The White-eyed Vireo is a very common summer resident in 

 southern Illinois, but of only casual occurrence in northern Illinois, 

 and a rare summer resident in southern Wisconsin. 



Mr. E. W. Nelson gives it as a rather rare summer resident in 

 northeastern Illinois. Mr. Frank M. Woodruflf considers it a rare 

 bird in the " Chicago Area " and records a specimen taken by Mr. 

 B. T. Gault at Glen Ellyn, May 24, 1898. Prof. Ridgway found 

 it "an abundant species in suitable localities" in southern Illinois, 

 and Mr. John F. Ferry found it common in the vicinity of Henry, 

 Marshall Co., Illinois. It has been found breeding at Fairbury, 

 Livingston Co., Illinois. (Mundt, Orn. and Ool., Vol. VIII, 1883, 

 p. 10.) And there is an egg in the Thomas H. Douglass collection at 

 Waukegan, Lake Co., Illinois, labeled as having been collected by 

 him in that locality. May 13, 1875.
