There are 44 species of the squirrels exist in this world. Flying squirrel are one of the astounding types of squirrels, also recognized as Petauristini or Pteromyini. These squirrels are capable of flying. However, they do not fly like other birds or as bats do. Nevertheless, they have an ability of gliding on trees.
They glide with the assistance of furry, comprises of a parachute-like membrane, which is known as patagium. It helps in stretching these squirrels from wrist to the ankle.

They have longer limbs than other birds, but remaining bones are shorter including hand and foot. They can control their glide path using the limbs as well as the tail while flying.
According to the studies, the flying squirrels were discovered more than 17 million years from now, and they are monophyletic. Most of them are omnivorous and nocturnal which means they eat fruits, flowers, seeds, insects, spiders, and bugs, etc.
The moment young squirrels born, at first, they are helpless and unable to take care of themselves. The mother squirrels look after them and feed them for about 6-8 weeks as well as teach the gliding skills. After two months they can fly their first flight.

Types of flying squirrels
There are more than 40 species of the flying squirrels found all around the world. From these species, there are two special types, North American and South American flying squirrel. They are found in the forests of north and southern part of Canada as well as in America.
The southern flying squirrel is 9-10 inches long and often weighed 2-2.5 ounces. Mostly, they breed in spring and deliver their babies in May or June. They reside throughout the North America, comprising the area of southern Canada as well as southern parts of Florida. Furthermore, they exist in areas around Minnesota and eastern Texas.
The northern flying squirrel is slightly long in size from 10-11 inches weighing 3-4 ounces. They mostly breed in late winters delivering their babies in April or May. These squirrels are the inhabitant of warmer places, so they are found in the northern Canada, Tennessee as well as southern parts of Alaska. They also live along the Pacific Cost.
Furthermore, both of these have dense and soft furry skin which embraces double shade. It looks grayish brown from outwards and creamy white from inside. Both of these typically give birth to 2-7 babies. Their eyes are larger than their body size.

Since they don’t travel on the ground, therefore, there are very few chances for a predator to prey these creatures.
Their size is one of the main features that distinguishes between these two flying squirrels. The southern flying squirrels are usually 9-10 inches long, whereas, the northern squirrels are 10-11 inches in length.
2. Diet and eating habit
Flying squirrels are the omnivores that mean they comprise characteristics of both herbivores and carnivores. Their food includes seeds, flowers, fruits, nuts as well as tree saps. The flying squirrels from the south are mostly carnivores, and they eat mostly eggs, insects, birds, and carrion.

Different types of flying squirrel are distributed in different regions depending upon their habitat. The northern flying squirrels have much scarcer distribution but are mostly live in the northeast, along with the west coast and Pacific as well as Montana. Whereas, the southern flying squirrel are found in almost every eastern region of US from Maine south to Florida and west from Minnesota south to Texas.
5. Lifespan and reproduction
Flying squirrels have an average lifespan of more than ten years when they are kept captive. However, their lives are reduced to half if they live in forests. They tend to give birth to new species once a year during the early spring and late winters.
The southern flying squirrels give birth twice a year. They can produce 2-7 babies at a time. When the baby squirrels are born, they are totally dependent on their mothers to be taken care.
