How Long Does A Grey Squirrel Live?
You’ve probably heard about the polygamous life of the gray squirrel, but are you wondering how long they actually live. Unlike many other small mammals, gray squirrels are polygamous. This article will discuss their diet, their life span, and how they can be vulnerable to predators such as red squirrels and raccoons. It will also provide some interesting facts about these nocturnal mammals.
Gray squirrels are polygamous
The question of whether gray squirrels are polygamous has long been debated. In 2001, an article in the Journal of Mammalogy explored interspecific competition among tree squirrels. The authors found that the grey and red squirrels are highly competitive for the same seeds. Therefore, it seems that the gray squirrels are not monogamous, but rather polygamous. But, is this polygamous behavior normal?
Female squirrels select their partners according to their close genetic relation. If they have a small litter, the female might adopt an orphaned grandchild. However, if their litters are large, the female may adopt an orphaned relative. Because resources are limited, females prioritize the females who are genetically close to them. This is called polygamous mating. In contrast, the males may adopt a grandchild to avoid competition.
They live up to 6 years in the wild
The life span of a gray squirrel is comparable to that of a red. Both sexes have a similar courtship ritual and one to ten males compete for the female’s attention. Mating usually occurs between one and two years of age. Breeding occurs in the spring, with litters born in early March and again in late July or early August. Adult females can bear one or two litters a year, while yearling females can only have one litter per year.
Though gray squirrels are hardy mammals, the harsh winter months can make their survival difficult. They are capable of surviving a winter with just a few food items. Moreover, the species may be susceptible to predators and even to parasitic infections. Their long life span and increased weight can lead to significant loss of fur. The lifespan of a grey squirrel in the wild is six to seven years, but this doesn’t mean that it’s immune from diseases.
They eat insects, caterpillars, and young birds
Eastern grey squirrels are opportunistic feeders, living in a variety of habitats. Their diet varies from season to season, but is generally comprised of acorns, seeds, nuts, berries, and young birds. In the summer, eastern grey squirrels eat acorns, acorn-like seeds, acorns, beechnuts, and pine seeds.
Eastern gray squirrels and foxes are herbivorous and primarily feed on acorns and nuts, although they occasionally prey on small rodents and birds. Eastern gray squirrels are also prey for bobcats, red foxes, minks, and raptors. Despite their varied diet, these animals are omnivorous and emit warning calls to warn other squirrels of their presence.
They are vulnerable to raccoons, snakes, and red squirrels
Grey squirrels are not the only victims of these predators, including foxes, raccoons, and red foxes. The Red Squirrel has become extinct in many parts of North America due to raccoons, which are not native to Great Britain. These animals have been known to carry nasty diseases, including the leptospirosis virus.
Some species of squirrels are vulnerable to aerial predators like raccoons and crows. Although the smaller birds don’t attack the squirrels, they will only eat the babies or the wounded ones. Snakes can climb trees and infiltrate the nests of red and grey squirrels. Since they build several nests in the same area, these predators are a threat to the squirrel population.
They can make hundreds of caches
Scientists have discovered that gray squirrels can make hundreds of caches per year. The vast number of locations around which they can store food is a testament to the creativity and resourcefulness of these animals. They use their memory and keen sense of smell to find hidden caches. These animals eat a lot during the winter, storing up fat reserves and sharing leaf-filled dens. Unlike humans, however, gray squirrels do not follow this rule and often leave multiple caches a day.
The exact process of finding a cache varies depending on the landscape, type of food, and other squirrels nearby. This process is so complex that researchers can’t study the exact science of squirrel behaviour without experimenting with real animals. The biologists have established that squirrels can remember where they hid a cache, and the retrieval rate is dependent on whether the mast crop is full or low. They also have an incredibly good spatial memory.
How long does a typical grey squirrel live?
