ill if species has considerable affinity to the flycatchers 
habits. It i.s chiefly confined to the woods, and 
there, to the tops of the tallest trees, where it is 
w*"''ed skipping from branch to branch, in pursuit of 
insects. Its note is a single screep, scarcely 
Co from below. It arrives in Pennsylvania about 
lii„)~bth of April, and is first seen on the tops of the 
the maples, darting about among the blossoms. As 
j^j'''oods thicken u'ith leaves, it may be found pretty 
being none of the least numerous of our 
in birds. It is, hoAAmver, most partial to woods 
‘e immediate neighbourhood of creeks, swamps, or 
probably from the greater number of its 
pr^J'frte insects freiiuenting such places. It is also 
tu'Jv.S^tterally diffused over the United States, baying 
met with it in most quarters of the Union; 
q?.§h its nest has hitherto defied all my researches. 
,ms bird may be considered as occupying an inter- 
bler ® station between the flycatchers and the war- 
having the manners of the former, and the bill, 
of the latter. The nice gradations by Avhich 
(ie,, ''® passes from one species to another, even in this 
liijllj ^ment of the great chain of beings, will for ever 
C ® the artificial rules and systems of man. And 
for^ilY'^fh every fresh discovery must impress more 
liifij on the mind of the observing naturalist. These 
ij, leave us early in September. 
® black-poll warbler is five and a half inches long.
