script coloration of some species in autumn, and the fact that 
many kinds, even in spring, can only be identified by most nat- 
uralists upon a close examination, to obtain which it is nec- 
essary to shoot the birds, when of course their habits can no 
longer be studied. It is for these reasons that it is important 
to know the minor notes of various species, for by these one 
can often easily distinguish two species otherwise closely alike, 
especially if such notes are associated with other more marked 
characteristics. Thus one can in this way always distinguish 
“Yellow-rumps” at a great distance, for though their ordinary 
“chuck” is very much. like that of the “Black-polls” (who are 
here in autumn at the same time), yet their manner of flight is 
different. 
(da). The ordinary notes of the Nashville Warblers are a 
simple chip, a loud chink, and a peculiar alarm-note (?) entirely 
characteristic, which is hardly, I think, as Wilson says, much 
like ‘the breaking of small dry twigs, or the striking of small 
pebbles of different sizes smartly against each other for six or 
seven times,” though it may be recognized by that description. 
It is “loud enough,” as that author says, ‘‘to be heard at the 
distance of thirty or forty yards.” 
Their song is simple but pretty, more resembling that of the 
common Summer Yellow-bird (D. estiva) or Chestnut-sided 
Warbler than that.of any other species. It may be represented 
by the syllables wee'-see-wee'-see, wit'-a-wit'-a-wit'. 
(D) cetata. Orange-crowned Warbler. 
(This species was reported from Maine by Audubon, and a 
specimen was shot by Mr. Allen at Springfield on the fifteenth 
of May, 1863.) 
(a). Essentially like the Nashville Warbler (C); but with 
the slate of the latter’'wanting, the chestnut supplied by orange- 
brown, and the yellow green-tinged. 
(b). Nest and eggs probably like those of the last species. 
(c). The Orange-crowned Warblers are unknown to me 
personally, but probably there is little or no difference between 
their habits and those of the Nashville Warblers, to whom they
