GREAT GRAY OWLS are residents of the northern half 

 of Canada and Alaska. During severe winters they some- 

 times migrate south to our northern borders, but their 

 appearance is very erratic. Their plumage is very loose and 

 fluffy, the long feathers giving them an appearance of great 

 size that does not in reality exist. The head is very full- 

 feathered, the facial disc being unusually large. The eyes, 

 however, are small and yellow, while those of the Barred 

 Owl, the only species with which this can be confused, are 

 large and dark brown or blue-black. 



RICHARDSON'S OWLS are a boreal species that casu- 

 ally occurs along our northern border during winter. They 

 breed throughout Canada, but most abundantly in the 

 northern half and in Alaska. They are so nocturnal in 

 habits and so indifferent to the presence of man that, if 

 found during daylight, they can often be taken in the hands. 

 They resemble the next, more common, species, but are 

 larger and grayer; the top of the head is spotted and the 

 breast barred, while the smaUer species is streaked.
