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.
There were lawsuits, and, in 1990, the Northern subspecies of spotted owl came under the Endangered Species Act (two subspecies in other parts of the country were not affected). A sweeping federal court ruling in 1991 closed much of the Northwest woods to logging.
