362 WOOD WARBLERS. 



throat and breast more or less mixed with yellowish. Im. — Similar to the 

 ? , but with more yellow on the throat, the black sometimes being almost 

 entirely hidden or wanting. L., 5-10 ; W., 2-46 ; T., 1-99 ; B. from N., -25. 



Remarks. — The bright yellow cheeks of this species, in connection with 

 the large amount of white in the tail, will serve to distinguish it in any 

 plumage. 



Range. — Eastern North America; breeds from northern Illinois and Con- 

 necticut nortliward to Hudson Bay and southward along the Alleghanies to 

 South Carolina ; winters in the tropics. 



Washington, very common T. V., Apl. 25 to May 28 ; Aug. 28 to Oct. 21. 

 Sing Sing, connnon T. V., Apl. 30 to June 3 ; Sept. 1 to Oct. 2G ; a few breed. 

 Cambridge, very common S. E., May 1 to Oct. 15. 



Nest.^ of small twigs and moss, lined with rootlets, fine grasses, and ten- 

 drils, in coniferous trees, fifteen to fifty feet from the ground. Eggs^ four, 

 white, distinctly and obscurely spotted and speckled with olive-brown or 

 umber, chiefly at the larger end, -65 x -46. 



When migrating this species joins the ranks of the Warbler army 

 and visits wooded land of almost any kind. When nesting it prefers 

 coniferous forests, where it is a dweller among the tree tops. 



While resembling its congeners in general habits, the song of the 

 Black-throated Green is so unlike their generally humble ditties that 

 the bird seems possessed of more character than they impress us with 

 having. Mr. Burroughs graphically represents its notes by straight 



lines: V ; a novel method of musical annotation, but 



which nevertheless will aid one in recognizing the bird's song. There 

 is a quality about it like the droning of bees; it seems to voice the 

 restf ulness of a midsummer day. 



Townsend's Warbler {668. Dendroica to^vnsendi)., a species of western 

 North America, has been once recorded from Pennsylvania. 



670. Dendroica kirtlandi Baird. Kirtlakd's Warbler. Ad. — 



Head bluish gray, sometimes spotted with black; lores and sides of the throat

 tail-feathers with white patches on their inner webs at the tips ; under parts 

 pale yellow; sides streaked and spotted with black. L., 5-75 ; W., 2-75 ; T., 

 2-30; B. from N., -32. 



Range.— Wxs^roXa^ through southeastern United States and Mississippi 

 Valley (South Carolina, Virginia, Missouri, Ohio, Michigan, Wisconsin, Hli- 

 nois, Minnesota) ; summer home unknown ; winters in the Bahamas. 



Washington, casual T. V., one record, Sept. 26, 1887. 



The dozen or more specimens of this rare Warbler which have been 

 taken in the United States were captured in late April and May and 

 late September and October. Six specimens have been recorded from 

 Michigan, all taken in May, and it is possible these birds were en route 

 to a nesting ground in the Hudson Bay region. It is not uncommon 

 in winter in the Bahamas.
