A List of 200 Commoner Birds 

 of Illinois 



In compiling the "List of 200 Illinois Birds" the 

 customary arrangement of families and species, fol- 

 lowed by ornithologists, has been reversed in order 

 that the more familiar birds should be at the be- 

 ginning rather than at the end of the list. 



Since the north and south extension of the state 

 is approximately 400 miles, there is considerable 

 variation in the species to be found in areas so 

 widely separated. A combined list of the birds com- 

 mon in different portions of the state will therefore 

 not be workable in every portion of the state, un-. 

 less qualifying marks of some sort are used. In 

 the following list this is accomplished by placing 

 after the names of those common only in certain 

 portions of the state, (N) indicating North, (C) 

 Central, and (S) Southern. For example, the Car- 

 dinal, although found here and there in northern 

 Illinois, can be said to be common only in central 

 and southern Illinois. It therefore appears in the 

 list as follows : — Cardinal (C) (S). 



All names on the list not followed by bracketed 

 letters represent birds that are common throughout 

 the state. It should be noted that this entire list is 

 included in the "Comprehensive Check List" to- 

 gether with many more birds more or less rare in 

 the state. The latter list is to be found on pages 23 

 to 80.
