 23-Sept. 27. SE. Minn., common T. V., May 8- ; Aug. 27- . 



Nest, of twigs, moss, rootlets, etc., lined with fine grasses and tendrils, 

 generally in spruce trees, about 6 feet up. Eggs, 4-5, white, more or less

The Black-poll is not the last Warbler to reach us in the spring, but 

 it is usually the last of the transients to leave us, the length of its stay 

 and its abundance making its passage one of the features of the spring 

 migration. In the fall it is even more abundant. Adults and young are 

 now alike in plumage, but they are to be confused only with the much 

 rarer Bay-breasts. 



Gerald Thayer (in " Warblers of North America") describes the 

 Black-poll's main song, from which there are many variations, as "a 

 string of six to twelve or more, short, equal and equally - divided sibi- 

 lant notes, cobweb-thin and glassy-clear, uttered rather fast; the whole 

 song smoothly swelling in volume to the middle, or the second third, 

 and then smoothly falling off."

 Center of the black crown, a line over the eye, patch behind the black 

 ear-coverts, throat, and breast beautiful rich orange; back black, streaked

 inner vane of most of the tail-feathers almost entirely white, except at the 

 tip; the outer vane of the outer feather white at the base; belly tinged with 

 orange, sides streaked with black. Ad. 9 . Resembles the d", but the orange 

 markings are paler, the upperparts are ashy olive-green streaked with 

 black and whitish; the white on the wings arid tail is less extensive. Im. d". 

 Resembles the 9, but has the orange markings dull yellow, the crown-patch 

 nearly absent. Im. 9 . Similar to the im. cf , but the yellow, markings much

 N., -31. 



Remarks. In connection with other markings, the large amount of 

 white in the tail, appearing on even the outer vane of the outer feather, is 

 characteristic of this species.

The Blackburnian is uncommon enough to make us appreciate his 

 unusual beauty. Coming in May, before the woods are fully clad, he 

 seems like some bright-plumaged tropical bird who has lost his way 

 d wandered to northern climes. The summer is passed among the
