142 BIRDS OF MAINE. 



include 39 species. The accidental or casual visitants and strag- 

 glers include 65 species, while the remaining 2 species formerly 

 occurred within our limits but are now extinct in the state. 



In the synopsis given below I have endeavored, with the evidence 

 at hand, to place each species under that heading which seemed to 

 most nearly represent its status in the state, while by appropriate 

 markings I have designated those which might be included under 

 other headings by another person. Persons disagreeing with my 

 grouping of any species will find in the text of the work, under that 

 species, data from which they are at liberty to draw their own 

 conclusions. 



PERMANENT RESIDENTS. 



The majority of the 26 species given here are resident, 

 but those designated by an asterisk are chiefly or entirely 

 entirely confined to the Canadian fauna during the breeding season. 

 It is highly probable that in the case of some species the same 

 individual birds do not remain in one locality throughout the year, but 

 birds which summer here go south for the winter, and are replaced 

 during that season by individuals which have summered north of 

 our limits.

SUMMER RESIDENTS. 



The species which occur in greatest numbers as summer residents, 

 include 114 birds, some of which might have been equally well 

 included under one of the other headings. Those designated by an 

 asterisk have been known to occur in winter, though usually rare 

 at this season.
