I BIRDS OP ILLINOIS. 



or partially devoted to a continuation of investigations at the same 

 place. The summer of lHt>;'> was passud at Olney, Uiebland county, 

 wliL-re several birds not observed at Mount Carmel were discovered ; 

 while subsequent visits to the same place, including several trips 

 to the neit^hborinR prairies, have further increased his knowledge of 

 the bird-life of that locality. 



Without the aid furnished by the collections above referred to, 

 and the assistance kindly rendered by several gentlemen who have 

 been making a special study of the birds of their respective neigh- 

 borhoods, this catalogue would of necessity have been a purely 

 local one. Mr. H. K. Coale, of Chicago, has most generously placed 

 his note-books, full of valuable records, at the author's disposal, 

 while Mr. Chas. K. Worthen has contributed many important notes ; 

 80 that, with help from so many sources, together with various 

 local lists, and other publications' on the birds of Illinois, it has 

 been possible to prepare a tolerably full list of the birds of the 

 State at large. Much remains to be done, however, especially in 

 the western and extreme southern counties, which are certain to 

 produce important and perhaps unlooked for additions.* 



The author has endeavored to make the work as original as the 

 circumstances would allow; but on account of the limited time 

 allotted for its completion (one year), and being mainly occupied 

 with other duties, he has found it necessary to draw, to a certain 

 extent, upon previous publications. Thus, for the land-birds, many 

 of the generic diagnoses have been taken from the Ilistor;/ of North 

 American Birds,^ while for the water-birds the descriptions have 

 been copied from The Water Birds of North America.' In every 

 case, however, matter which is not original with the present work 

 is enclosed in quotation marks, and the source whence obtained 

 explicitly stated. It may further be explained that the author has 

 the permission of the publishers to make extracts, at his discretion.
