Abstract:

Bohai Black-tailed Godwit (Limosa limosa bohaii) imhando ichangowanikwa muEast Asian-Australasian Flyway. Zvichienderana nekutevera satellite kwevanhu makumi maviri nemumwe vaive vakamakwa kuchamhembe kweBohai Bay, China, kubva 2016 kusvika 2018, isu pano tinotsanangura kutenderera kwegore kweizvi subspecies. Shiri dzese dzaive neThailand senzvimbo yadzo yekumaodzanyemba 'yechando'. Kusimuka kwechirimo kwaive mukupera kwaKurume panguva yekutamira kuchamhembe, Bohai Bay ndiyo yaive yekutanga kumira nzvimbo kwavakapedza paavhareji mazuva makumi matatu nepfumbamwe (± SD = 6 d), ichiteverwa neInner Mongolia nedunhu reJilin (kumira kwe8 d ± 1 d). Kusvika kwenzvimbo dzekuberekesa muRussia Far East kwaive pakati pekupera kwaMay. Nzvimbo mbiri dzekuberekesa dzakaonekwa, neavhareji nzvimbo 1100 km dzakaparadzana; nzvimbo yokumabvazuva yakanga inopfuura kuparadzirwa kwaizivikanwa kwokubereka kweAsia kweBlack-tailed Godwit. Kutamira kuMaodzanyemba kwakatanga mukupera kwaChikumi, magodwits achitarisira kumira kwenguva refu panzvimbo mbiri dzakafanana dzekumisa dzinoshandiswa muchirimo, kureva Inner Mongolia neJilin dunhu (32 ± 5 d) neBohai Bay (44 ± 8 d), vamwe vanhu vachimira kwechitatu munzvimbo dzepakati-pasi dzeRwizi Yangtze ± 1 d ± 2 kumaodzanyemba). Pakupera kwaGunyana, vanhu vazhinji vaiteverwa vaive vasvika muThailand. Zvichienzaniswa nemhando dzemhando dzemhando, bohaii godwits dzine marongero akasiyana anoshamisa ekufamba uye moult, chidzidzo ichi chichiwedzera ruzivo rwekusiyana kwakasiyana-siyana kweblack-tailed godwits muEast Asia-Australian Flyway.
