Owls do not hibernate, but some species do migrate in regular or random patterns
. Owls are well-adapted to survive the harsh winters, and they have thick feather coats that cover their bodies as well as their legs and feet.
They also have excellent eyesight and directional hearing that help them locate prey concealed by vegetation or snow. For the most part, because they have adapted to survive in colder weather, owls do not have a need to migrate either.
They also don’t have the innate instinct to migrate that several bird species have. However, some species of owls do engage in movement during the winter that is like migration. For example, the Short-eared Owl and the Northern Saw-whet Owl are two species of owls that migrate south for the winter. Snowy Owls breed in the Arctic then wander toward the south, staying wherever they can find food. Some Burrowing Owls spend their whole life in one place, but others migrate every spring and fall. In summary, while some species of owls do migrate, most owls do not migrate or hibernate.

What Are Some Owl Species That Migrate, And What Are Their Migration Patterns?
Some species of owls migrate, while others do not.
The timing of migration is more closely related to food availability than temperature.
Here are some owl species that migrate and their migration patterns:
- Short-eared Owl: This species flies south for the winter in North America but stays on the continent.
In other parts of the world, like Europe and Asia, they take transcontinental flights.
- Northern Saw-whet Owl: These owls were once thought to be non-migratory, but they actually travel at night, unseen.
They are southbound come fall.
- Snowy Owl: These owls breed in the Arctic and then wander toward the south, staying wherever they can find food.
Some North American Snowy Owls winter in southeastern Canada, the upper Great Lakes states, and New England.
It appears that Snowy Owls typically migrate during their first year of life.
- Burrowing Owl: Some burrowing owls spend their whole life in one place, but others migrate every spring and fall with the regularity of a bluebird.
- Northern Hawk Owl: This species is known to migrate, but their migration patterns are not well understood.
It is worth noting that some owls may engage in a behavior known as “partial migration,” where they move to different areas within their range in response to changes in food availability.
Additionally, some species of owls, such as the great horned owl and the barred owl, are non-migratory and remain in the same area year-round.
How Do Owls Prepare For Migration Or Hibernation, And What Physiological Changes Occur In Their Bodies During These Periods?
Owls have unique adaptations that allow them to survive in cold weather, so they do not hibernate like some other animals.
However, some species of owls do engage in movement during the winter that is similar to migration.
Here are some ways owls prepare for winter and the physiological changes that occur in their bodies:
- Thick Feather Coverings: Owls have thick feather coats that cover their bodies, legs, and feet, providing insulation and protection against the cold.
- Adapted Physiological Features: Owls have warm feathers, a blood flow system in their feet to prevent heat loss, and keen hearing that helps them locate prey even in snowy conditions.
- Reduced Activity: Some non-migratory owls may become less active during colder months and spend more time roosting.
This reduced activity helps conserve energy during periods of limited food availability.
- Partial Migration: While most owls do not migrate, some species may engage in a behavior known as “partial migration”.
This means that only certain individuals or populations of owls within a species migrate to different regions in the winter, while others remain in the same area year-round.
It’s important to note that not all owl species exhibit the same behaviors during winter.
Some owls may remain active and even breed during the colder months.
Overall, owls have evolved various strategies to survive and thrive in cold weather without the need for hibernation or extensive migration.
Are There Any Factors Or Environmental Cues That Influence Whether An Owl Species Migrates Or Hibernates?
Factors and environmental cues that influence whether an owl species migrates or hibernates include:
- Habitat Conditions: If an owl’s current habitat becomes inhospitable due to factors such as habitat loss, degradation, or extreme weather, some owl species may migrate to new areas.
- Weather: Changes in weather, particularly colder temperatures, can affect the behavior of owls.
Some non-migratory owls may become less active during colder months and spend more time roosting to conserve energy.
- Food Availability: The availability of prey can influence whether an owl species migrates or hibernates.
If there is a scarcity of food in their current habitat, some owl species may choose to migrate to areas with better food sources.
However, some owl species, such as snowy owls, may choose to visit new areas to find new food sources instead of hibernating.
- Breeding Season: For some owl species, winter is actually their breeding season.
They are adapted to live and hunt in harsh weather, and they remain active during the cold season.
It’s important to note that not all owl species migrate or hibernate.
Some owl species may remain in their habitats and endure the harsh conditions of winter.
Additionally, individual owl species may exhibit different behaviors, and there can be variations within species as well.
