well as 

 rhythm, that one has no difficulty whatever in fixing 

 the key or the position of any one of the three tones. 

 Here is an example of two distinct intervals of a fourth 

 and an octave; it is perhaps the commonest form of the 

 song; 







Whip-poor-will, Whip-poor-will, Whip-poor-will, Whip-poor-will. 



But no two birds sing exactly alike ; listen and you will 

 hear a distant bird respond in a lower key, with a lesser 

 interval, and in slower time ; the form is fairly common ;

Then another individual very near at hand will consider 

 this entirely too slow, and start in vigorously and viva- 

 ciously, thus ;
