Is a rodent mammal, measuring between 35 and 45 cm in length, of which almost half belong to the tail. On the front limbs, the thumb is reduced, but the other 4 fingers are well developed and endowed with long, curved and sharp nails. Squirrels are sometimes considered pests due to their propensity to chew various edible and inedible objects, and their stubborn persistence in trying to get what they want. Their characteristic feature of gnawing also helps them keep their teeth sharp, and because their teeth grow continuously, this prevents their overgrowth. Sometimes, squirrels chew even through plastic and metal, to get to the food.
Types of common squirrels in new jersey
Yes, I realize that it’s a bit strange that some Eastern Gray Squirrels have black fur, but it’s true! These black squirrels appear as a morph, and genetically speaking, it’s believed to result from a faulty pigment gene. No one is really sure why the black morph evolved, but several theories have been offered. Some scientists think it may be a selective advantage for squirrels that inhabit the northern ranges to help them absorb heat since the color of black conducts heat best.
Scientific Name: Tamiasciurus hudsonicus
Average Length (Including tail): 11- 14 inches / 28 – 35.5 cm
Weight: 7.1–8.8 oz / 200–250 g
Lifespan: They experience severe mortality during their first year, as only about 20% of babies survive. For individuals that survive the first year, the average lifespan is still only 2.3 years, with a maximum lifespan of 8 years. Predators include bobcats, coyotes, hawks, owls, foxes, American Martens, and Canadian Lynxes.
The American Red Squirrel is widespread across New Jersey and easy to identify when compared to other squirrel species. As the name suggests, they have a reddish color and white belly that makes them easy to distinguish. Size-wise, they are both MUCH smaller than both gray and fox squirrels but larger than chipmunks.
The southern flying squirrel or the assapan (Glaucomys volans) is one of three species of the genus Glaucomys and one of three flying squirrel species found in North America. It is found in deciduous and mixed woods in the eastern half of North America, from southeastern Canada to Florida. Disjunct populations of this species have been recorded in the highlands of Mexico, Guatemala, and Honduras.
The northern flying squirrel (Glaucomys sabrinus) is one of three species of the genus Glaucomys, the only flying squirrels found in North America. They are found in coniferous and mixed coniferous forests across much of Canada, from Alaska to Nova Scotia, and south to the mountains of North Carolina and west to Utah in the United States. They are light brown with pale underparts and grow to a length of 25 to 37 cm (10 to 15 in). They are proficient gliders but uncoordinated walkers on the ground. They feed on a variety of plant material as well as tree sap, fungi, insects, carrion, bird eggs and nestlings. They mostly breed once a year in a cavity lined with lichen or other soft material. Except when they have young, they change nests frequently, and in winter a number of individuals may huddle together in a shared nest. Unlike most members of their family, flying squirrels are strictly nocturnal.
