Abstract:
Iyo Lesser White-fronted Goose (Anser erythropus), idiki pane "grey" geese, yakanyorwa seInogona Kuparara paIUCN Red List uye yakadzivirirwa munzvimbo dzese dzakasiyana. Kune vanhu vatatu, vane vashoma vakadzidza kuve vagari vekuMabvazuva, vakagovaniswa pakati peRussia neChina. Kunyanya kuremerwa kwekupfuya ma enclaves kunoita kuti zvisawanikwe nevaongorori. Sechinzvimbo chekushanya, kuronda shiri dziri kure kubva kunzvimbo dzechando kunobvumira kuongororwa kwemhando yadzo yezhizha. Kwenguva yemakore matatu, uye vachishandisa michina yekuronda GPS yakanyatsojeka, vanhu gumi nemumwe veA. erythropus vakateverwa kubva panzvimbo yakakosha yechando yekuChina, kusvika muzhizha, uye nzvimbo dzekutandarira kuchamhembe kwakadziva kumabvazuva kweRussia. Dhiyabhorosi yakawanikwa kubva pakutevera ikoko, yakatsigirwa nekuongorora kwepasi uye zvinyorwa zvinyorwa, zvakashandiswa kuenzanisa kugoverwa kwezhizha kweA. erythropus. Kunyange zvazvo mabhuku ekare achitsanangura mutsara wezhizha wezhizha, muenzaniso unoratidza kuti nzvimbo yekugara yezhizha inogoneka, kunyange zvazvo kuongorora kusvika nhasi hakugone kusimbisa A. erythropus iripo mukati memuenzaniso wemhando. Nzvimbo dzakanyanya kukodzera dzekugara dziri pamahombekombe eGungwa reLaptev, kunyanya iyo Lena Delta, muYana-Kolyma Lowland, uye madiki madiki eChukotka ane madiki madiki ekuwedzera kumusoro kwenzizi huru dzakadai seLena, Indigirka, uye Kolyma. Mukana wekuvapo kweA. erythropus une chekuita nenzvimbo dzine urefu husingasviki 500 m dzine mvura zhinji, kunyanya nzvimbo dziri pedyo nerwizi, uye mamiriro ekunze ane mvura yekunaya kwekota inodziya zvikuru inosvika 55 mm uye tembiricha inosvika 14°C muna Chikumi-Nyamavhuvhu. Kuvhiringidzika kwevanhu kunokanganisawo kukodzera kwesaiti, nekudzikira zvishoma nezvishoma muhupo hwezvipenyu kutanga kutenderera 160 km kubva kunogara vanhu. Kuteedzera kure kure kwemarudzi emhuka kunogona kuvharidzira gwanza reruzivo rinodiwa pakufungidzira kwakasimba kwemaitiro ekuparadzira marudzi munzvimbo dziri kure. Kuziva kurinani kwekugovewa kwezvipenyu kwakakosha mukunzwisisa mhedzisiro yakakura-yeecology yekukurumidza shanduko yepasirese uye kutanga nzira dzekuchengetedza kuchengetedza.
