Ibisobanuro:
Ibimenyetso byerekana ko inyoni zo mu mazi zimbeho zimaze kwibanda cyane ku biyaga bibiri binini by’Umugezi w’Umugezi wa Yangtze, Ikiyaga cya Dong Ting (Intara ya Hunan, 29 ° 20′N, 113 ° E) n’ikiyaga cya Poyang (Intara ya Jiangxi, 29 ° N, 116 ° 20′E), ugereranije n’ibindi biyaga, nubwo hashyizweho ibigega. Mugihe iyi mibanire ishobora kuba iterwa nubwinshi bwimiturire idahungabanye mubiyaga binini, ntitwumva bike mubashoferi bigira ingaruka kumyitwarire yabantu inyuma yiyi myumvire. Twakurikiranye ingendo yimbeho yubwoko butatu bwimbwa (Eurasian Wigeon Mareca penelope, Falcated Duck M. falcata na Pintail Anas acuta y'Amajyaruguru) dukoresheje imiyoboro ya GPS, dusuzuma itandukaniro riri hagati y’ibiyaga binini binini n’ibindi biyaga bito mu mikoreshereze y’imbwa, igihe cyo kuguma kuri buri kiyaga n’intera ya buri munsi yimurwa n’inyoni zashizweho igihe ziri kuri ibyo bibanza. Inuma ya Eurasian Wigeon na Falcated Duck yagumye inshuro eshanu kandi hafi ya yose yakoresheje ubwoko bwimiterere yabantu kubiyaga binini binini (91‒95% byimyanya) ugereranije nuburebure bwigihe cyo kumara ibiyaga bito, aho bamaranye iminsi 28‒33 mugereranije (usibye aho bafatiwe) bagakoresha ahantu henshi hatandukanye (harimo nka 50% hanze yibiyaga byo hanze). Ubushakashatsi bwacu nubwa mbere bwerekana ko igihe gito cyo kumara no gukoresha ahantu hatandukanye hifashishijwe inkongoro ku biyaga bito bishobora kugira uruhare mu gusobanura ubwinshi bw’akarere k’imibare igaragara muri ubu bwoko n’andi moko ku biyaga binini mu myaka yashize. Ibi ugereranije nubwinshi bwabo bugabanuka kubiyaga bito, aho gutakaza aho gutura no kwangirika byagaragaye cyane kuruta ibiyaga binini.
