Inkcazo:
Iindawo zokuhlala zibonelela ngesithuba esiyimfuneko kwiintaka ezifudukayo ukuze ziphile kwaye zizala. Ukuchonga iindawo zokuhlala ezinokubakho kwizigaba zomjikelo wonyaka kunye neempembelelo zazo ezibalulekileyo kulondolozo olusecaleni kwendlela. Kolu phononongo, sifumene umkhondo wesathelayithi wamarhanisi asibhozo (Anser cygnoides) ebusika e-Poyang Lake (28°57′4.2″, 116°21′53.36″) ukusuka ngo-2019 ukuya ku-2020. ukusasazwa kweendawo zokuhlala ezinokubakho zamarhanisi ngexesha lomjikelo wawo wokufuduka. Sihlalutye igalelo elinxulumeneyo lemiba eyahlukeneyo yokusingqongileyo ukufaneleka kwendawo yokuhlala kunye newonga lolondolozo lwekhaya ngalinye elinokubakho ecaleni kwendlela yokubhabha. Iziphumo zethu zibonisa ukuba iindawo zasebusika zamarhanisi zimi kumbindi nasezantsi woMlambo iYangtze. Iindawo zokumisa ziye zasasazwa ngokubanzi, ngakumbi kwi-Bohai Rim, indawo ephakathi yoMlambo oMthubi, kunye neThafa elikuMntla-mpuma, kwaye zandiswa ngasentshona ukuya kwi-Inner Mongolia kunye neMongolia. Iindawo zokuzalela ikakhulu kwi-Inner Mongolia nakwimpuma yeMongolia, ngelixa ezinye zithe saa kumbindi weMongolia nasentshona. Amazinga egalelo leemeko eziphambili zokusingqongileyo ahlukile kwiindawo zokuzalela, iindawo zokumisa, kunye neendawo zasebusika. Iindawo ezizalela kuzo zaziphenjelelwa kukuthambeka, ukuphakama nobushushu. Ukuthambeka, isalathisi somntu, kunye nobushushu bezezona zinto zichaphazela iindawo zokumisa. Iindawo zasebusika zazimiselwa ngokusetyenziswa komhlaba, ukuphakama, kunye nemvula. Imo yolondolozo lweendawo zokuhlala yi-9.6% yeendawo zokuzala, i-9.2% yeendawo zobusika, kunye ne-5.3% yeendawo zokumisa. Iziphumo zethu ke ngoko zibonelela ngovavanyo oluhlabayo lwamazwe ngamazwe lokhuseleko lweendawo zokuhlala ezinokubakho kwiintlobo zamarhanisi kwi-East Asian Flyway.
