The Feathertail Glider is a tiny gliding possum. She is characterised by her tail, which is as long as her head and body combined, and serrated along the edge, like a feather. It is prehensile, used to grip the branches, to balance herself as she leaps from tree to tree, and to act as a rudder while gliding. Her main diet is insects, pollen, nectar and seeds. She is highly active and social, living in groups of up to 30 individuals. Often multiple mothers will share the same nest - usually a tree hollow or nest box - and even care for each other's joeys. By sharing the nest, the Feathertails also share their body heat, keeping warm on cooler nights.
