CONTRIBUTOKS. 



The following persons have kindl}^ furnished me with more or 

 less extended notes, or lists of the birds of the counties under 

 which their names are found. While many counties are unrep- 

 resented, most parts of the state are fairly covered, with no very 

 extensive gaps. Without the ready and willing cooperation of 

 these local observers the range of the various species would have 

 been much less accurately determined: 



AUaviakec. Dr. B. H. Bailey of Cedar Rapids allowed me to 

 examine a series of specimens in the Coe College museum, col- 

 lected in the summer of 1904, mostl}^ near Lansing.
