They are one of the smallest owls in North America and threatened by habitat destruction and land use change. Snowy owls are mostly white with narrow, sparse brown bars and spots. They are among the largest North American owl species and threatened by climate change impacts to habitat and prey.
Why are snowy owls a keystone species?
Owls, and other birds of prey, are often Keystone Species The impacts of keystone species are usually greater than their numbers. For example, one owl can eat a large number of rodents and small mammals, with few animals preying on the owl in return.
How do snowy owls help the environment?
Snowy owls play an essential role in controlling the numbers of rodents in the Arctic tundra environment. One snowy owl can eat up to 1600 rodents in a year.
Are snowy owls friendly?
Snowy owls are typically solitary and aren't known to be affectionate toward each other or humans. Since they're most active at night and rely on sizable live prey as their main diet, they don't make a good pet.
Which owl is the rarest?
The Blakinston's fish owl – Arguably the rarest owl in the world. The Blakinston's Fish owl, also the largest owl species is arguably the rarest owl in the world due to their widespread loss.
How rare is a snow owl?
With only an estimated 30,000 snowy owls left in the world, it's extremely rare to see the vulnerable species out in the wild. Seeing one in an urban setting is especially extraordinary considering they spend most of their lives in the remote Arctic.
What do owls do for the ecosystem?
As predators, owls play an important role in the environment by controlling small animal populations. Because mammals are a primary prey item, this can be especially beneficial to humans, reducing the amount of food lost each year to rodents. Barn owls are also a food source for other animals.
How does the snowy owl affect humans?
Snowy Owls have been known to attack humans while on nesting grounds. Males are generally the aggressors and protectors of the nest and territory. However, there have been cases recorded of female Snowy Owls attacking humans when their young are near (Parmelee, 1992).
Why are owls important in the food chain?
All owls are predators; they depend on other animals for food. However, very few predators feed on owls (except sometimes other owls). In fact, owls often eat other predators, such as weasels, bats, shrews and insect-eating birds. Therefore, owls hold a position at the top of the food chain.
What will happen if the number of owl goes down?
In an ecosystem if one thing goes wrong then all organisms will fall apart , so if the whole race of owls were to die then the food chain and life cycle wouldn't be able to work properly.

Adult snowy owls can reach speeds up to 46 miles per hour. What is the wingspan of a snowy owl? A snowy owl's wingspan averages about 5 feet in length.
How smart are snowy owls?
Owls are generally not “smart,” at least when being compared to the most intelligent members of the avian world - the corvids and parrots. Despite their large heads, an owl's skull is small compared to their bodies, and their cognitive abilities aren't impressive based on a handful of studies.
How far can snowy owls see?
Experiments indicate that snowy owls can detect prey from as far as 1.6 km (0.99 mi) away. Snowy owls generally use a rise or, occasionally, a perch while hunting.

How big are snowy owls?
Size: Body: 20 to 28 inches; wingspan: 4.2 to 4.8 feet. Weight: 3.5 to 6.5 pounds. These large owls mainly live in the Arctic in open, treeless areas called tundra. Snowy owls perch on the ground or on short posts. From there they patiently watch for prey.
How long does it take for snowy owls to lay eggs?
Sometimes, if there is not enough prey around to feed baby owls, the adult pair won't lay any eggs at all until the supply of food improves. The female snowy owl sits on her eggs until they hatch. The male feeds her while she keeps their eggs warm and safe. After about one month, the eggs hatch.
Why are snowy owls so far south?
Since the numbers involved in this season's flight are so large, several have gone farther south and have been detected. The great majority of the owls seen at southern latitudes this season have looked like young birds, heavily marked with black. And yes, snowy owls are known to be susceptible to aspergillosis. The spores that cause the infection are found worldwide, but the owls' immune systems apparently protect them from infection until they become highly stressed—and that may be more likely to happen with hungry young birds in unfamiliar surroundings.
How many eggs do snowy owls lay?
But that's one of the most fascinating things about Snowy Owls: the number of eggs that the females lay will change from year to year, depending on how much food is available. When food is scarce, they may lay only three to five eggs (or sometimes none at all). When food is abundant, as in a year when lemmings are in peak numbers, they may lay seven to eleven eggs, or even more. This is part of the reason why their numbers can increase so rapidly in a good season.
Where do owls nest?
S nowy owls nest all across the Arctic tundra of Alaska, Canada, Greenland, Scandinavia, and Russia. One careful estimate put their total world population at about 300,000. However, their numbers undoubtedly vary from year to year, rising and falling with changes in food supply and other factors, and they probably have declined overall in the last century.
Where are owls found in the summer?
But we do know that lemmings (the owls' favorite prey in summer) were abundant in northern Quebec last summer, and the owls apparently had very good breeding success there. Elsewhere in the Arctic, including farther west, it wasn't such a productive season.
Can snowy owls get aspergillosis?
And yes, snowy owls are known to be susceptible to aspergillosis. The spores that cause the infection are found worldwide, but the owls' immune systems apparently protect them from infection until they become highly stressed—and that may be more likely to happen with hungry young birds in unfamiliar surroundings.
Do snowy owls make hoarse hooting sounds?
Most owls live in forest and are active at night, so communicating by voice is a very important part of their behavior. Since snowy owls live in open country, and they're active in daylight during the breeding season, they have less need for far-carrying sounds. Still, they do make hoarse hooting sounds as part of their territorial defense. They also make a variety of other sounds during interactions with their own kind, including shrieks, cackling barks, mewing cries, and snapping their bills shut loudly. Lone snowy owls on the wintering grounds are often silent.

Why do snowy owls need a pound of prey?
That myth comes from a 1958 Disney documentary, White Wilderness, in which filmmakers herded a group of lemmings off a cliff to create a dramatic scene.) Snowy owls need as much as a pound of prey every day to survive the harsh arctic conditions , and catching lemmings is more efficient than hunting seabirds.
What do snowy owls eat?
Though snowy owls will eat voles, arctic hares and smaller birds, a study by the Owl Research Institute showed that out of 43,000 prey animals collected at snowy owl breeding sites, 90 percent were lemmings. These small, mouselike rodents stay active all winter long, eating moss when there are no green leaves available. Everything has to be just right for them to flourish. Too much snowmelt too early in the season and the lemmings are forced to spend more time aboveground, making them susceptible to every predator in the area. Too little snowmelt and there isn’t enough vegetation for the lemmings to eat. (One risk lemmings don’t face is suicidally following each other off cliffs. That myth comes from a 1958 Disney documentary, White Wilderness, in which filmmakers herded a group of lemmings off a cliff to create a dramatic scene.) Snowy owls need as much as a pound of prey every day to survive the harsh arctic conditions, and catching lemmings is more efficient than hunting seabirds.
