74 BIRDS OF PREY. 
2 eggs in the month of May. It feeds on mice and beetles. 
It probably inhabits all the forests of the fur countries from 
Great Slave Lake to the United States. On the banks of the 
Saskatchewan it is so common that its voice is heard almost 
every night by the traveller wherever he may select his camp. 
It inhabits the woods along the streams of the Rocky Moun- 
tains down to the Oregon, and betrays but little suspicion 
when approached. 
Richardson’s Owl is usually a rare winter visitor to the Maritime 
Provinces; but Mr. C. B. Cory found it common and breeding on 
the Magdalene Islands, and a few examples have been taken in 
New Brunswick in summer. 
It is common on the north shore of the Gulf of St. Lawrence, 
though rare near the city of Quebec; it occurs sparingly in winter 
along the northern border of New England and in southern Onta- 
rio, and occasionally straggles to Massachusetts and Connecticut. 
Thompson reports it common in Manitoba.
