Soo Koobid:

Caddeymo ayaa tilmaamaya in shimbiraha biyaha ee jiilaalka ay si cad ugu urureen laba haro oo ugu waaweyn daadadka Webiga Yangtze, Bariga Dong Ting Lake (Gobolka Hunan, 29°20′N, 113°E) iyo Poyang Lake (Gobolka Jiangxi, 29°N, 116°20′E), marka loo eego harooyinka kale, inkastoo meelo kale laga sameeyay kayd. In kasta oo xiriirkani uu u badan yahay inuu sabab u yahay baaxad weyn oo ah deegaanno aan la carqaladeyn oo ku yaal harooyinka waaweyn, haddana wax yar ayaan ka fahannay darawallada saameeya dhaqanka shaqsiga ah ee ka dambeeya u janjeersigan. Waxaan la soconay dhaqdhaqaaqa jiilaalka ee saddex nooc oo shimbiro ah (Eurasian Wigeon Mareca penelope, Falcated Duck M. falcata iyo Northern Pintail Anas acuta) annagoo adeegsanayna qalabka gudbinta GPS-ka, annagoo baareynayna farqiga u dhexeeya labada haro ee ugu waaweyn iyo harooyinka kale ee yaryar ee isticmaalka deegaanka shimbiraha, muddada ay joogaan haro kasta iyo masaafada maalinlaha ah ee ay u dhaqaaqaan shimbiraha calaamadaysan inta ay joogaan goobahan. Eurasian Wigeon iyo Falcated Duck waxay joogeen shan jeer oo dheer waxayna si gaar ah u isticmaali jireen noocyada deegaanka dabiiciga ah ee labada haro ee waaweyn (91% booska) marka la barbar dhigo muddada joogitaanka harooyinka yaryar, halkaas oo ay ku qaateen celcelis ahaan 28-33 maalmood (marka laga reebo goobta la qabtay) waxayna ka faa'iideysteen deegaanno badan oo kala duwan (oo ay ku jiraan qiyaastii 50% harooyinka dibadda). Daraasaddeennu waa tii ugu horreysay ee muujisa in muddada gaaban ee joogitaanka iyo isticmaalka deegaanka ee shimbiraha ee harooyinka yaryar ay gacan ka geysan karaan sharraxaadda tirada muuqata ee gobolka ee noocyadan iyo noocyada kale ee harooyinka ugu waaweyn sannadihii ugu dambeeyay. Tani waxay la barbar dhigaysaa tirada sii yaraanaysa ee harooyinka yaryar, halkaas oo khasaaraha deegaanka iyo burburku ay aad uga muuqdaan harooyinka waaweyn.
