identical individuals remain in the same locality 

 throughout the year, breeding and wintering in an 

 area indistinguishably variable, that is without a dif- 

 ference of approximately twenty-five miles, e. g. 

 Ruffed Grouse ; ( 2 ) those species of which the species 

 is permanently resident, but the individuals migra- 

 tory, e. g. Song Sparrow; (3) those birds which reg- 

 ularly breed during the late Spring or Summer but 

 do not remain, except irregularly through the Winter 

 months, e. g. Baltimore Oriole; (4) those birds which 

 do not breed or remain through the Summer months 

 but regularly arrive in the Fall and remain through 

 the Winter, e. g. Junco; (5). those birds which, after, 

 or more rarely, just before, breeding stray north- 

 ward, but do not breed or remain regularly through 

 the Summer months, e. g. Egret; (6) those birds 

 which are driven South in Winter by storms or lack 

 of food supply and irregularly visit the specified local- 

 ity. At times birds of this class may be common but 

 they are always irregularly so, e. g. Evening Gros- 

 beak; (7) those birds which remain regularly neither 

 during the Summer or Winter but do regularly mi- 

 grate through in the Spring and Fall, e. g. Yellow- 

 bellied Sapsucker. 



Now I will attempt to name my classes. For class 

 1 I suggest the term individual resident. This will 

 undoubtedly be criticized as being uncommon, un- 

 known, and too long, but certainly it is at least clear 

 to anyone what is meant. Class 2 I should merely 

 term resident. I do not think this term can be com- 

 mented on as being out of place here. Certainly it 

 is perfectly correct in this case, meaning exactly what 

 it means as a word — resident — not migratory.
