326 BLACKBURN IAN 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 Mackburnice. 

 (See Fig. 185, p. 346.) 



Adult male, tl^oat and breast, patch in crown and on cheeks, 

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

 white. Female and young, similar, but duUer. Length, h\ 

 inches. 



Geographic Distribution. — Eastern North America ; breeds 

 from northern Minnesota, northern New York, and southern 

 Maine northward to Labrador, and southward along the AUe- 

 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."
