 Fall Migration.

The Bird and its Haunts. Singing freely while he travels, one 

 need not follow the Black-throated Green to his northern home to hear 

 the delicious, little lazy drawl which, near New York, marks the open- 

 ing days of Warbler time. Now we may find him almost anywhere 

 there are trees, but, arrived on his nesting ground, he shows a marked 

 preference for conifers. 



About Cambridge, Mass., where the Black-throated Green is 

 among the most abundant summer Warblers, Brewster 6 writes that 

 its favorite haunts "are extensive, well-matured woods of white pines, 

 and rocky pastures growing up to pitch pines or to Virginia junipers." 



About Monadnock, Gerald Thayer writes, the Black-throated 

 Green is "a very common or abundant summer bird through all the 

 region, high and low; ranging from the pine woods of the lowest 

 valleys to the half open copses of spruce and mountain ash along 

 Monadnock's rocky ridge, 2,500 to 3,169 feet. High upon the moun- 

 tain, however, it is less common than the Myrtle, or even the Nash- 

 ville. Though decidedly a forest Warbler, it favors second growth, 

 and pasture-bordering copses, rather than the very heavy timber, and 

 is particularly partial to dry white pine woods. Its 'beat' lies between 

 the sunlit tops of middle-sized pines, spruce and other trees, and their 

 bottom branches on the outer borders of the groves. The deeply 

 shaded wood-interiors it seems rather to avoid ; and it is a great 

 haunter, especially while singing, of the spindling tops of fair-sized 

 conifers. Active, restless, but very tame, it is a noticeable little bird 

 wherever it occurs, particularly in the clearly-marked costume of the 

 adult male, whose almost fleckless yellow cheeks often lead chance 

 observers to describe it as yellow-headed." (Thayer, MS.}
