XXXIII. — Catalogue of the Birds ascertained to occur in 



Illinois.

The following catalogue of the birds of Illinois embraces 

 only species which have been actually observed by the author 

 within the limits of the state, and those otherwise included 

 by reason of reliable authority for their capture, in which 

 case the fact and reference are noted. 



Though sixty-five species not previously accredited to the 

 avi-fauna of the state, in any published catalogue or notice, 

 are given here, the lists by Mr. Robert Keunicott, Mr. Henry 

 Pratten and Dr. R. B. Holder, published in various numbers 

 of the "Transactions of the Illinois State Agricultural So- 

 ciety," furnish a few which I could not give on my own 

 responsibility ; while for the privilege of including several 

 species of water-fowl found about the southern end of Lake 

 Michigan, I am indebted to Dr. J. W. Velie, of the Chicago 

 Academy of Sciences, who has kindly furnished me much 

 information concerning the birds of the northern portion. 



The various local and general lists of the birds of Illinois, 

 which have from time to time been published, are severally 

 noticed and criticised at the close of this work, in an ap- 

 pendix specially devoted to a review of the bibliography of 

 the ornithology of the state. 



The range within the state's limits, of each species, is 

 indicated approximately, or according to our present knowl- 

 edge of their habitat. When no particular section is men- 

 tioned, it is to be understood that the distribution is general ; 

 and if any doubt exists as to the limitation of the range, or 

 the question of the breeding, of any species, care is taken to 

 call particular attention to it. 



The asterisk before the number indicates that the species 

 breeds within the state.
