Maynard.] 366 [October 18? 



similar to that of the Redstart, to which it bears a striking resem- 

 blance, with the exception that it is given with less energy. This 

 species seems to be confined during the breeding season to the region 

 just north of the White Mountains range. 



This species, together with Geothlypis Philadelphia and Helminthoph- 

 aga p>eregrina, seems to pursue a very eccentric course during the mi- 

 grations. Avoiding the eastern and middle States, the majority pass 

 along the borders of the Great Lakes, through Ohio, southern Illinois 

 (Ridg way x ) , down the Mississippi Valley, across into Texas, and so 

 on into Mexico and Central America where they winter. Returning 

 in spring they (at least D. castaned) pursue a more southern route, 

 keeping along the coast as far as the New England States, where 

 they ascend the Connecticut Valley, generally avoiding eastern Mas- 

 sachusetts. 



29. Dendroeea striata Baird. Black-polled Warbler. 



Not common at Umbagog, Hamilton \ (Mcllwraith), or at Nor- 

 way (Verrill) during the migrations. Breeds at Quebec (Couper). 

 They disappeared from Upton about June 5th. This species breeds 

 very far north, probably in Labrador. Some few winter in the West 

 Indies, but the greater part pass into South America. I have never 

 seen it in Florida or on the Keys. 



30. Dendroeea pinus Baird. Pine Warbler. 



Common during the migrations at Hamilton (Mcll wraith). Prob- 

 ably occurs rarely in the southern sections of Oxford county, but this 

 is far north of its usual range. This species breeds from Florida to 

 Massachusetts. They winter in great numbers in the pine woods of 

 the main-land of Florida. 



31. Dendroeea Pennsylvaniea Baird. Chestnut-sided War- 

 bler. 



Common at Hamilton ( Mcllwraith ) during the summer. 

 Bather common at Norway (Verrill), but not very abundant at Um- 

 bagog or at Quebec (Couper). Breeds at all the above mentioned 

 localities; it may, however, find its northern limit somewhere about 

 Quebec. This species mainly winters in Mexico and Central Amer- 

 ica. They, however, follow the coast during both migrations. 



32. Dendroeea sestiva Baird. Yellow Warbler. 



Given as abundant by Mcllwraith, at Hamilton, Couper at Que- 

 bec, and Verrill at Norway. Although this bird is known to have 



ilnMss., June, 1870.
