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 types and occur well within its limits. 

 However they may all be regarded as fairly distinctive. 



The Alleghanian Fauna is characterized by 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, House 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 faunae 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 southwesterly direction across the State. 

 Part of this is wrong in view of information of which I am now possessed. 



We may safely assign to the Canadian Fauna the entire granite-ridged, 

 spruce-covered sections of the coast save a few local Hudsonian infusions. 

 The Laurentine 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. 



In a recent article regarding the "Sharp-tailed Finches of Maine" Mr. A 

 H. Norton speaks of the habitat of the Acadian Sharp-tail as follows : "North 

 of Scarboro, beginning with Cape Elizabeth, its eastern boundary, the coast 

 presents an uneven or hilly face of rocks, indented with numerous coves 

 and bays, studded with dry ledgy islands. Between the hills are innumerable 

 arms of the sea often extending as "tide rivers" or fjords several miles inland, 

 bordered by narrow swales. Coincident with these features is the low spruce 

 woods, so conspicuous a feature of the Maine coast, so characteristic of the 

 scanty soiled granite ridges, and the fog drenched coast of the northeast. 

 Very different in appearance are the broad marshes of Scarboro and western 

 Maine, backed by soil-clad verdant slopes, with pine and hard woods replacing 

 the spruce." (Cf. Norton, Proc. Port. Soc. Nat. Hist, Vol. 2. pp. 100-101). 



In my judgment he has here outlined the dividing line between the two 

 faunae, and the Canadian thus extends along the coast to Cape Elizabeth. A 

 few miles back in the interior these Canadian features cease, and we will
