Quick Answer
ARCTIC HARES ARE ATTRACTED BY FOOD SOURCES DURING THE WINTER, SPECIFICALLY LICHENS, MOSS, AND BARK, AS WELL AS THE SHORT PERIODS OF CLEAR SKY AND SUNLIGHT THAT ALLOW THEM TO SEE AND MOVE AROUND. THIS IS CRUCIAL FOR THEIR SURVIVAL IN THE EXTREME ARCTIC ENVIRONMENT. THEY ALSO FAVOR AREAS WITH LESS DEEP SNOW.
Habitat Preferences
Arctic hares thrive in areas with dense vegetation, such as lichens, moss, and low-growing shrubs. These food sources provide the necessary nutrients for their survival during the harsh winter months. When foraging, they use their keen sense of smell and hearing to locate these sources. In ideal conditions, they can eat up to 1.5 pounds (0.7 kg) of lichens and other vegetation per day.
Adaptations for Winter Survival
Arctic hares have several adaptations that enable them to survive the extreme winter conditions. Their thick coats of fur, which can be up to 6 inches (15 cm) long, provide excellent insulation against the cold. They also have large paws that act as snowshoes, allowing them to move easily through deep snow. When running, they can reach speeds of up to 30 miles per hour (48 km/h). This combination of adaptations and their ability to adapt their behavior to the changing environment makes them one of the most successful Arctic species.
Impact of Clear Skies on Behavior
The short periods of clear skies during the winter have a significant impact on the behavior of arctic hares. With the sun shining, they can see and move around more easily, allowing them to forage for food and escape predators. This is crucial for their survival, as they rely on these periods of clear skies to recharge and refuel. In areas with prolonged periods of cloud cover, the hares’ activity levels decrease significantly, making them more vulnerable to predators.
