Drey
A drey is the nest of a tree squirrel, flying squirrel or ringtail possum. Dreys are usually built of leaves and twigs, and typically assembled in the forks of a tall tree. They are sometimes referred to as "drey nests" to distinguish them from squirrel "cavity nests". In temperate regions, dreys become much more visible in the autumn, when leaf-fall reveals new nests built the previous summer or in early fall.
