 The Combats between them on this occasion last sometimes pretty long , because the Stranger only turns about , and do 's not fly directly from the Nest . However , the others do not forsake it till they have quite driven it out of their Limits . After these Birds have rais 'd their young One , and left it to itself , they are always together , which the other Birds are not , and tho ' they happen to mingle with other Birds of the same Species , these two Companions never disunite . We have often remark 'd , that some Days after the young leaves the Nest , a Company of thirty or forty brings another young one to it , and the now fledg 'd Bird , with its Father and Mother joyning with the Band , march to some bye Place . We frequently follow 'd them , and found that afterwards the old ones went each their way alone , or in Couples , and left the two young ones together , which we call 'd a Marriage .
