Squirrels often build more than one in a season, as reserve nests, lest the primary drey be disturbed by predators or overrun by fleas or lice. Some dreys have been observed in use for more than a decade by multiple generations of squirrels, although the average drey may be used only a year or two before being abandoned. If used repeatedly ...

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.
The eastern gray squirrel is one of very few mammalian species that can descend a tree head-first. It does this by turning its feet so the claws of its hind paws are backward-pointing and can grip the tree bark. [37] [38] Eastern gray squirrels build a type of nest, known as a drey, in
[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 is a flexible sac with a small, round entrance on top, suspended low in a gorse or bramble bush. The structural stability of the nest is provided by a ...

Northern flying squirrels generally nest in holes in trees, preferring large-diameter trunks and dead trees, and will also build outside leaf nests called dreys and will also nest underground. Tree cavities created by woodpeckers as suitable nest sites tend to be more abundant in old-growth forests , and so do the squirrels, though harvested ...
