Pfupiso:
Goose reLesser White-fronted Goose (Anser erythropus), diki pane "grey" geese, rakanyorwa serisingakwanise kubatwa paIUCN Red List uye rinodzivirirwa munzvimbo dzese dzerudzi. Kune marudzi matatu, ayo mashoma akadzidzwa ari eEastern, ari pakati peRussia neChina. Kure kure kwenzvimbo dzekuberekesa kunoita kuti dzisawanikwe nevaongorori. Sechinzvimbo chekushanyira, kutevera shiri dziri kure kubva kunzvimbo dzechando kunobvumira kuongorora nzvimbo dzadzo dzezhizha. Kwemakore matatu, uye vachishandisa michina yekutevera GPS yakarurama, gumi nerimwe reA. erythropus rakateverwa kubva kunzvimbo huru dzechando dzeChina, kusvika kunzvimbo dzezhizha, uye nzvimbo dzekugara kuchamhembe kwakadziva kumabvazuva kweRussia. Data rakawanikwa kubva pakutevedza ikoko, rakasimbiswa nekuongorora pasi uye zvinyorwa zvemabhuku, rakashandiswa kutevedzera kupararira kweA. erythropus muzhizha. Kunyangwe mabhuku ekutanga achitsanangura nzvimbo dzezhizha dzisina kurongeka, modhi iyi inoratidza kuti nzvimbo dzekugara dzezhizha dzakatevedzana dzinogoneka, kunyangwe kucherechedza kusvika pari zvino hakugone kusimbisa kuti A. erythropus iripo munzvimbo dzese dzerudzi. Nzvimbo dzakakodzera dziri pamhenderekedzo yeGungwa reLaptev, kunyanya Lena Delta, muYana-Kolyma Lowland, uye nzvimbo diki dzakadzika dzeChukotka dzine nzvimbo dzakamanikana dzemurwizi dziri kumusoro kwenzizi huru dzakadai seLena, Indigirka, neKolyma. Mikana yekuvapo kweA. erythropus ine chekuita nenzvimbo dzine urefu huri pasi pe500 m dzine nzvimbo dzakanyorova dzakawanda, kunyanya nzvimbo dzemurwizi, uye mamiriro ekunze ane mvura inonaya zvakanyanya inosvika 55 mm uye tembiricha iri pakati pe14°C muna Chikumi-Nyamavhuvhu. Kukanganiswa kwevanhu kunokanganisawo kukodzera kwenzvimbo, nekudzikira zvishoma nezvishoma kwekuvapo kwemarudzi kunotanga makiromita angangoita 160 kubva kunzvimbo dzinogara vanhu. Kutevera mhuka kure kunogona kuvhara musiyano weruzivo unodiwa kuti pave nekufungidzira kwakasimba kwemaitiro ekupararira kwemarudzi munzvimbo dziri kure. Ruzivo rwuri nani rwekupararira kwemarudzi rwakakosha mukunzwisisa mhedzisiro yakakura yekushanduka nekukurumidza kwenyika uye kugadzira nzira dzekuchengetedza kuchengetedza.
