SUMMER BIRDS. 



taken at the Umbagog Lakes in Maine, as to leave no question as 

 to its identity. 



Deudropca Peiiusylvauica (L.) Baird. Chestnut-sided Warbler. 



Perhaps the most common warbler and, excepting the Summer 

 Yellow \\'arbler, 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 clearings. 



A nest found June 8, 1880, 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. 



Deiidropca striata (Forst.) 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; i5-i6. 1881 ; 

 and 26-26, 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 1S82 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 W^arbler 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, 13. C, June i (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);
