BIRDS OF ELLINOIS. 



II. Characteristic Features of the Avifauna of the State. 



Qenoral Remarks. Observations in many sections of the State 

 from which we as yet have no data, and also more extended inves- 

 tigations in those sections ah-eady explored, are necessary before 

 we can have an accurate knowledge of the distribution of the spe- 

 cies within our limits. At present we know the subject merely in 

 outline, and what we assume to know is undoubtedly subject to 

 greater or less moditication — according to the species involved — in 

 the light of future information. The following tables are, therefore, 

 to be considered as provisional, and as expressing merely the 

 author's present knowledge of the subject, based in part on his own 

 explorations, but to a greater extent on the published records of 

 other observers.
