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.
The snowy owl (Bubo scandiacus) was regarded as the only member of the genus Nyctea, classified first by Carolus Linnaeus, however recent studies show that the snowy owl is closely related to the horned owl genus, Bubo. It is the heaviest bird in North America, weighing from about 1.6 to 3 kg.ome other animals they depend on are voles and fishes. Snowy owls do not have many predators because of its large size, however they compete with animals such as golden eagles and peregrine falcons for prey. Also, they need to protect their nests from animals like the Arctic fox, dogs, and grey wolves.
