1. What Exactly is a Flying Squirrel?
A flying squirrel isn’t a bird or a bat, but a unique type of squirrel known for its ability to glide through the air. Often called “gliding squirrels,” they belong to the tribe Pteromyini within the squirrel family (Sciuridae). These nocturnal creatures possess a specialized membrane, called a patagium, extending between their front and hind legs, enabling them to glide from tree to tree.
1.1 What is the Scientific Classification of Flying Squirrels?
Flying squirrels are classified within the tribe Pteromyini, which is part of the larger squirrel family, Sciuridae. Here’s a more detailed breakdown:
- Kingdom: Animalia (Animals)
- Phylum: Chordata (Animals with a spinal cord)
- Class: Mammalia (Mammals)
- Order: Rodentia (Rodents)
- Family: Sciuridae (Squirrels, chipmunks, marmots, etc.)
- Subfamily: Sciurinae
- Tribe: Pteromyini (Flying Squirrels)
Within the Pteromyini tribe, there are approximately 50 different species of flying squirrels, grouped into 15 genera. The two species native to North America are the Northern Flying Squirrel (Glaucomys sabrinus) and the Southern Flying Squirrel (Glaucomys volans).
1.2 What Are the Key Characteristics of Flying Squirrels?
Flying squirrels possess several distinctive characteristics that set them apart from other squirrels:
