 These animals on our coming up to them stared at us and remained quiet where they stand , not knowing whether they had wings to fly away or legs to run off , and suffering us to approach them as close as we pleased . Amongst these birds were those which in India they call Dod @-@ aersen ( being a kind of very big goose ) ; these birds are unable to fly , and instead of wings , they merely have a few small pins , yet they can run very swiftly . We drove them together into one place in such a manner that we could catch them with our hands , and when we held one of them by its leg , and that upon this it made a great noise , the others all on a sudden came running as fast as they could to its assistance , and by which they were caught and made prisoners also .
