Iintlobo (Intaka):I-Greylag goose okanye i-graylag goose (I-Anser anser)
Inkcazo:
Amashumi amabini e-Far East Greylag Geese, i-Anser anser rubrirostris, yabanjwa yaza yafakelwa i-Global Positioning System/Global System ye-Mobile Communications (GPS/GSM) abagawuli bemithi ukuze bachonge iindawo zokuzalela kunye nobusika, iindlela zokufuduka kunye neendawo zokumisa. Idatha yeTelemetry okokuqala ngqa ibonise unxibelelwano phakathi kweendawo zabo zasebusika zoMlambo iYangtze, iindawo zokumisa kumntla-mpuma weTshayina, kunye neendawo zokufuya/zokunyibilika kwimpuma yeMongolia nakumantla-mpuma eTshayina. I-10 kwabangama-20 abantu abathegiweyo banike idatha eyaneleyo. Bamisa xa befudukela eYellow River Estuary, eBeidagang Reservoir naseXar Moron River, beqinisekisa ezi ndawo njengeziza ezibalulekileyo zokumisa kolu luntu. Ubude bexesha eliphakathi lokufuduka kwentwasahlobo yayiziintsuku ezingama-33.7 (abantu baqale ukufuduka phakathi komhla wama-25 kuFebruwari kunye nowe-16 Matshi baze bagqibezela ukufuduka ukusuka kumhla woku-1 ukuya kowesi-9 kuEpreli) xa kuthelekiswa neentsuku ezingama-52.7 ekwindla (26 Septemba–13 Oktobha de kube ngowe-4 kuNovemba-11 kuDisemba). Ubude bexesha lokumisa eliphakathi laliyi-31.1 kunye neentsuku ze-51.3 kwaye isantya esiphakathi sokuhamba sasiyi-62.6 kunye ne-47.9 km / ngosuku lokufuduka kwentwasahlobo nasekwindla, ngokulandelelanayo. Umahluko obalulekileyo phakathi kokufuduka kwentwasahlobo kunye nekwindla ngexesha lokufuduka, ixesha lokumisa kunye nesantya sokufuduka kuqinisekisile ukuba umntu omdala othegiweyo uGreylag Geese bahambe ngokukhawuleza entwasahlobo kunekwindla, bexhasa uluvo lokuba kufuneka babekelwe ixesha elininzi ngexesha lokufuduka kwentwasahlobo.
