The reasons for excluding the above forms are given in detail in the 

 Hypothetical List (Appendix 2), pages 736-757. 



In addition it should be noted that the bird formerly listed as Traill's 

 Flycatcher is now recognized as a distinct subspecies, the Alder Fly- 

 catcher; the smaller Michigan Shrike is considered a new subspecies, the 

 Migrant Shrike; while the Northern Parula Warbler instead of the typical 

 Parula Warbler, is the form found here. 



The species in the present list of the birds of the state which were not 

 included in Professor Cook's list of 1893 are: 



Northern Hairy Woodpecker 

 Say's Phoebe 

 Hoyt's Horned Lark 

 Thick-billed Redwing 

 Greenland Redpoll 

 Hoary Redpoll 

 LeConte's Sparrow 

 Harris' Sparrow 

 Grinnell's Waterthrush 

 Carolina Chickadee 



The hypothetical list, forming Appendix 2 of the present volume, con- 

 tains sixty-two additional species which at one time or another have been 

 attributed to Michigan but about which there is more or less doubt. 

 Probably the larger part of them have never occurred in the state, and 

 never will occur. Some of the others, however, doubtless will be found 

 sooner or later, either as regular visitors in small numbers and to restricted 

 areas, or possibly in larger numbers at long intervals. Almost any eastern 

 American species may occur accidentally, and the same may be said of 

 western forms wdiich have a wide range in migration. Even European 

 species may appear at long intervals, not simply such as have been im- 

 ported purposely, and have escaped from captivity, but birds which nest 

 in the far north of Europe or Asia, and have strayed to Greenland, Iceland 

 or Alaska and been swept southward with the great tide of autumnal 

 migrants. Interesting as such occurrences are to the student of geograph- 

 ical distribution, the small number of individual birds concerned gives 

 the matter little or no economic importance. 



In the preparation of the following pages published material has been 

 drawn upon freely whenever it seemed advisable, but special effort has 

 also been made to get new and unpublished information, and in all cases 

 it has been the intention to eive full credit for matter so obtained. At
