Snug as a squirrel

Shhh, it’s sleeping. But don’t confuse that with hibernating. A tree squirrel, like this red squirrel in the Scottish Highlands, doesn’t hibernate during the winter. But it is particular about where it sleeps, mostly building its nest, or drey, high above the ground in holes in evergreen trees. Nests are often lined with soft materials like leaves, moss and grass. This little sleeper is using its bushy tail to keep warm, with the help of some lichen and pine needles.
