Migration. — A few large autumnal flights of this species have been 

 observed. One occurred through the interior of British Columbia 

 during the winter of 1898-99. During the winter of 1904 Richardson's 

 owls were fairly common in the Red River Valley of North Dakota. 

 For the first time in many j^ears a heavy flight was recorded at Sault

 being observed on March 4, 1923. In this same season a large flight 

 was witnessed at Ottawa, Ontario.
