dark marks as it advances in age. The young are also said 
to be at first of a brown colour, afterwards they mostly re- 
semble the female, but do not attain their full plumage for 
several years. 
The only parts of this kingdom where the Snowy Owl is 
known as a native, are some of the Shetland Isles. In the 
Isle of Unst Mr. Bullock procured the specimen now in the 
British Museum ; he also met with it in the Isles of North 
Ronaldsha, Westra and Yell ; in the latter it is supposed to , 
breed, and it resides there all the year. 
It commonly frequents rabbit-warrens and exposed places, 
and seeks its prey during the day-time, which consists prin-i 
cipally of rabbits ; " its flight is said to be more light and 
buoyant than any of the Hawks, but not so much so as th© 
common Barn Owl."
