Amaphethini okufuduka kwendawo nesikhathi saminyaka yonke ama-Hooded Cranes ahlala ebusika e-Izumi ngokusekelwe ekulandeleni kwesathelayithi kanye nemiphumela yawo ekulondolozweni.

Izinhlobo (zezinyoni):I-Hooded Crane (i-Grus monacha)

Isifinyezo:

I-Hooded Crane (i-Grus monacha) ibhalwe njengezinhlobo ezisengozini yi-IUCN. Ulwazi mayelana nokufuduka kwe-Hooded Crane lusalinganiselwe. Lapha sibike ngamaphethini okufuduka kwendawo nesikhathi sama-Hooded Cranes ebusika e-Izumi, eJapane, kanye nezindawo ezibalulekile zokuma ukuze zilondolozwe. Ama-crane amane amadala namahlanu ama-subadult, wonke asebusika e-Izumi, eJapane, afakelwe ama-satellite transmitter (uhlelo lwe-GPS-GSM) ezindaweni zawo zokuma enyakatho-mpumalanga yeShayina ngo-2014 nango-2015. Sihlaziye isikhathi nobude besikhathi sabantu abadala nama-subadult ekufudukeni kwentwasahlobo nasekwindla, kanye nesikhathi nobude besikhathi abahlala ngaso endaweni yokuzalela kanye neyokuhlala ebusika. Ngaphezu kwalokho, sihlaziye ukusetshenziswa komhlaba kwama-crane ezindaweni zokuma. Ama-crane amadala athatha isikhathi eside kakhulu ukufuduka kokubili enyakatho entwasahlobo (isilinganiso = izinsuku ezingu-44.3) kanye naseningizimu ekwindla (isilinganiso = izinsuku ezingu-54.0) uma kuqhathaniswa nama-crane ama-subadult (izinsuku ezingu-15.3 nezingu-5.2, ngokulandelana). Kodwa-ke, lezi zinyoni ezincane zazinesikhathi eside sasebusika (isilinganiso = izinsuku ezingu-149.8) kanye nezikhathi zokuzulazula (isikhathi sokuzalanisa kwabantu abadala) (isilinganiso = izinsuku ezingu-196.8) uma kuqhathaniswa nabantu abadala (izinsuku ezingu-133.8 kanye nezingu-122.3, ngokulandelana). Izindawo ezintathu ezibalulekile zokuma ziye zatholakala: isifunda esizungeze iMuraviovka Park eRussia, iSongnen Plain eShayina, kanye nogu olusentshonalanga yeNingizimu Korea, lapho ama-crane ayechitha khona isikhathi sawo esiningi sokufuduka (62.2 kanye no-85.7% entwasahlobo nasekwindla, ngokulandelana). Ngesikhathi sokufuduka, isikhathi sokuzulazula kanye nobusika, ama-Hooded Crane avame ukuhlala ezindaweni zokulima ukuze aphumule futhi ondle. Esikhathini esingesona sasebusika, ngaphansi kuka-6% wezindawo zokuma zazitholakala ezindaweni ezivikelwe. Sekukonke, imiphumela yethu inegalelo ekuqondeni amaphethini okufuduka kwendawo nesikhathi sama-Hooded Crane minyaka yonke emgwaqeni ondizayo osempumalanga, kanye nokuhlela izinyathelo zokulondolozwa kwalolu hlobo.
