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").
A western gray squirrel eating pine seeds from a pine cone. Squirrel nests are called dreys and can be seen in trees, built from sticks and leaves wrapped with long strands of grass. There are two stick nest types made by the western gray squirrel: the first is a large, round, covered shelter nest for winter use, birthing, and rearing young.
Eastern gray squirrels are crepuscular, [24] or more active during the early and late hours of the day, and tend to avoid the heat in the middle of a summer day. [40] They do not hibernate. [41] Eastern gray squirrels can breed twice a year, but younger and less experienced mothers normally have a single litter per year in the spring.
[7] [8] [9] A squirrel nest is called a "drey". Squirrels are a serious fire hazard when they break into buildings. They often treat exposed power cables as tree branches, and gnaw on the electrical insulation. The resulting exposed conductors can short out, causing a fire. For this reason alone, squirrel nests inside buildings cannot be safely ...
The nest burrows are for reproducing and raising young; they are usually 5–11 cm deep in well-drained soil with the nest resting at the deepest part of the burrow. [8] The auxiliary burrows do not contain nests; they are less than 50 cm, built 100m from nest burrows, and are constructed in shallow soils. [ 8 ]
The process of building such structures may involve learning and communication, [4] and in some cases, even aesthetics. [5] Tool use may also be involved in building structures by animals.

The Mexican gray squirrel (Sciurus aureogaster), from southern Mexico and Guatemala; introduced into the Florida Keys Index of animals with the same common name This page is an index of articles on animal species (or higher taxonomic groups) with the same common name ( vernacular name).
These squirrels have been observed in mating chases with many males chasing one female. [4] An important conservation strategy for the survival of the Arizona gray squirrel is to protect their nesting habitat. This means maintaining large trees with closed canopies that allow access to resources and protection from predators. [4]
