326 BLACKBURNIAN WARBLER 



The quality of the Prairie's song suggests that of 

 the Black-Throated Green and the Black-Throated 

 Blue, but each is distinct. The Prairie's is a 

 slow, regular, ascending scale ^^ ; the Green's, 



as given by Mr. Burroughs, is ^/ ; 



while the Blue's is composed of three phrases, 

 each in descending scale, \ \ \ . 



Blackburnian Warbler : Dendroica blackburnice. 

 . (See Fig. 185, p. 346.) 



Adult male, throat and breast, patch in crown and on cheeks, 

 bright orange ; back black ; wings and tail largely marked with 

 white. Female and young, similar, but duller. Length, 5 

 inches. 



GEOGRAPHIC DISTRIBUTION. Eastern North America ; breeds 

 from northern Minnesota, northern New York, and southern 

 Maine northward to Labrador, and southward along the Alle- 

 ghanies to South Carolina ; winters in the tropics. 



The Redstart's name of ' Candelita ' might 

 well be applied to the Blackburnian, for it is not 

 only one of the most beautiful of the little War- 

 bler butterflies, but its flaming orange-red throat 

 might easily suggest a torch in the forest. 



The song of the Blackburnian has several 

 forms. Mr. Torrey says that one ends with zip, 

 zip, another begins with zillup, zillup, and a third 

 " runs up the scale to high Z."
