The snowy owl and many other types of owls are endangered. Most owls are endangered except for a few. There are no species of endangered owl in North America. Below is the official status for NA owls, by species. Although some local populations of these species are in some trouble (i.e., northern spotted owl) by no means are most owl species endangered.
Snowy owls have been known to hunt fish (when they can find them), squirrels, rabbits, rats, birds and even large mammals such as gophers and foxes. Like other species of large bird, the snowy owl is known to swallow it's food whole and then regurgitate the bones in the form of a pellet up to 24 hours after feeding.In order to sustain itself, the snowy owl must eat around 5 lemmings or mice every day which is nearly 2,000 in one year.he snowy owl is one of the largest species of owl in the world, with the average adult snowy owl growing to about 65cm tall with a wingspan of around 140cm. Snowy owls however can be smaller than this, and can even grow to more than 75cm in height.
