able localities more especially toward the southwestern portion of 

 the peninsula, and the region about Lake Mistassini: Saw- whet 

 Owl, Northern Hairy Woodpecker, Olive-sided Flycatcher, Yellow- 

 bellied Flycatcher, Purple Finch, American Red Crossbill, Magnolia 

 Warbler, Black-throated Green Warbler, Canadian Warbler, Black- 

 capped Chickadee, Hermit Thrush. 



In a very general way, the latitude of Hamilton Inlet may probably 

 be taken as the northern limit for the Canadian species of birds, 

 though a few such as the Rusty Grackle and Pine Grosbeak extend 

 their ranges much beyond this. On the other hand, most of the 

 species that are strictly limited to the Canadian zone do not come 

 quite so far as this. 



The intermingling of these species of the Hudsonian and Canadian 

 zones was well shown by our experience at St. Lewis Inlet near Battle 

 Harbor. Here we found Redpolls, White-crowned Sparrows, Lin- 

 coln's Sparrows, Black-poll, Wilson's, and Tennessee Warblers, and 

 Alice's Thrush, as well as White-throated Sparrows, and Hermit 

 Thrushes. The strong-flying, wide-ranging American Robin was also 

 a common bird here. 



In addition to these land birds that are characteristic breeding species, 

 there are others that occur occasionally as stragglers in the southern 

 part of Labrador, having come from still farther south, and whose 

 general northern range is limited by the Transition zone. Such are 

 the Marsh Hawk, Belted Kingfisher, Northern Flicker, Nighthawk, 

 American Crow, Song Sparrow, and Cedar-bird. The presence of 

 these birds, however, is more or less irregular or accidental. 



Migration. 



The coastwise migration of many of the waterfowl of Labrador 

 is of interest. Dr. Grenfell has described the "ceaseless stream 

 of birds " passing south during the last of October near Battle Harbor. 

 "Long solemn streams of eider ducks, leisurely, and more graceful 

 clouds of gulls, more bustling companies of auks and guillemots, and 

 all the while fringes of fussy murrelets" (Dovekies). These birds 

 appear to follow along the coast to the southern shores of Labrador 

 and the Gulf of St. Lawrence, or even farther, to the Nova Scotia 

 waters. The amount of ice along shore determines largely whether 

 the ducks, gulls, guillemots, and auks stay during the winter in south-
