 <unk> . These birds are so called because they always go alone . They are the size of a large Goose , and are white , with the tips of the wings and tail black . The tail feathers resemble those of an <unk> ; the neck is long , and the beak is like that of a <unk> , but larger ; the legs and feet like those of <unk> . This bird has recourse to running , as it flies but very little .
