Ukuchongwa kweendawo zokuzalela kunye neenkqubo zonyaka zeentlobo ezisandula ukufunyanwa ze-bohaii ze-Black-tailed Godwits.

Iintlobo (zeentaka):I-Black-tailed Godwit (iLimosa limosa bohaii)

Ijenali:I-Emu

Isishwankathelo:

I-Bohai Black-tailed Godwit (iLimosa limosa bohaii) yintlobo esandul’ ukufunyanwa kwi-East Asian-Australasian Flyway. Ngokusekelwe ekulandeleni ngesathelayithi izilwanyana ezingama-21 ezaziphawulwe kumantla eBohai Bay, eTshayina, ukususela ngo-2016 ukuya ku-2018, apha sichaza umjikelo wonyaka wale ntlobo. Zonke iintaka zazineThailand njengendawo yazo 'yobusika' emazantsi. Ukuhamba kwentwasahlobo kwakusekupheleni kukaMatshi ngexesha lokufuduka ukuya emantla, iBohai Bay yayiyindawo yokuqala yokuma apho zachitha khona umyinge weentsuku ezingama-39 (± SD = 6 ngosuku), zilandelwa yi-Inner Mongolia kunye nephondo laseJilin (zimisa iintsuku ezisi-8 ngosuku ± 1 ngosuku). Ukufika kweendawo zokuzalela kwiMpuma Ekude yaseRashiya kwakuphakathi ekupheleni kukaMeyi. Iindawo ezimbini zokuzalela zafunyanwa, kunye neendawo eziphakathi kwe-1100 km ukusuka kwenye; indawo esempuma yayingaphaya kokusasazwa kwezityalo zaseAsia zeBlack-tailed Godwit. Ukufuduka ukuya emazantsi kwaqala ngasekupheleni kukaJuni, apho ii-godwits ziqhele ukuma ixesha elide kwiindawo ezimbini eziphambili zokuma ezisetyenziswa entwasahlobo, oko kukuthi, i-Inner Mongolia kunye nephondo laseJilin (32 ± 5 d) kunye neBohai Bay (44 ± 8 d), kunye nezinye izilwanyana ezenza ukuma kwesithathu kwiindawo eziphakathi ezisezantsi zoMlambo iYangtze kumazantsi eTshayina (12 ± 4 d). Ekupheleni kukaSeptemba, uninzi lwezilwanyana ezilandelelwayo zazisele zifikile eThailand. Xa kuthelekiswa nezinye iintlobo ezazisaziwa ngaphambili, ii-bohaii godwits zineshedyuli eyahlukileyo yokufuduka kunye nokubola, olu phononongo ngaloo ndlela longeza ulwazi malunga nokwahluka kwe-intraspecific kwee-black-tailed godwits kwi-East Asian-Australian Flyway.
