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").
The tools allow them to extract large, nutritious insect larvae from tree holes, making tool use more profitable than other foraging techniques. In contrast, in the humid zone, woodpecker finches rarely use tools, since food availability is high and prey is more easily obtainable.
At night, territorial family groups nest together in holes in trees. Offspring become sexually mature between six and nine months old, when they are forcibly evicted by the breeding pair . The males are mainly responsible for territorial defense, although females also chase intruders when they care for dependent pups.
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 ...
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.
“A recent discovery of a tree-hole-living species in Taiwan was therefore surprising.” The Taiwanese tree-dwelling wolf spider is considered “large,” reaching about 0.8 inches in size, the ...
The squirrel makes a drey (nest) out of twigs in a branch-fork, forming a domed structure about 25–30 cm (9.8–11.8 in) in diameter. This is lined with moss, leaves, grass and bark. Tree hollows and woodpecker holes are also used. The red squirrel is a solitary animal and is shy and reluctant to share food with others.
Douglas squirrels are active by day, throughout the year, often chattering noisily at intruders. On summer nights, they sleep in ball-shaped nests that they make in the trees, but in the winter they use holes in trees as nests. Groups of squirrels seen together during the summer are likely to be juveniles from a single litter.
