THE WARBLERS. 175 
relation to the Vireonide, that the Myiodiocte, of which the 
green black-capped warbler is a member, do to the Musci- 
capide, or Flycatchers. The blue-winged yellow warbler is 
one of those that spend the summer with us; but though it 
is quite abundant during that season, I have never been for- 
tunate enough to discover its nest, although I have repeat- 
edly seen the young just fledged. It arrives about the tenth 
of May, and takes up its abode in the closest thickets and 
underbrush. Its note is very forcible and characteristic ; 
‘once heard, it will always be remembered. It is a rapid 
chirrup, nearly undescribable in words, though the follow- 
ing syllables bear some resemblance to it, chaachich-k'-a-re- 
r'r'r'r!, uttered very quickly. It leaves in August. 
The Mourning Warbler (Geothlypis Philadelphia) is a 
very rare species, scarcely less so than the Connecticut war- 
bler. It arrives late in spring, about the twenty-fifth of 
May, or first of J une; of its notes and habits I know noth- 
ing, having only seen one or two individuals. This and the 
Connecticut warbler have been considered by some orni- 
thologists to be identical, but they are undoubtedly perfectly 
istinct. 
One of the rarest of all is the Cape May Warbler (D. 
tigrina). Like the preceding, it is a late comer, arriving 
generally toward the end of May, and staying a very brief 
period. In the autumn it passes here, on its southward 
course, about the twentieth of September. Of its notes I 
know nothing, except that it has a faint chirp like all sthe 
other warblers; and of its habits, nothing worthy of par- 
ticular notice, except that it shows a preference to cedar, and 
other evergreen trees. 
The Green Black-capped Warbler (Mzyiodioctes pusillus) 
's one of those belonging to the section or genus intermediate 
between the warblers and flycatchers. It is very much 
nearer the former, however, than the latter; and itis a matter 
of some little surprise, how it could have been ranked odie 
flycatcher. Audubon says that it passes through the Middle
