Kakaretso:
Bopaki bo fana ka maikutlo a hore linonyana tsa metsing tse lulang mariha li se li le matšeng a mabeli a maholohali a Nōka ea Moroallo ea Yangtze, East Dong Ting Lake (Profinseng ea Hunan, 29°20′N, 113°E) le Letša la Poyang (Profinseng ea Jiangxi, 29°N, 116°20′E), ho sa tsotellehe libaka tse ling tsa matša. Le hoja kamano ena e ka 'na ea bakoa ke sebaka se seholo sa libaka tse sa khathatsoang matšeng a maholoanyane, re utloisisa tse fokolang tsa bakhanni ba amang boitšoaro ba motho ka mong. Re ile ra latela metsamao ea mariha ea mefuta e meraro ea matata (Eurasian Wigeon Mareca penelope, Falcated Duck M. falcata le Northern Pintail Anas acuta) re sebelisa li-transmitters tsa GPS, ho hlahloba phapang lipakeng tsa matša a mabeli a maholo le matša a mang a manyane a sebelisoang sebakeng sa matata, nako ea ho lula letšeng le leng le le leng le libaka tse hole le linonyana tse tsamaeang letsatsi le letsatsi.
