Snowy Owl Life History

The Snowy Owl (Bubo scandiacus) is a charismatic and iconic bird of prey inhabiting the vast Arctic tundra and occasionally venturing into more temperate regions during winter migrations. 

Renowned for its striking appearance, the life history of the Snowy Owl encompasses various aspects, from its dietary habits and preferred habitats to its breeding behavior, potential health threats, and ongoing conservation efforts.



Snowy Owls are opportunistic hunters with a diverse diet. Their primary prey includes lemmings, voles, and other small mammals, which form the bulk of their diet, especially during the breeding season. 

These skilled predators are also known to capture birds, ranging from ptarmigans to waterfowl, and occasionally fish. 

Their powerful talons and sharp beaks make them effective hunters, ensuring a varied and adaptable diet to sustain their energy needs.


The Snowy Owl is adapted to the extreme conditions of the Arctic tundra, where it nests and raises its young. 

Their habitat preference includes expansive, open areas where they can utilize their keen eyesight to spot potential prey. 

During winter migrations, they may be found in a broader range of habitats, such as coastal regions, grasslands, and even urban areas, displaying their adaptability to diverse environments.

Range Map

The Snowy Owl’s range is circumpolar, encircling the Arctic regions of North America, Europe, and Asia. 

The breeding range is primarily in the Arctic tundra, with some populations migrating southward during the winter months. 

Detailed range maps help researchers and conservationists understand their movements, crucial for effective conservation strategies and monitoring population trends.



Snowy Owls exhibit a unique breeding behavior, with pairs forming in the Arctic during the summer months. 

Females construct nests on the ground, typically on elevated sites like rocks or mounds, using a combination of moss, lichens, and feathers. 

After a relatively short incubation period, chicks hatch, and both parents actively participate in caring for the offspring. 

The Arctic summer’s continuous daylight allows for extended hunting hours to meet the demands of feeding the growing chicks.


While Snowy Owls are relatively hardy, they can be susceptible to certain diseases and environmental stressors. Avian diseases, such as aspergillosis and avian pox, can affect individuals. 

Climate change and habitat degradation also pose indirect threats by altering the availability of prey species. Monitoring health and addressing emerging diseases are crucial components of conservation efforts.


In cases where Snowy Owls are affected by diseases or injuries, rehabilitation efforts may be undertaken by wildlife professionals. 

Treatment involves a combination of veterinary care, nutritional support, and rehabilitation to ensure the birds can be released back into their natural habitat.

 Timely intervention and proper care contribute significantly to their chances of survival.



Conservation initiatives for Snowy Owls focus on preserving their Arctic breeding grounds, managing human-wildlife conflicts, and monitoring their populations during winter migrations. 

Habitat protection, research on climate change impacts, and community engagement are integral to safeguarding these magnificent birds. 

Conservation efforts also involve education to raise awareness about the importance of maintaining the delicate balance of Arctic ecosystems.

The Snowy Owl’s life history is a testament to its adaptability and resilience in the harsh Arctic environment. 

Understanding their dietary needs, preferred habitats, breeding behaviors, potential health threats, and conservation requirements is crucial for ensuring the continued survival of this awe-inspiring species in the wild.
