The Great Gray Owl is of rare occurrence in Illinois. Kennicott 

 (1854) records it from Cook County, and Mr. E. W. Nelson (Birds N. 

 E. Illinois, p. 1 16) gives it as "a very rare winter visitant." 



In Wisconsin Dr. Hoy gives it as having been taken near Racine 

 in 1848. Kumlien and Hollister (Birds of Wisconsin, p. 70) write: 

 : ' Two specimens were sent Thure Kumlien from Bark River woods, 

 Jefferson County, about the same time (1848). We have received 

 two specimens from Iron River, taken in November, 1891. * * * * 

 If we could trust reports from hunters and residents in the Lake 

 Superior region, we would say that it is not rare in winter in that 

 section, particularly during severe weather." King (Geology of 

 Wisconsin, 1883, P- 5^o) gives it as a winter resident.

Richardson's Owl must be considered a rare bird within our limits.
