Squirrels spend 70% ~ 80% of their time foraging and tend to forage and store food in coniferous forests. In autumn, squirrels scatter nuts on the ground and store fungi on branches. Storage in autumn is beneficial to the overwintering and reproduction of squirrels in the next year. The selection of storage micro-habitat and storage retrieval mechanism of squirrels have been deeply studied, which has become a hot spot in squirrel ecology research in China.

Squirrel habits:
Squirrels have very long ears and tails, which can adapt to life in trees; They hang upside down from the branches with claws and tails like long hooks. At dawn and evening, they also leave the trees and hunt on the ground. After finding abundant food in autumn, squirrels will use tree holes or dig holes in the ground to store fruits and other foods, and at the same time block the holes with dirt or fallen leaves.
Squirrels nest in dense branches, or use abandoned nests of crows and magpies, and sometimes nest in tree holes; They eat not only wild fruits, but also twigs, buds, leaves, insects and eggs. As soon as autumn comes, squirrels begin to store food. A squirrel often stores several kilograms of food in several places, and sometimes he can see the squirrel drying food in the tree.
