 more extensive than that of most Dendroecce, and includes 

 Eastern North America from Labrador at least to Georgia.

 ous during its migrations, many breed throughout New 

 England.

Dendrceca striata Baird. Black-poll Warbler. Abun- 

 dant spring and autumn migrant ; some breeding in more 

 northern sections. (TJmbagog Lakes, Ferr.,p. 12; Calais, 

 Me., Hoardm., p. 125.) A species whose northern range 

 extends far into arctic America, and the one which passes 

 almost latest of all through the United States on its way 

 north in spring.

Dendrceca cestiva Baird. Golden Warbler. Summer 

 Yellow-bird. Abundant summer resident everywhere. A 

 certain Sylvia trochilus Lath., the "yellow" or "willow" 

 wren, which is given by some writef^ (Peab., p. 312, 

 Liiisl. , p. 257) , can hardly be else than the autumnal or im- 

 mature plumage of this species ; which has also furnished 

 the basis for the Sylvia Childrenii, and perhaps, too, the 

 tS. Rathbonice of Audubon's works. The " Sylvia flava 

 Lath.," of Linsley, p. 258, cannot be identified. It may 

 be either the Summer Warbler, or D. palmarum.

Dendroeca maculosa Baird. Black and Yellow Warbler. 

 Chiefly spring and autumn migrant ; common. But it 

 breeds in Maine, and apparently not rarely (Calais, Me., 

 Verr., p. 234). It goes very far north in the interior of 

 North America.
