The forest margins, which make a transition zone between the two, are richer than either. Under these conditions the advantages of both communities are availa- ble and their disadvantages are The forest furnishes a hiding place for terrestrial mammals during the day and a resting Fig. 117.—Deposition of eggs by Cochlostyla leucophthalma.

In the continuous primeval forests of the North Temperate Zone, such ani- mals as the deer and the wolf are practically limited to a belt 5-8 km. wide near the forest In Java, deer, wild boar, and leopard lie concealed in thickets during the day and feed in the open at The forests that border the African grasslands afford food and shelter during the dry season for antelope, buffalo, rhinoceros, and elephants. The flying foxes (Pterojms) sleep among the forest trees and fly out in search of food. This is a common habit among birds which can range far from their sleeping places in search of food. Isolated forest islands in the Asiatic steppe are crowded with the nests of eagles, falcons, rooks, and other birds which feed on the The forest is a refuge for man as it is for the other animals.
