OWL, HAWK. 
Srrrx ai Lin. 
An individual of this species was captured in 
March, 1830, off the southern coast of England, 
and another specimen is recorded as having been 
taken in 1847, near the Tatton Station, on the 
Bristol and Exeter Railway. It is a common 
species throughout the fur countries of America, 
from Hudson’s Bay to the Pacific. 
The Hawk Owl, from the formation of its head 
and feet and the length of its tail, appears to be a 
connecting link between the Hawk and the Owl. 
Contrary to the general habits of Owls, it flies and 
pursues its prey by day. 
In the summer season it feeds principally on 
mice and insects, but in the snow-clad regions 
which it frequents in winter, neither of these 
can be procured, and it then preys mostly on Ptar- 
migan. Its nest, which it builds on trees, is 
ecmposed of sticks, grass, and feathers, and it lays 
two white egos.
