List of Birds Found in Illinois 



This list includes practically all birds to be found in Illinois, either 

 resident or migrant. Owing to the length of the State, there is naturally 

 some variation in the species observable in different sections. Birds com- 

 mon in the southern portion may rarely appear in the north, and the re- 

 verse is equally true. For example, the American Egret is a summer visitor 

 to the southern counties, but is practically unknown in the north. Again, 

 the Snowy Owl may be found in the northern district, but is seldom found 

 in the south.
