SUMMER BIRDS. 
taken at the Umbagog Lakes in Maine, as to leave no question as 
to its identity. 
Dendrceca Pennsylvanica (L.) Baird. Chestnut-sided Warbler. 
Perhaps the most common warbler and, excepting the Summer 
Yellow Warbler, the only one ever noticed about cultivated land. 
Though apparently not penetrating high in the forests it was, never- 
theless, found in the woods, but principally about their borders and 
in clearing's. 
A nest found June 8, 1 880, amidst briers and shrubbery at the edge 
of woods, contained four young several days old. Four nests were 
taken by Mr. Pearsall between June 10 and 13, all, except one on the 
latter date with three, containing four fresh eggs. “One taken June 
12, was commenced May 31.” With one exception these nests were 
built in the forked stem of a brier. The excepted instance was one in 
which a “ cluster of young beech sprouts in an open hillside pasture” 
had been utilized. 
Dcudroeca striata (P'orst.) Baird. Black-poll Warbler. 
This northerly breeding species was found to be common, in fact, 
the most common warbler, about the summit of Slide Mountain, 
though lower than a few hundred feet from this point it was not met 
with. In June of three successive years (12, 1880; 1 5 — 1 6 , 1881; 
and 25-26, 1882) it was there present, and, on the last occasion 
especially its characteristic notes more frequently, perhaps, than those 
of any other bird, broke the silence of that lonely spot. That it 
is there a regular summer resident can hardly be doubted. Though 
from the exceeding lateness of the spring of 1882 its presence late in 
June of that year might well have been exceptional, the balance of 
the evidence above given weighs strongly against the probability of 
its having so been. As the Black-poll Warbler is, however, our 
most dilatory spring migrant, and its southernmost breeding limit 
has been supposed to fall far short of southern New York, some col- 
lated data bearing on the duration of its vernal migration and the 
time of its nesting period will here be apposite. 
Pertinent to the subject are the following latest dates of its depart- 
ure on the spring migration from points of the Middle and Eastern 
States: Washington, D. C., June 1 (Coues and Prentiss); New Jer- 
sey, June 5 (Gentry) ; my own record carries the time of its presence 
near New York City to June 1 1 (1882 ; a female), but this instance of 
its stay is exceptional, the record of other years not extending be- 
yond June 4; Hudson Highlands, May 29 (Mearns) ; Connecticut, 
June 2, (Merriam = Sage); Massachusetts, June 10 (Brewer);
