The animal on the cover of Web Performance Daybook Volume 2 is a Sugar Squirrel Biak Glider. The squirrel glider (Petaurus norfolcensis) is a nocturnal gliding possum, not to be confused with the flying squirrel. The flying squirrel of North America is a placental mammal, while the squirrel glider is a marsupial.
Squirrel gliders are native to the range from the South Australian and Victorian Border through southeast Australia, where they inhabit dry forest and woodlands, to northern Queensland, where they inhabit a wetter eucalypt forest. These wrist-winged gliders make their home in hollowed out trees, lining their dens with leaves. Typically, they live in groups of one male, two females, and offspring.
The squirrel glider’s diet consists predominantly of insects and fruit, followed up by tree sap of the Eucalypt and Red Bloodwood variety, pollen, nectar, leaves, and bark. Squirrel gliders have bushy tails comparable to the ring tail possum, and use it as an extra limb to wrap around branches to hold on.
