162 BIRDS OF ILLIXOIS, 



"A very young bird (22,619, Fort Simpson, August 10) is very 

 dififerent from the adult in coloration. The upper parts are fuligi- 

 nous black, each feather with a broad tenuinal bar of pale ochra- 

 ceous, wing-coverts tipped with the same, forming two distinct 

 bands ; streaks below as in the adult, but broader and less sharply 

 defined." {Hist N. Am. B.) 



The summer home of the Water-thrush is in the more northern 

 portions of the continent, its breeding range embracing the whole 

 of arctic and subarctic America, from the western portions of Alaska 

 to the region about Hudson's Bay, and southward to the northern 

 border of the United States. In Illinois the species is known as a 

 migrant, passing slowly through in spring and fall, though in the 

 extreme southern portion a few pass the winter, especially if the 

 season be mild. At Mount Carmel it sometimes became common in 

 the latter half of August, and in spring usually remained until 

 after the Louisiana Water-thrush had begun nesting.

 dusky stripe along upper edge of the auriculars. Lores crossed by a distinct streak of 

 black. Centre of the abdomen immaculate; lower tail-coverts with central streaks of 

 grayish dusky; lining of the wing smoky gray. Bill brownish black, the mandible grow-

The plumage of the tj'pe specimen of this bird is in all respects, 

 so far as I can see, quite identical with that of ordinary darker 

 plumaged specimens of >S'. noveboracensis, such as occur more com- 

 monly west of the Alleghanies, except that the superciliary stripe 

 does not extend so far back and the streaks on the breast are 

 broader; the former character may be merely apparent, however, 

 and owing to the "make-up" of the skin. 



An adult male collected by G. H. Ragsdale, at Gainesville, Texas, 

 Sept. 11, 1880, and consequently in autumnal plumage, differs con- 

 spicuously from fall specimens of typical noveboracensis in the much
