331. Wilsonia canadensis (Ivinn.). Canadian War- 

 bler. 



A common spring and fall migrant, and less common summer 

 resident within the Canadian faunal area. It is common in 

 summer in the White Mountain region along the forest brooks 

 grown up with spruce, balsam and a tangle of hobble bush, 

 where the dampness keeps the ground deeply carpeted with 

 moss ; and in similar situations it occurs locally throughout the 

 state, though in central and southeastern New Hampshire it is 

 far from common. Mr. G. H. Thayer finds it in considerable 

 numbers in the deep, well-watered woods about Mt. Monadnock. 

 The greatest altitude at which I have observed breeding birds 

 is 3,360 feet in the Carter Notch, where on June 21, 1900, a bird 

 was heard singing by the lakes. 

 Dates : May 13 to September 13. 



232. Setopliaga niticilla (Ivinn.). American Red- 

 start. 



A common migrant and summer resident of the Transition 

 and sub-Canadian woods throughout the state. On the White 

 Mountains it is fairly common in the deciduous and mixed 

 woods up to about 3,000 feet, and appears to be commoner in 

 such localities than about the village shade trees and the or- 

 chards. The Redstart is the " Paul Pry " of the woods, and in 

 the northern forests I have usually found it to be about the first 

 bird on the scene whenever a passing Blue Jay or other intrud- 

 er appears. 



Dates : May 4 to September 21. 



2.33. Anthus pensilvanicus (Ivath.). American Pipit. 



A migrant, uncommon in spring but more numerous in fall. 

 Inland, the bird appears to be rare in spring, though on the 

 coast it is of regular occurrence. Messrs. Goodhue and Dear- 

 born have noted it in spring in Belknap and Merrimack Coun- 

 ties. In the White Mountain valleys, I have usually observed 

 it in small flocks after the 15th of September. 



Dates: April to May 10; September 15 to November.
