Abstract:

I-Bohai Black-tailed Godwit (Limosa limosa bohaii) iwuhlobo olusanda kutholwa e-East Asian-Australasian Flyway. Ngokusekelwe ekulandeleleni ngesathelayithi kwabantu abangu-21 ababemakwe enyakatho ye-Bohai Bay, e-China, kusukela ngo-2016 kuya ku-2018, lapha sichaza umjikelezo waminyaka yonke walezi zinhlobo ezincane. Zonke izinyoni zazineThailand njengendawo yazo eseningizimu 'ebusika'. Ukuhamba kwentwasahlobo kwaba ngasekupheleni kukaMashi ngesikhathi sokufudukela enyakatho, i-Bohai Bay kwaba yindawo yokuqala yokuma lapho bachitha khona ngokwesilinganiso izinsuku ezingama-39 (± SD = 6 d), kulandele i-Inner Mongolia nesifundazwe saseJilin (imisa i-8 d ± 1 d). Ukufika kwezindawo zokuzalela eMpumalanga Ekude yaseRussia kwakugxile ekupheleni kukaMeyi. Kutholwe izindawo ezimbili ezizalela kuzo, ezinezindawo eziqhelelene ngamakhilomitha ayi-1100; indawo esempumalanga yayingaphezu kokusabalalisa kwe-Black-tailed Godwit okwaziwayo e-Asia. Ukufudukela eningizimu kwaqala ngasekupheleni kukaJuni, lapho ama-godwit ejwayele ukuma isikhathi eside ezindaweni ezimbili ezifanayo zokuma ezisetshenziswa entwasahlobo, okungukuthi isifunda sase-Inner Mongolia neseJilin (32 ± 5 d) kanye ne-Bohai Bay (44 ± 8 d), abanye abantu benza isitobhi sesithathu ezindaweni ezimaphakathi nezansi zoMfula i-Yangtze 4d eningizimu yeChina (1d ± 2). Ekupheleni kukaSepthemba, abantu abaningi ababelandelwa umkhondo base befikile eThailand. Uma kuqhathaniswa nezinhlobo ezingaphansi ezaziwayo ngaphambilini, ama-bohaii godwit aneshejuli ehluke ngokumangalisayo yokufuduka ne-moult, lolu cwaningo ngaleyo ndlela lwengeza olwazini mayelana nokuhlukahluka okukhethekile kwama-black-tailed godwit e-East Asian-Australian Flyway.
