Did you know that a squirrel can build a nest in just one day?
A mother squirrel will begin to build her nest by loosely weaving twigs together to make the floor. She will create more stability by packing damp leaves and moss
on top of the twig platform to reinforce the structure. Squirrels will use soft materials to line the nest, such as moss, feathers, grass, leaves, shredded bark and pine needles. Then she will use twigs to weave a round frame around the base, which will create the outer wall of the nest.
Both male and female gray squirrels of all ages will participate in building nests. These adorable little creatures will typically build leaf nests (also called dreys) in the summer by weaving together
small branches they’ve gnawed off of trees. These nests are lined with
grass, moss, leaves and pine needles. Some squirrels will even use plastic bags and other man-made items for their nest. Squirrels will return to the same nest every year. However, if the nest is disturbed by
predators or becomes infested with fleas or mites, the squirrel will abandon the nest and built a new home in a different location.
Squirrels will typically build more than one nest, one for the summer and one for the winter. When cold weather arrives, they will abandon their summer drey in favor of a thicker nest which was built in a warmer area such as your attic.
