BIRDS OF MAINE. 149 



Canada Porcupine, Northern Hare, Red Squirrel, and Jumping 

 Mouse are characteristic mammals. A partial list of the birds is 

 found in the table below. 



BIKDS OF THE CANADIAN FAUNA. 



Black Guillemot, American Herring Gull, Leach's Petrel, Red- 

 breasted Merganser, American Goshawk, Olive-sided Fly- 

 catcher, Yellow-bellied Flj'catcher, Canada Jay, Northern 

 Raven, Rusty Grackle, Pine Siskin, Acadian Sharp-tailed 

 Sparrow, White-throated Sparrow, Slate-colored Junco, Red- 

 ^ breasted Nuthatch, Olive-backed Thrush, Golden-crowned Kinglet, 

 Water-Thrush, Brown Creeper, Winter Wren, Myrtle Warbler, 

 Black-throated Blue Warbler, Bay-breasted Warbler, Black Poll 

 Warbler, Wilson's Warbler, Magnolia Warbler, Alder Flycatcher. 



The above is merely a partial list of the birds which distinguish 

 the limits of this fauna. Some of these occur in slight numbers in 

 the Alleghanian while others are extreme Canadian tj'pes and occur 

 well within its limits. However they natxy all be regarded as fairly 

 distinctive. 



The Alleghanian F'auna is characterized b}' such trees as the 

 pine and oak. The birds are given below. 



Least Bittern, Green Heron, Mourning Dove, Meadow Lark, 

 Yellow-billed Cuckoo, Field Sparrow, Sharp-tailed Sparrow, Wood 

 Thrush, Towhee, Brown Thrasher, Llouse Wren, Bob-white. 



The birds cited above may be considered fairly typical of their 

 respective faunae, and the prevalence of the species of one over 

 those of the other will settle to which fauna a given locality belongs. 



Previous observers have assigned the dividing line between our 

 fauni>5 to a somewhat indefinite locality near Mount Desert Island. 

 Beginning here, the Alleghanian Fauna has been stated to include 

 the territory south of the line of mountains which run in a south- 

 westerly direction across the state. Part of this is wrong in view 

 of information of which I am now possessed. 



We ma}^ safely assign to the Canadian Fauna the entire granite- 

 ridged, spruce-covered sections of the coast. The Laureutian Hills 

 with their outspurs present features which are in strong contrast to 

 those of the southwestern part of the state. The southern limit of 

 growth of the low, stunted spruces of the coast is coincident with 

 the distribution of the majority of Canadian birds, although many 

 are not found quite so far southwards.
