Caddaynta ayaa soo jeedinaysa in shimbiraha jiilaalka ay noqdeen kuwo si aad ah ugu urursan labada haro ee ugu waaweyn Wabiga Yangtze ee Fatahaadda, Harada Bari ee Dong Ting (Gobolka Hunan, 29°20′N, 113°E) iyo Poyang Lake (Gobolka Jiangxi, 29°N, 116°20′E) Inkasta oo xidhiidhkani uu u badan yahay in ay sabab u tahay baaxad weyn oo ah degaannada aan qasnayn ee harooyinka waaweyn, waxaan fahamsanahay wax yar oo ka mid ah darawallada saameeya dabeecadaha shakhsi ahaaneed ee ka dambeeya dareenkan. Waxaan la soconnay dhaqdhaqaaqyada jiilaalka ee saddexda nooc ee shinbiraha (Eurasian Wigeon Mareca penelope, Falcated Duck M. falcata iyo Northern Pintail Anas acuta) anagoo adeegsanayna gudbinta GPS-ka, baaritaanka kala duwanaanshaha u dhexeeya labada harooyin ee ugu waaweyn iyo harooyinka kale ee yaryar ee isticmaalka deegaanka shinbiraha, muddada joogitaanka haro kasta iyo masaafada maalinlaha ah ee ay dhaqaaqaan shimbiraha calaamadeysan halka ay ku sugan yihiin. Eurasian Wigeon iyo Duck Falcated waxay joogeen shan jeer dheer waxayna ku dhawaad ​​​​si gaar ah u isticmaaleen noocyada deegaanka dabiiciga ah ee labada haro ee waaweyn (91-95% boosaska) marka la barbar dhigo dhererka waqtiga joogitaanka harooyinka yaryar, halkaas oo ay ku qaateen 28-33 maalmood celcelis ahaan (marka laga reebo goobta qabashada) waxayna ka faa'iideysteen degaanno badan oo kala duwan (oo ay ku jiraan 50% harooyinka dibadda). Daraasaddeenu waa tii ugu horreysay ee muujinaysa in dhererka gaaban ee joogitaanka iyo isticmaalka badan ee deegaanka ee isticmaalka shinbiraha ee harooyinka yaryar ay gacan ka geysan karaan sharraxaadda tirada gobollada ee muuqata ee tirooyinkan iyo noocyada kale ee harooyinka ugu waaweyn sannadihii la soo dhaafay. Tani waxay barbar dhigaysaa hoos u dhaca badankooda ee harooyinka yaryar, halkaas oo khasaaraha iyo nabaad-guurka deegaanku ay aad uga soo shaac baxeen harooyinka waaweyn.
