What kind of animals live in nests known as dreys?

Answer: A drey is the nest of a squirrel, usually built of twigs and branches that are typically assembled in the forks of a tall tree. The finished drey is a hollow sphere, about a foot or more in diameter, with branches and other materials loosely woven on the outside and an inner surface lined with a variety of finer materials, such as grass, moss, and leaves. Adult squirrels often build two dreys so they have an option if one is disturbed. The average drey is only used for a year or two before it is abandoned, although remnants of the nest can be visible for years.


A drey – or dray – is a nest of a tree squirrel or a flying squirrel. Dreys are usually built of twigs, dry leaves, and grass, and typically assembled in the forks of a tall tree.[1] They are sometimes referred to as “drey nests” to distinguish them from squirrel “cavity nests” (also termed “dens”). 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.

A favoured site for a drey is a tree crotch about 30 to 45 feet (9.1 to 13.7 m) above ground level. Squirrels may also nest in attics or exterior walls of buildings, where a drey may be regarded as a fire hazard, as some squirrels have a habit of gnawing on electrical cables. At other times, squirrels may inhabit a permanent tree den in the hollow of a trunk or large branch.
