Isifinyezo:
I-Great Bustard (Otis tarda) iphethe umehluko phakathi kwenyoni esindayo kakhulu ukufuduka kanye nezinga elikhulu kakhulu lokwehluka kobukhulu bobulili phakathi kwezinyoni eziphilayo. Nakuba ukufuduka kwalolu hlobo kuye kwaxoxwa kabanzi ezincwadini, abacwaningi abazi lutho ngamaphethini okufuduka kwalolu hlobo e-Asia (Otis tarda dybowskii), ikakhulukazi abesilisa. Ngo-2018 nango-2019, sabamba ama-O. t. dybowskii ayisithupha (abesilisa abahlanu kanye nensikazi eyodwa) ezindaweni zabo zokuzalela empumalanga yeMongolia futhi sawamaka ngama-transmitter esathelayithi se-GPS-GSM. Lokhu kungokokuqala ukuthi ama-Great Bustard alolu hlobo lwasempumalanga alandelwe empumalanga yeMongolia. Sithole umehluko wobulili emaphethini okufuduka: abesilisa baqala ukufuduka kamuva kodwa bafika ngaphambi kwensikazi entwasahlobo; abesilisa babene-1/3 yesikhathi sokufuduka futhi bathuthela cishe i-1/2 yebanga lensikazi. Ngaphezu kwalokho, ama-Great Bustard abonise ukwethembeka okuphezulu ezindaweni zawo zokuzalela, ngemva kokuzalela kanye nezindawo zokuhlala ebusika. Ngokulondolozwa kwemvelo, u-22.51% kuphela wokulungiswa kwendawo ye-GPS yama-bustard ayesezindaweni ezivikelwe, futhi angaphansi kuka-5.0% ezindaweni zasebusika kanye nangesikhathi sokufuduka. Phakathi neminyaka emibili, ingxenye yama-Great Bustard esasiwalandelela yafa ezindaweni zayo zasebusika noma ngesikhathi sokufuduka. Sincoma ukusungula izindawo ezivikelwe kakhulu ezindaweni zasebusika kanye nokushintsha umzila noma ukufaka izintambo zikagesi ngaphansi komhlaba ezindaweni lapho ama-Great Bustard esakazeke khona kakhulu ukuze kuqedwe ukushayisana.
