Izinhlobo (Izinyoni):I-Whimbrel (Numenius phaeopus)

Ijenali:Ucwaningo Lwezinyoni

Abstract:

Ukunquma imizila yokufuduka kanye nokuxhumana kwezinyoni ezifudukayo ezingeni labantu kusiza ukucacisa umehluko ongaphakathi kwe-intraspecific ekufudukeni. Izinhlobo ezinhlanu ezingaphansi ziye zaqashelwa ku-Whimbrel (Numenius phaeopus) e-Eurasia. Ssp. i-rogachevae yi-subspecies echazwe kamuva nje. Izalela eCentral Siberia, kanti isifunda sayo esingazaleli nezindlela zokufuduka azikacaci. Silandelele ukufuduka kwama-Eurasian Whimbrels athathwe ezindaweni ezintathu ezingazaleli (i-Moreton Bay ogwini olusempumalanga ye-Australia, i-Roebuck Bay eNyakatho-ntshonalanga ye-Australia kanye ne-Sungei Buloh Wetland e-Singapore) kanye nezindawo ezimbili zokumisa ukufuduka (i-Chongming Dongtan ne-Mai Po Wetland e-China). Sinqume iziza zokuzalela futhi sabonisa izinhlobo ezingaphansi zezinyoni ezimakiwe e-East Asian - Australasian Flyway (EAAF) ngokusekelwe ekusabalaliseni okwaziwayo kokuzalanisa kwezinhlobo ezincane ngazinye. Kulezi zinyoni ezimakiwe ezingu-30, izinyoni ezingu-6 nezingu-21 zizalela ezinhlobonhlobo ze-ssp. rogachevae kanye variegatus, ngokulandelana; eyodwa izalwa endaweni okucatshangwa ukuthi ishintsha phakathi kohlu lokuzalanisa lwe-ssp. i-phaeopus ne-rogachevae, kanye nezimbili ezifuywe endaweni phakathi kohlu lokuzalanisa lwe-ssp. rogachevae futhi variegatus. Izinyoni ezazalela e-ssp. Uhlu lokuzalanisa i-rogachevae lwachitha isikhathi sawo sokungazaleli enyakatho yeSumatra, Singapore, East Java kanye naseNyakatho-ntshonalanga ye-Australia futhi ikakhulukazi yama ngasogwini lwaseShayina ngesikhathi sokufuduka. Azikho izinyoni zethu ezazalanisa ngokukhethekile i-phaeopus subspecies. Ucwaningo lwangaphambilini lubikezele ukuthi ama-rogachevae whimbrel afuduka eduze kwe-Central Asian Flyway futhi achithe inkathi yokungazali eNtshonalanga India naseMpumalanga Afrika. Sithole ukuthi okungenani amanye ama-rogachevae whimbrel afuduka eduze kwe-EAAF futhi achithe isikhathi esingazalisi eNingizimu-mpumalanga ye-Asia nase-Australia. I-ssp. I-phaeopus isatshalaliswa ngokuncane kakhulu ku-EAAF esifundeni esisentshonalanga, noma kungenzeka ingenzeki nhlobo.
