THE PASSING OF THE BIRDS. 191 



again, and the only bird to be found was 

 one phcebe ! Within half a mile of the spot, 

 however, I came upon at least three goodly 

 throngs, including scarlet tanagers (all in 

 yellow and black), black-throated blue war- 

 blers, pine warblers, olive-backed and gray- 

 cheeked thrushes, a flock of chewinks (made 

 up exclusively of adult males, so far as I 

 could discover), red-eyed vireos, one solitary 

 vireo, brown thrashers, with more redstarts, 

 a second Blackburnian, and a second black- 

 aiid-yellow. Every company had its com- 

 plement of chickadees. Of the morning's 

 forty species, thirteen were warblers; and 

 of these thirteen, four were represented by 

 one specimen each. For curiosity's sake I 

 may add that a much longer walk that after- 

 noon, through the same and other woods, 

 was utterly barren. Except for two or three 

 flocks of white-throated sparrows, there was 

 no sign whatever that the night before had 

 brought us a "flight." 



Autumnal ornithology may almost be 

 called a science by itself. Not only are birds 

 harder to find (being silent) and harder to 

 recognize in autumn than in spring, but their 

 movements are in themselves more difficult
