Bill nearly concealed by projecting plumes ; eyes large. Entire plumage white, frequently with a few spots, or imperfect 
bands, only on the upper parts, dark brown, and on the under parts, with a few irregular and imperfect bars of the same ; quills 
and tail with a few spots or traces of bands of the same dark brown. The prevalence of the dark brown color varies much in 
different specimens ; frequently both upper and under parts are very distinctly handed transversely, and sometimes this color 
predominates on the back. Plumage of the legs and toes, pure snowy white ; bill and claws dark horn color ; irides yellow. 
Total length, 24 to 27 inches ; wing 16 to 17 ; tail 10 inches. 
Hab. —Northern regions of both continents, migrating southward in the winter. Resident in Canada, (Dr. A. Hall,) 
Greenland, (Holboll,) South Carolina, Kentucky, (Audubon,) Bermuda, (Jardinc.) Spec, in Nat. Mus. Washington, and 
Mus. Acad. Philadelphia. 
The large size aud white plumage of this owl render it a conspicuous species when met with 
in the woods, or during its winter wanderings, and also when prepared for the museum. It is 
an abundant species in the northern regions, and has been observed at the highest northern 
latitude yet attained by voyagers. In the winter it migrates over nearly the whole of Europe 
and North America, and is frequently to be met with in the Northern and Middle United States, 
varying greatly in numbers in different years. According to Dr. A. Hall, of Montreal, Canada, 
this fine species is resident in that province, making its nest on the ground. 
This bird presents considerable variety of plumage, according to the greater or less number 
of the dark transverse bands which are present, to more or less extent, in the majority of 
specimens, sometimes prevailing on the upper parts of the body. Frequently, however, these 
bands are so few and indistinct that the bird is almost pure and snowy white. Audubon’s plate 
represents this owl unusually dark; Wilson’s figure is, in plumage, more usually met with, 
and is more truthful.
