Iintlobo (zeentaka):I-Greylag goose okanye i-graylag goose (I-Anser anser)
Isishwankathelo:
Iirhanisi ezingama-20 zaseMpuma Ekude iGreylag, iAnser anser rubrirostris, zabanjwa zaza zafakelwa iilogger zeGlobal Positioning System/Global System for Mobile Communications (GPS/GSM) ukuze zichonge iindawo zokuzalela nezokuhlala ebusika, iindlela zokufuduka kunye neendawo zokuma. Idatha yeTelemetry okokuqala ibonise unxibelelwano phakathi kweendawo zabo zasebusika zoMlambo iYangtze, iindawo zokuma kumntla-mpuma weTshayina, kunye neendawo zokuzalela/zokunyibilika empuma yeMongolia nakumntla-mpuma weTshayina. I-10 kwezingama-20 eziphawulwe ngabantu zinike idatha eyaneleyo. Baye bayeka ukufuduka kwiYellow River Estuary, eBeidagang Reservoir naseXar Moron River, beqinisekisa ezi ndawo njengeendawo ezibalulekileyo zokuma kweli nani. Ubude obuphakathi bokufuduka kwentwasahlobo yayiziintsuku ezingama-33.7 (abantu baqale ukufuduka phakathi komhla wama-25 kuFebruwari nowe-16 kuMatshi baza bagqiba ukufuduka ukusuka ngomhla woku-1 ukuya kowe-9 ku-Epreli) xa kuthelekiswa neentsuku ezingama-52.7 ekwindla (26 Septemba-13 Okthobha ukuya kuthi ga ngomhla wesi-4 kuNovemba-11 kuDisemba). Ixesha eliphakathi lokuma laliziintsuku ezingama-31.1 kunye nama-51.3 kwaye isantya esiphakathi sokuhamba sasiyi-62.6 kunye ne-47.9 km/ngosuku lokufuduka kwentwasahlobo kunye nekwindla, ngokulandelelana. Umahluko obalulekileyo phakathi kokufuduka kwentwasahlobo kunye nekwindla kwixesha lokufuduka, ixesha lokuma kunye nesantya sokufuduka kuqinisekisile ukuba iGreylag Geese yabantu abadala bahamba ngokukhawuleza entwasahlobo kunekwindla, ixhasa ingcamango yokuba kufuneka banqunyelwe ixesha elingakumbi ngexesha lokufuduka kwentwasahlobo.
