Chidule:

Chidule: Mbalame ya Oriental Stork (Ciconia boyciana) yalembedwa ngati 'Yomwe Ili Pangozi' pa International Union for the Conservation of Nature (IUCN) Red List of Threatened Species ndipo yaikidwa m'gulu loyamba la mitundu ya mbalame zotetezedwa mdziko lonse ku China. Kumvetsetsa mayendedwe a nyengo ndi kusamuka kwa mtundu uwu kungathandize kusungira bwino kuti anthu ambiri azitha kukhalamo. Tinalemba ana 27 a m'nyanja ya Xingkai ku Sanjiang Plain ku Heilongjiang Province, China, tinagwiritsa ntchito GPS tracking kuti tiwatsatire kuyambira 2014-2017 ndi 2019-2022, ndipo tinatsimikizira njira zawo zosamukira mwatsatanetsatane pogwiritsa ntchito ntchito yowunikira malo ya ArcGIS 10.7. Tinapeza njira zinayi zosamukira nthawi ya autumn: njira imodzi yodziwika bwino yosamuka mtunda wautali momwe adokowe ankasamukira m'mphepete mwa nyanja ya Bohai Bay kupita pakati ndi pansi pa Mtsinje wa Yangtze kuti akakhale m'nyengo yozizira, njira imodzi yosamuka mtunda wautali momwe adokowe ankakhalira m'nyengo yozizira ku Bohai Bay ndi njira zina ziwiri zosamuka momwe adokowe ankadutsa Bohai Strait mozungulira Mtsinje wa Yellow ndikukhala m'nyengo yozizira ku South Korea. Panalibe kusiyana kwakukulu pa chiwerengero cha masiku osamuka, masiku okhala, mtunda wosamuka, chiwerengero cha masiku oima komanso chiwerengero cha masiku omwe amakhala pamalo oima pakati pa kusamuka kwa autumn ndi masika (P > 0.05). Komabe, adokowe ankasamukira mofulumira kwambiri masika kuposa nthawi ya autumn (P = 0.03). Anthu omwewo sanawonetse kubwerezabwereza kwakukulu mu nthawi yawo yosamuka komanso kusankha njira nthawi ya autumn kapena masika. Ngakhale adokowe ochokera pachisa chimodzi adawonetsa kusiyana kwakukulu pakati pa njira zawo zosamuka. Malo ena ofunikira oimikapo nyama adapezeka, makamaka m'chigawo cha Bohai Rim ndi ku Songnen Plain, ndipo tidapitiliza kufufuza momwe nyamazi zilili panopa m'malo awiri ofunikirawa. Ponseponse, zotsatira zathu zimathandiza kumvetsetsa kusamuka kwa pachaka, kufalikira ndi momwe nyamazi zikutetezera mbalame za ku Oriental Stork zomwe zili pangozi ndipo zimapereka maziko asayansi pazisankho zosungira nyamazi komanso kupanga mapulani a zochita za nyamazi.
