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").
Once established in a nest, squirrels ignore fake owls and scarecrows, along with bright flashing lights, loud noises, and ultrasonic or electromagnetic devices. However, squirrels must leave the nest to obtain food and water (usually daily, except in bad weather), affording an opportunity to trap them or exclude them from re-entering. [7] [9]
Nests were most often built on the southern to southeastern side of the tree. [5] Patton reports that nest trees in Arizona had crowns that were 35% to 55% of the total tree height, and most often were 14 to 16 inches (36 to 41 centimetres) d.b.h. [10] Nests are built in trees occurring as part of a grouping of trees with interlocking crowns.
The fox squirrel (Sciurus niger), also known as the eastern fox squirrel or Bryant's fox squirrel, [3] is the largest species of tree squirrel native to North America. It is sometimes mistaken for the American red squirrel or eastern gray squirrel in areas where the species co-exist , though they differ in size and coloration.
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 ...
This squirrel born without his hind legs is the embodiment of 'thinking on your feet.' A 15-second video has sprung up online showing the arboreal rodent manoeuvring with ease across a driveway on ...
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.
Several squirrels may share a den to help keep them warm. Famously, squirrels will hoard food for the winter. They'll dig a hole, place food inside, and then cover it for the change of season.
