黃河中游的三門(mén)峽濕地，是野生大天鵝重要的越冬棲息地。每年吸引一萬(wàn)余只越冬的大天鵝。一只雌性大天鵝“美峽”翅膀受傷，不得不永久留在越冬地。在這里，它與另一只受傷的天鵝組建家庭并孵化出了7只幼崽，這是野生大天鵝在黃河流域越冬地自然繁殖成功的首例。隨后的五個(gè)月里，美峽先后失去丈夫和一個(gè)孩子，家庭遭受巨大變故。單親母親困難重重。秋末，大天鵝陸續(xù)抵達(dá)黃河中游的越冬地。美峽的領(lǐng)地也受到了挑戰(zhàn)。第二年春季，越冬的天鵝開(kāi)始飛回北方繁殖地。面對(duì)遷徙，六個(gè)孩子又將何去何從呢？"AfemaleswanMeixia,whosewingswereinjuredandcouldnotfly,hadtostaypermanentlyinthewinteringgrounds,wheresheandanotherwoundedswanfellinlove,thenstartedtobreedandreartheiryoung.However,Meixialostherhusbandandonechildsequentiallyinfivemonths,thesinglemothersuffereddeeplyfromherfamilylostandlifebristledwithdifficultiesforherunexpectedly.Attheendofautumn,thewinteringgroundintheYellowRiverBasiniscrowdedwithotherswanswhichmeansMeixia’sterritoryisfacingchallenge.Nextyearspring,swansareflyingbacktotheirbreedinggrounds.Whenfacingmigration,whatwillbethedestinyofhersixchildren?"bbb
