The ears of snowshoe hares measure 62 to 70 mm from the notch to the tip. In regards to weight, snowshoe hares usually weigh between 1.43 and 1.55 kg, with males being slightly smaller than females.

One of the most significant physical adaptations of snowshoe hares is their large hind feet, which are designed to help them move efficiently in their environment. Measuring 117 to 147 mm in length, these large feet serve as a sort of natural snowshoe, helping the hare to move quickly and effortlessly through deep snow. The dense fur that covers their feet provides additional insulation and traction on slippery surfaces.

In summary, the physical characteristics of snowshoe hares, such as their fur, ears, size, hind feet, and tail, play a vital role in helping the animals to adapt and survive in their environment. These features, including their color-changing fur, large hind feet, and overall size and shape, make snowshoe hares an interesting and unique species within the animal kingdom.

Geographical Distribution

The snowshoe hare (Lepus americanus) is a highly adaptable species found primarily in North America, spanning from the northern regions of Canada and Alaska, down to parts of the United States such as the Rocky Mountains and Appalachian Mountains.

In Canada, these hares occupy vast territories, including the provinces of Yukon, Manitoba, Saskatchewan, Alberta, and British Columbia. They thrive in a variety of ecosystems, such as coniferous and boreal forests, which provide them ample shelter and sustenance. Notably, Newfoundland is also a habitat for the snowshoe hare, where it has been introduced successfully.

In the United States, their range spans from the western side of the country in states like Montana, Oregon, and California, to the eastern regions including New York, Virginia, Minnesota, and Michigan. In these areas, they reside predominantly in the mountainous regions, such as the aforementioned Rocky Mountains and Appalachian Mountains.

The snowshoe hare is well-adapted to its environments, as evidenced by its enlarged hind feet, which allow for efficient travel over snow-covered terrain. Its distribution throughout a multitude of ecosystems across North America speaks to its ability to effectively adapt to a wide range of habitats and climates.


Snowshoe hares primarily consume a variety of plants to fulfill their dietary needs. During the summer months, they prefer to eat herbaceous plants and the new growth of woody vegetation. This includes feasting on grasses, bark, and tender leaves from trees.

In the winter season, as the availability of plants changes, they shift their focus to consuming twigs, buds, and bark on shrubs and trees. Snowshoe hares are known to leave behind well-defined browse lines, also known as “hare lines,” due to their heavy browsing on available vegetation.

Just like snowshoe hares, rabbits also maintain a plant-based diet. If you’re uncertain about the dietary preferences of rabbits, you can learn more in the post Are Rabbits Omnivores? which discusses whether rabbits are omnivores or herbivores.

Reproduction and Survival

The reproduction process of snowshoe hares begins in the spring, typically during the months of March and April. Both males and females participate in mating multiple times with various partners throughout the year. Snowshoe hares can have two to three litters annually, with an average of five leverets per litter.

The gestation period for females is approximately 35 days. After giving birth, females are known to remate soon after, in order to produce more offspring during the breeding season. Leverets are born well-developed with fur and their eyes open, which is essential for their survival in the natural environment.

In terms of survival, snowshoe hares have developed several adaptations to increase their chances of living. One such adaptation is their large hind feet covered with thick fur, which allow them to move easily on snowy surfaces without sinking. Their unique feet also protect them from frigid winter temperatures, enabling them to thrive in North America’s colder regions.

Snowshoe hare populations typically experience cycles of eight to eleven years, with fluctuations in population density depending on varying factors within their environment. These cyclic changes are driven by alterations in their survival and reproduction rates, essentially affecting the overall population stability throughout boreal forests in North America.

Behavior and Adaptations

The Snowshoe Hare exhibits several interesting behaviors and adaptations that help it survive in the challenging environments that it inhabits. They are primarily nocturnal, being more active at night when it’s easier for them to remain secretive and shy (National Wildlife Federation). This nighttime activity allows them to forage for food, mostly plants, grasses, and new tree growth, while staying hidden from predators.

During the winter months, one of the most striking adaptations of the Snowshoe Hare is its ability to change its fur color to white, providing effective camouflage against the snow. In the summer, it has a brown coat that helps it blend in with the surrounding vegetation (Wikipedia). This color-changing ability allows them to remain concealed from predators throughout the changing seasons.

Moreover, Snowshoe Hares have a unique talent for freezing in place when they sense danger. This behavior, combined with their camouflage, makes them difficult for predators to spot (Are Rabbits Smart?). Additionally, their namesake “snowshoes” are another important adaptation. Snowshoe Hares have large, fur-covered feet that allow them to travel quickly and efficiently across the snow, escaping predators while minimizing the risk of sinking.

Notably, Snowshoe Hares are excellent swimmers, which can also help them escape danger by jumping into the water and swimming away from potential threats (Snowshoe Hare Facts). Furthermore, their ability to make various sounds like honking, growling, and clucking (What Sound Does a Bunny Make?) can also be used as forms of communication or as warning signals to other hares in the area.

In summary, the Snowshoe Hare exhibits numerous behaviors and adaptations throughout the year that enable its survival in diverse environments. Their nocturnal nature, exceptional camouflage, and specialized physical features all work together to allow them to evade predators and thrive in their natural habitats.

Predators and Preys

Snowshoe hares are an essential prey item for various predators in their ecosystem. A primary predator of the snowshoe hare is the Canada lynx. The rise and fall in the numbers of hares and lynxes have historically been observed to follow a cycle, making the snowshoe hare a well-known case study for understanding predator-prey relationships in biology.

Apart from the Canada lynx, other predators of snowshoe hares include bobcats, fishers, American martens, long-tailed weasels, minks, foxes, coyotes, domestic dogs, domestic cats, wolves, cougars, owls, hawks, golden eagles, and crows.

During the pursuit of prey, snowshoe hares use their agility and speed to their advantage. They tend to run in zig-zag patterns, which helps them evade and escape predators. Although high predation rates typically lead to 85 to 100% of the mortality in snowshoe hare populations, their rapid reproductive rates ensure a continuous supply of hares for their predators.

Regarding their diet, snowshoe hares are highly adaptable in feeding on various vegetation types. In the summer, they consume herbaceous plants and new growth from woody plants, while in winter, they feed on twigs, buds, and bark. This diverse diet helps ensure their nutritional needs are met throughout the year.

In summary, the snowshoe hare serves as an essential prey in its ecosystem, supporting a diverse group of predators. Its diet and evasive escape tactics contribute to its survival, highlighting the intricate balance between predator and prey relationships in nature.

Population Dynamics

Snowshoe hare populations are known for their cyclic dynamics, which consist of periodic increases and declines in their numbers. These cycles have been observed across the boreal forests of North America, with fluctuations in abundance happening every 10 years (Lepus americanus).

A primary factor contributing to these population cycles is the predator-prey relationship between snowshoe hares and Canadian lynx. Lynx populations follow the snowshoe hare population with a 1- to 2-year time lag. This means that when hare populations increase, lynx numbers also tend to rise within a couple of years. Additionally, the population cycles seem to radiate from central Canada, with the peak in central Canada occurring about 2 years before the peak in Yukon Territory and Alaska.

The unique landscape in which snowshoe hares reside also plays a role in shaping their population dynamics. Sink habitats, or open areas, prevent the buildup of high hare densities. As a result, the animals routinely move through complex fragmented landscapes in search of suitable habitats. This process of movement contributes to the cyclic nature of their populations, as well as their ability to interbreed and maintain genetic diversity.

Late-litter juveniles are another factor contributing to the population dynamics of snowshoe hares. Providing a continuous influx of new individuals into the population, they help to maintain the population size and structure.

In summary, the population dynamics of snowshoe hares are influenced by several factors, including predator-prey relationships, landscape structure, and late-litter juveniles. These factors combine to produce the characteristic cyclic fluctuations in hare populations, which are observed in the boreal forests of North America.

Habitat and Ecosystem

Snowshoe hares (Lepus americanus) inhabit a variety of ecosystems, primarily making their home in coniferous and boreal forests. These forests stretch across vast regions of North America, including the Rocky Mountains, the Appalachian Mountains, the Pacific Northwest, New England, Alaska, Minnesota, Michigan, and Montana. Due to their preference for cooler environments, the dense forests found on mountaintops like the Rockies and near the Canadian border are favored habitats for these adaptable animals.

Boreal forests, also known as northern forests, are dominated by evergreen coniferous trees such as pines, spruces, and firs. The climate in these regions is characterized by long, cold winters and short, cool summers. Snowshoe hares thrive in these conditions, owing to their unique adaptations for surviving in the snow and frigid temperatures.

In addition to boreal and coniferous forests, snowshoe hares can be found in open areas and at various elevations, depending on the geographical location. These habitats can include meadows, swamps, and other areas with dense shrubbery. In such environments, they rely on the thick underbrush and ground cover to provide protection from their numerous predators.

The presence of snowshoe hares is crucial for maintaining the balance in their ecosystems. As a primary prey species for a wide range of predators, such as lynx, coyotes, and raptors, their population size and reproductive success are essential to the health of the food web. In turn, these predators help regulate the snowshoe hare population, maintaining equilibrium within the habitat.

Key Features of the Snowshoe Hare’s Habitat:

  • Coniferous and boreal forests
  • Mountainous and near-Canadian border locations
  • Adaptable to varying elevations and some open areas
  • Dense underbrush and ground cover for protection
  • Important element in the food web

Conservation Status and Threats

The Snowshoe Hare (Lepus americanus) is currently listed as a species of Least Concern by the International Union for Conservation of Nature (IUCN). This designation indicates that the population of snowshoe hares is generally stable and not experiencing significant decline.

However, there are certain factors and threats that could impact the hare’s population in the future. One significant challenge is climate change. Rising temperatures, unpredictable precipitation patterns and reduced snow cover can influence the availability of food and habitat for the hare. As their habitat gets impacted, hares may face difficulties in finding suitable shelter and evade predators more efficiently.

In addition, forest loss and degradation can also pose a threat to the snowshoe hare. With the decrease in young forest stands, particularly lodgepole pine (Pinus contorta), the availability of optimal habitat for the hares gets reduced. Young lodgepole pine stands are critical for hare populations, especially in some western mountain regions.

Another concern is the predation risk associated with climate change. Snowshoe hares rely on seasonal coat color change as camouflage from predators, transitioning from brown in the summer to white in the winter to match the snow-covered environment. However, with shorter winters and decreased snow cover, the hares may be more vulnerable to predation, as their white coat would become more conspicuous against a less snowy background.

To address these potential threats, conservation efforts should focus on adaptive management strategies that preserve and improve snowshoe hare habitat quality. This could include promoting the growth of young forest stands and minimizing the negative impacts of human activities on the hare’s population and habitat.

In conclusion, while the snowshoe hare population is currently stable, continued monitoring and proactive conservation efforts are essential for ensuring the long-term survival of this key species.
