Red and white giant flying squirrel
The red and white giant flying squirrel ("Petaurista alborufus") is a species of rodent in the family Sciuridae. It is the largest species of giant squirrel and has blue eyes.
It is also known as the Chinese giant flying squirrel. At over a meter long including its tail, the red and white giant flying squirrel is the largest of its kind. Endemic to central and southern China and Taiwan, they inhabit dense hillside forests in mountainous terrain. They spend their days sleeping, emerging after sundown to forage in the trees. Their diet consists primarily of nuts and fruits, but also includes leafy vegetation as well as some insects and their larvae. Red and white giants move between trees by gliding, typically over distances of about 10–20 meters. This squirrel has a wide range and is relatively common, and the International Union for Conservation of Nature lists it as being of "least concern".
