It is also called the polar owl or the white owl. These birds live on the tundra in North America and the Palearctic.

They are very good at living in cold places. They are one of the largest types of owls in the world.

Most owls sleep during the day and hunt at night. However, snowy owls are often active during the day in the summer. This helps them make the most of the short Arctic summer.

These owls have special ways to find food.

Their lives are closely tied to lemmings that live on the tundra. When lemmings are not around, the owls can adapt to other prey. They often eat small mammals or northern water birds.

They will even eat carrion, which is dead animals. They usually build their nests on small rises on the ground.

A female lays a large clutch of eggs. A clutch is a group of eggs laid at one time. They often lay between 5 and 11 eggs. The eggs hatch at different times, so they are staggered.

Scientists have studied these birds for a long time.

Carl Linnaeus first described the species in 1758. He used the name Strix scandiaca in his book. Later, scientists used the name Nyctea. Now, many experts say they belong in the genus Bubo. This name means "horned owl" in Latin.

Genetic testing shows they are very close to the great horned owl. They may have split from other owls about 4 million years ago. This helps us understand how they changed over time.

There are many interesting facts about how they look.

Some snowy owls might even look like a lump of snow on the ground. This helps them hide in their white habitat.

Snowy owls are also very good travelers. They are nomadic, which means they move from place to place.

They rarely breed in the same spot every year. Sometimes they move far south in large numbers.

This movement is called an irruption. Sadly, the number of snowy owls is going down. Experts once thought there were over 200,000 birds. Now, there are probably fewer than 100,000 left in the world.
