66^ THE BIRDS OF MAINE 



find ourselves in the midst of Alleghanian sxirroundings. These latter extend 

 eastward in the interior into Lincoln County, where the two regions seem- 

 ingly meet, as is evidenced by the pine trees and spruces being about equal 

 in numbers. To the northward the Alleghanian surroundings predominate 

 through much of Androscoggin, Cumberland, Kennebec, Lincoln and Oxford. 

 Save for the local Hudsonian areas previously mentioned all of the region 

 to the eastward of the Penobscot River, together with that north from the 

 northern parts of the five before-mentioned counties is Canadian in character. 

 Of this there can be no doubt. We may therefore say that Aroostook, Frank- 

 lin, Hancock, Knox, Penobscot, Piscataquis, Somerset, Waldo and Washington 

 Counties are Canadian save the few local Hudsonian and Alleghanian areas 

 mentioned elsewhere. A narrow Canadian strip extends along the coast 

 through Lincoln and Sagadahoc into Cumberland. The northern parts of 

 Androscoggin, Kennebec and Oxford also extreme western Oxford and Cum- 

 berland may be also included in this fauna. 



ALLEGHANIAN FAUNA. 



The Alleghanian includes all of York County and such parts of Andros- 

 coggin, Cumberland, Kennebec, Lincoln, Oxford and Sagadahoc as have not 

 been previously designated as Canadian. The local area near Bangor inhab- 

 ited by the Short-billed Marsh Wren is Alleghanian. 



Many local isolated areas of one fauna with another will yet be located 

 by further research. These local areas will ultimately be mapped out with a 

 precision not now possible. 



The faunal areas as determined herewith are largely the result of my own 

 personal field observations of recent years, but where the observations of 

 others are used as a basis of conclusions due credit has been given.
