BIRDS nests of ground sparrows arc especially well hidden among the grass or weeds, and one may almost step on such before the bird will fly off and be seen, and even then the nest may not be easily found. Probably for greater safety from weasels, foxes, snakes, and other foes the birds first took to building in trees and bushes. Most such nests are perched in the crotch of a tree or shrub, although some, like the humming-bird and some- times the robin, will saddle the nest on top of a twig or a bough. Some, like the vireos and orioles, suspend their nests from the branches. Among tree dwellers we find some hawks, owls, and eagles, the crow, mourning dove, robin, kingbird, blucjay, blackbird, grosbeak, cedarbird, wood thrush, catbird, many war- blers, and some sparrows. Some birds seem to prefer special kinds of trees. The robin has a hking for box-elders and maples, and the oriole a fondness for the drooping branches of the elm. Most song birds use small twigs, grass, fine fibrous roots, bark fibre, and hair for the material of the nest. Many plaster this material together with mud or clay. This is seen well in the robin's, the phoebe's, and the eaves-swallow's. Fig. (Hair and fiVire in tS.
