Why is the Northern Flying Squirrel an Endangered Species?northern flying squirrel why uis it endangered species

The Northern flying squirrel has several unique characteristics that make it an endangered species. While clumsy on the ground, they can glide gracefully through trees. Its erratic body temperature, high temperature preference, and reproductive cycle help explain the squirrel’s declining numbers. But, why is it an endangered species? These are questions that we will explore in this article. Read on to learn more about this charismatic animal.


A recent draft of Pennsylvania’s wildlife action plan calls for efforts to protect the northern flying squirrel. These efforts should include establishing guidelines for forest protection within five miles of known populations of northern flying squirrels. The action plan also calls for monitoring nest box placement. In addition to monitoring nest box placement, monitoring the distribution of the flying squirrel’s distribution and the number of individuals is recommended. The draft report also recommends protecting the species’ habitat in Pennsylvania’s eastern forestlands.

The southern flying squirrel has a wider distribution than the northern flying squirrel, but its range is expanding north and the latter is contracting. Currently, the northern flying squirrel exists in three subspecies in eastern U.S. states, including Pennsylvania, and two subspecies are federally endangered. Two subspecies of the species are common in other areas of the country, including boreal forests. However, the northern flying squirrel is endangered because of the destruction it is undergoing from predators.


The decline in numbers of the northern flying squirrel may be due to the introduction of a parasite, Strongyloides robustus, which affects its diet and reproduction. While the disease does not cause symptoms in the northern flying squirrel, it has been found in southern flying squirrels. Another parasite may be the balsam woolly adelgid, an invasive species that attacks firs in Europe. Unfortunately, this species was accidentally introduced to North America in the early 1900s.

While the habitat of the northern flying squirrel is not directly harmful to humans, its numbers are reducing rapidly, especially as the number of logging and development increases. These squirrels are often found in buildings, where they may disturb residents, or disrupt wildlife traps. While there are no known harmful effects to human beings, their presence in houses could be a problem for trappers during the winter. In addition to being a nuisance in humans, the northern flying squirrel can also get into traps intended for martens and minks. However, the squirrel has no direct effects on human beings, other than disturbing their nests and seeds.

Body temperature

The northern flying squirrel has a body temperature range of 35°F to 50°F. This is the same range that humans experience in the winter, when they are forced out of tree cavities and into brooms. Brooms are abnormal branches caused by tree rust diseases. Northern flying squirrels tend to live in groups of two or more. They are an endangered species because they are becoming more difficult to find and are becoming an increasingly rare sight.

This cold-weather tolerant species has a limited diet. It can become heterothermic in turbulent weather, cold conditions, and short periods without food. It uses its body’s energy reserves to survive through winter and short periods of food scarcity. While it is primarily a grazer, it sometimes uses its mast to create food or forage. It also eats fungi, lichens, and staminate cones.

Reproductive cycle

The reproductive cycle of northern flying squirrel is similar to that of other types of flying squirrels, but there are some key differences. Female northern flying squirrels mate in late winter, and then lay eggs for a period of about 40 days. The young of this species weigh between five and six grams (0.20 and 0.25 oz), and develop rapidly. They can begin foraging for food by about six weeks of age. Northern flying squirrels also live in groups of eight or more.

In cold environments, tree cavities are not a hindrance. This species seems to be opportunistic and generalist, using several types of nesting sites. In fact, practices that ensure the persistence of large live cavity trees increase the relative use of tree cavities by this species. In addition, northern flying squirrels have been linked to an increase in the prevalence of ectomycorrhizal fungi, which enhance plant health. They also serve as prey for owls, hawks, and martens.

Nesting season

The Northern Flying Squirrel has a limited breeding season. These squirrels can breed anytime from March to late June, and are capable of giving birth to a single litter. These animals can be found in coniferous forests and deciduous forests, and are attracted to mature trees with a large number of dead snags. They feed on a variety of foods, including nuts, acorns, fungi, lichens, and fruits. They produce between one and six young per litter.

The range of the northern flying squirrel is vast, but it is often found in small, disjunct populations. Because of the population decline, the species is threatened with extinction. Despite its large range, researchers have been able to document the genetics of individual populations and determine whether or not they’re declining. This means that the northern flying squirrel may be on the brink of extinction. In some cases, the species is already extinct, but despite this, conservation efforts are making great strides.


Diet of northern flying squirrels is an important part of the biology of these birds. Their range is narrow, but it’s not completely unknown. The species is threatened by development, overhunting, logging, and hunting. In Pennsylvania, the species is in danger of extinction due to habitat loss caused by urbanization. Another threat to the species is the hemlock wooly adelgid infestation, which destroys fungi that the birds need to grow.

The diet of northern flying squirrels is quite diverse. It includes tree sap, fungi, fruits, and insects. It also eats bird eggs and carrion. In fact, the species is the only flying squirrel in North America, and their population is rapidly declining. To protect their population, the federal government has implemented various conservation measures to protect it. Listed below are some important facts about the diet of northern flying squirrels.
