Glis glis is a large dormouse species known for its hibernation habits, sleeping for approximately 6-9 months during winter. For the remainder of the year, they average about 16 hours of sleep each day.
The Glis glis primarily inhabits mountainous areas in Northern Xinjiang, including locations such as Atele, Huocheng, Manas, and others. With a body length ranging from 85-120 mm and a maximum weight of about 100 grams, they resemble other rodent species, particularly squirrels. The Glis glis has a thick, soft fur coat and a long tail that aids in balance while moving through trees.

One of the most notable characteristics of the Glis glis is its nocturnal activity. During the day, they often shelter in tree hollows or abandoned bird nests to evade predators and rest. At night, they venture out to forage and interact with their surroundings.
The Glis glis has a hibernation pattern lasting 6-9 months throughout the winter. Even in summer, aside from nighttime foraging, they also sleep throughout the day. Why do they sleep so much? The main reason is to adapt to their environment and ensure safety from potential threats posed by predators.

The diet of Glis glis is quite diverse. They consume nuts, seeds, fruits, small insects, and bird eggs. Additionally, they are known to eat tree bark and leaves, which helps maintain their health and provides essential energy for daily activities.
In The Art of War by Sun Tzu, it is stated: “Victory cannot be achieved through oneself, but can be achieved through the enemy.” This implies that when facing a strong opponent, one should wait rather than attack. For Glis glis, prolonged sleep helps them avoid predators during their most active periods. Furthermore, this sleeping pattern allows them to conserve energy, especially in environmental conditions where food is scarce. During hibernation, they can lose nearly half their body weight, transitioning from fat to thin, and their body temperature and breathing rate decrease significantly.
The Glis glis is primarily active at night.
The breeding season for Glis glis occurs in the summer, typically from June to August. Each litter can consist of 2 to 8 young after a gestation period of about 25 to 28 days. The young are nursed by their mother for approximately 4 weeks before they begin foraging independently. This period is crucial for the young to learn how to find food and avoid environmental threats.
The fur of Glis glis is thick and soft, varying in color from light gray to brown-gray, while the belly is usually white or light gray. Their bushy tail not only serves as a distinguishing feature but also helps keep them warm during winter.
Like many other rodent species, Glis glis stores food in the fall for winter use. However, when food is insufficient, they rely on burning body fat to survive. This can sometimes lead to unfortunate individuals starving during hibernation.

Glis glis plays an essential role in forest ecosystems. They help disperse seeds of various tree species, contributing to the biodiversity of the forest. This seed dispersal not only aids in tree growth but also creates a rich and diverse habitat for many other animal species. Nevertheless, the population of Glis glis may decline due to habitat loss and excessive logging.
Despite hibernating, Glis glis are not completely inactive. They enter a special sleep state called “torpid wakefulness,” during which their brain remains somewhat active, and their muscles may still tense. When sensing danger, Glis glis can quickly awaken and flee to protect themselves.
Glis glis is a unique rodent species with many interesting biological and behavioral characteristics. They not only play a vital role in forest ecosystems but also serve as an intriguing subject for research in ecology and zoology. Conserving and protecting the habitat of Glis glis is a crucial task to ensure biodiversity and ecological balance in forested areas.

The Glis glis is a testament to the remarkable adaptability and survival skills of wildlife in nature. With its prolonged hibernation habits and unique survival strategies, it not only avoids threats from predators but also conserves energy in harsh conditions. The existence of this species is a fascinating example of the richness and diversity of animal life on Earth.
Beyond Xinjiang, China, Glis glis is also found across Europe, from France, Germany, Italy to the Balkans and Turkey. They prefer living in broadleaf forests, especially in areas with oak, chestnut, and maple trees. These forests provide abundant food sources and safe shelter for them.
In their natural habitats, Glis glis typically seek out tree hollows, abandoned bird nests, or caves for shelter. Their excellent climbing ability allows them to easily navigate among high branches and forage for food.
