Warbler that it is difhYult t<> tell where tin- difference 

 lies; but ;i certain he.-itanry n-;ir the ciul of tin- ' 

 nut-sided's song usually betrays its author. II i 

 is another variation which shows that the bird had 

 iwiM-il almost the whole structure of the typical song, 

 and, regardless of the whole tribe of Warblers with all 

 their musical traditions, had decided like the wilful 

 Scotchman to " gang his ain gait ": 



I might say now, with Mr. Cheney, " match that if you 

 can!" 



The voice of the Chestnut-sided Warbler is only mod- 

 erately clear, and is therefore far less penetrating than 

 that of the Yellow Warbler. Such a tone, too, implied 

 by the syllable chew or cher, reveals a quality sus- 

 piciously near the overtone. But, as a matter of fact, 

 there is no real overtone present in any of the bird's 

 notes. In a great number of the songs there are only 

 six syllables, but these do not otherwise differ from the> 

 common type as I have represented it here. Miss Ethel 

 Dame Roberta's " tsee, tsee, tsee, Happy to meet you!" 

 is analogous to another popular saying of the bird, I 

 irish, I wish, to see Miss Beecher! If there is any one 

 who can whistle that lady's name better than the Chest- 

 nut-sided Warbler he must be a ventriloquist of excep- 

 tional ability !
