 meadows and marshes. In such places I have found them also during 

 the winter at times. 



It probably breeds in the interior of the Province. 



Genus SYKNIUM. 



152. Barred Owl.

A few of these birds generally occur in the southern parts of the 

 Province every autumn, but I have not heard of its being observed at 

 any other season. Probably resident in the interior.

 so from Illinois northward.
