Abstract:
I-Far East Greylag Geese engu-20, i-Anser anser rubrirostris, yathathwa yaphinde yafakwa abagawuli bemithi ye-Global Positioning System/Global System for Mobile Communications (GPS/GSM) ukuze kuhlonzwe izindawo zokuzalanisa nezobusika, imizila yokufuduka kanye nezindawo zokuma. Idatha ye-Telemetry okokuqala ngqa ibonise ukuxhumana phakathi kwezindawo zabo zasebusika zoMfula i-Yangtze, izindawo zokuma enyakatho-mpumalanga ye-China, kanye nezindawo zokuzalela/zokuncibilika empumalanga yeMongolia nasenyakatho-mpumalanga ye-China. Abantu abamakiwe abangu-10 kwabangu-20 banikeze idatha eyanele. Bama lapho befuduka e-Yellow River Estuary, Beidagang Reservoir kanye ne-Xar Moron River, beqinisekisa lezi zindawo njengezindawo ezibalulekile zokuma kulaba bantu. Isikhathi esimaphakathi sokufuduka kwentwasahlobo kwakuyizinsuku ezingama-33.7 (abantu baqale ukufuduka phakathi kuka-25 February kanye no-16 Mashi futhi baqeda ukufuduka kusukela ku-1 kuya ku-9 April) uma kuqhathaniswa nezinsuku ezingu-52.7 ekwindla (26 Septhemba-13 October kuze kube ngu-4 November-11 December). Ubude besikhathi sokuma obumaphakathi kwakuyizinsuku ezingu-31.1 nezingu-51.3 kanti isivinini esimaphakathi sohambo sasingu-62.6 kanye no-47.9 km/ngosuku ngokufuduka kwentwasahlobo nasekwindla, ngokulandelana. Umehluko obalulekile phakathi kokufuduka kwentwasahlobo nekwindla ngesikhathi sokufuduka, ubude besikhathi sokuma kanye nesivinini sokufuduka kuqinisekisile ukuthi amahansi ama-Greylag amahansi ahamba ngokushesha entwasahlobo kunekwindla, asekela umbono wokuthi kufanele akhawulelwe isikhathi esiningi phakathi nokufuduka kwentwasahlobo.
