Summer Diet
In summer, Arctic hares have more food choices.
They munch on fresh grasses, sedges, and flowering plants.
These plants are full of nutrients and easy to find.
The hares also enjoy eating leaves from small shrubs.
They use their sharp front teeth to clip off tasty bits of vegetation.
Sometimes, they’ll even stand on their hind legs to reach higher leaves.
Arctic hares don’t just eat the green parts of plants.
They also dig for roots, which are packed with energy.
This helps them build up fat reserves for the tough winter ahead.
Winter Diet
When snow covers the ground, Arctic hares face a big challenge.
Many plants they like are hidden or dead.
But these clever animals have tricks to survive.
They use their strong claws to dig through snow and find food.
Moss and lichen become important parts of their winter menu.
These plants might not look tasty to us, but they’re lifesavers for Arctic hares.
In really tough times, Arctic hares might nibble on woody plants or bark.
It’s not their favorite, but it keeps them going.
They can also eat snow to get water, which is super handy in the frozen north.
Behavior
Arctic hares have some interesting habits.
They change their actions to stay safe and find food in the harsh Arctic.
Social Structure
Arctic hares can be both solitary and social.
They often live alone, but sometimes form groups.
These groups can have up to 200 hares!
In winter, Arctic hares gather in large numbers.
This helps them stay warm and safe from predators.
They huddle close together when resting.
During mating season, males fight for females.
The winners get to mate.
Females raise their young alone after giving birth.
Survival Techniques
Arctic hares are experts at staying alive in the cold.
They have thick fur that changes color with the seasons.
In winter, they’re white to blend in with snow.
In summer, they turn brown-gray.
These hares are fast runners.
They can zoom along at 40 mph! This speed helps them escape from hungry predators like wolves and foxes.
To stay warm, Arctic hares dig small holes in the snow.
These cozy spots protect them from icy winds.
They also help hide the hares from danger.
Arctic hares are good at finding food, even when it’s scarce.
They use their strong sense of smell to find plants under the snow.
Then they dig to reach their meal.
Reproduction and Lifecycle
Arctic hares have a unique breeding cycle adapted to their harsh environment.
They time their reproduction to make the most of the short Arctic summer.
Let’s look at how these furry creatures start and raise their families.
Breeding Season
Arctic hares breed during spring.
This happens when their white winter coat changes to a grayish-brown color.
The new color helps them blend in with the tundra plants that start to grow.
Female hares, called does, can have up to three litters each year.
But they usually only have one or two.
The gestation period is about 50 days.
Males, known as bucks, compete for the chance to mate.
They show off their strength by standing on their hind legs and boxing with their front paws.
Raising the Young
Baby arctic hares are called leverets.
They’re born with a full coat of fur and open eyes.
This helps them survive in the cold Arctic.
A mother hare can have 2 to 8 leverets in a litter.
The babies are able to hop around just a few minutes after they’re born!
Leverets grow quickly.
Their mom feeds them rich milk for about 2 months.
After that, they start eating plants like the adults do.
Young hares stay with their mom for a short time.
They learn important skills like finding food and avoiding predators.
By the end of summer, they’re ready to face the Arctic winter on their own.
Predators and Threats
Arctic hares face many dangers in their icy home.
Animals hunt them for food, while humans impact their habitat and numbers.
Common Predators
Arctic hares have to watch out for several hungry hunters. Arctic wolves, arctic foxes, and red foxes are always on the lookout for a tasty hare meal.
These swift predators chase the hares across the tundra.
In the sky, snowy owls and gyrfalcons pose a threat.
These birds swoop down silently to catch hares off guard.
On the ground, lynx use their keen senses to stalk arctic hares.
Their soft paws help them sneak up quietly.
Ermines, though small, are fierce hunters too.
They can follow hares into their burrows.
Human Impact
People affect arctic hares in different ways. Some hunt them for their warm fur and meat.
This can lower hare numbers if not done carefully.
Human activities change the tundra where hares live.
As people build and use more land, hares lose places to hide and find food.
Climate change is a big worry.
It’s making the Arctic warmer, which changes where plants grow.
This affects what hares can eat and where they can live safely.
Conservation efforts try to help.
By protecting land and limiting hunting, people hope to keep arctic hares around for a long time.
Adaptations
Arctic hares have evolved special features to thrive in their icy home.
These adaptations help them stay warm, safe, and well-fed in harsh conditions.
Physical Adaptations
Arctic hares have thick white fur that keeps them warm and hidden in the snow.
This coat changes color with the seasons.
In summer, it turns brown or gray to blend in with rocks and plants.
These hares have short ears and small noses.
This helps them lose less heat.
Their bodies are stocky with short limbs.
This shape keeps them warmer by reducing surface area.
Arctic hares have big, furry feet.
These act like snowshoes, helping them move easily on snow.

Ecological Role
Arctic hares play a key part in tundra ecosystems.
They affect plant growth and provide food for predators.
Their actions shape the Arctic landscape in small but important ways.
Impact on Ecosystem
Arctic hares are important herbivores in the tundra.
They eat plants like willows and grasses, helping to control plant growth.
This grazing can change how plants spread across the land.
These hares are also prey for many animals. Arctic foxes and snowy owls often hunt them for food.
When hare numbers go up or down, it affects how many predators can survive.
Arctic hares help spread plant seeds too.
As they eat and move around, seeds stick to their fur or pass through their digestive system.
This helps plants grow in new areas.
The hares’ digging can change the ground.
They make small holes for shelter, which can affect soil and plant life.
These actions, though small, add up to shape the Arctic ecosystem.
Conservation Status
Arctic hares face some challenges but are not currently at high risk.
Their population seems stable in most areas.
Some efforts are underway to protect them and their habitats.
Protection Efforts
Arctic hares are listed as a “least concern” species by the International Union for Conservation of Nature.
This means their numbers are healthy overall.
In Canada, arctic hares have no official conservation status.
This is because there isn’t enough data about their population.
Some groups are working to learn more about arctic hares.
They want to make sure these animals stay safe as the climate changes.
The arctic tundra where these hares live is changing fast.
Rising temperatures could affect their food and homes.
