All types of squirrels are predominantly diurnal. They feed mainly on nuts and other seeds, fruits and other parts of plants and, more rarely, opportunistically on carnal food such as insects, eggs and chicks and other small animals. As tree dwellers, they are very good climbers and most species spend most of their time in the trees and only occasionally come to the ground to forage. They usually build their nests Kobel or Kogel in the form of a spherical structure made of branches and leaves in tree hollows or forks of branches.
The predators of the squirrels are primarily birds of prey and predators such as martens and cats, especially in South America also snakes. Individual specimens of certain species of squirrel can live up to twelve years.
