A drey is the nest of a tree squirrel, flying squirrel or ringtail possum. [1] Dreys are usually built of twigs, dry leaves, and grass, and typically assembled in the forks of a tall tree. [2] They are sometimes referred to as "drey nests" to distinguish them from squirrel "cavity nests" (also termed "dens").
In Norse mythology, the squirrel Ratatoskr is a messenger who scurries up and down the trunk of the world-tree Yggdrasil, carrying malicious gossip and insults back and forth between the dragon Níðhöggr, who sits at the bottom of the tree gnawing on its roots, and the hawk Veðrfölnir, who sits at the top of the tree keeping watch.

[10] Nests are built in trees occurring as part of a grouping of trees with interlocking crowns.
