Animals and plants are taught by Wakan tanka what they are to do. Wakan tanka teaches the birds to make nests, yet the nests of all birds are not alike. Wakan tanka gives them merely the outline. Some make better nests than others. In the same way some animals are satisfied with very rough dwellings, while others make attractive places in which to live.
Some animals also take better care of their young than others.
The forest is the home of many birds and other animals, and the water is the home of fish and reptiles. All birds, even those of the same species, are not alike, and it is the same with animals and with human beings. The reason Wakan tanka does not make two birds, or animals, or human beings exactly alike is because each is placed here by Wakan tanka to be an independent individuality and to rely on itself.
