Where do ostriches nest?

We all know that birds build nests. Some find trees the most convenient. Others prefer hedges, the eaves of roofs, chimney pots, rocky ledges or holes in trees. But what does a bird do that can neither fly nor swim? Living on the dry, open plains of eastern and southern Africa, the ostrich takes no pains to hide its nest. It merely finds a suitable shallow depression in the ground, which it may scoop out further with its feet. The hole may be up to three yards across. In it are laid six to eight eggs, each one by a different female. Then one hen and one cock take turns guarding the two and a half pound eggs until they are ready to hatch.
