Ibisobanuro:

Abagera kuri 20 bo mu burasirazuba bwa Greylag Geese, Anser anser rubrirostris, barafashwe bashyirwaho ibikoresho bya Global Positioning System / Global System for Mobile Communication (GPS / GSM) kugira ngo bamenye aho ubworozi n’imbeho, inzira z’abimukira n’ahantu hahagarara. Amakuru ya telemetrie ku nshuro ya mbere yerekanaga isano iri hagati y’imvura y’imvura ya Yangtze, aho bahagarara mu majyaruguru y’Ubushinwa, hamwe n’ubworozi / gushonga mu burasirazuba bwa Mongoliya no mu majyaruguru y’Ubushinwa. 10 kuri 20 bashizweho abantu batanze amakuru ahagije. Bahagaritse kwimuka ku ruzi rw’umuhondo, ikigega cya Beidagang n’umugezi wa Xar Moron, bemeza ko utu turere ari ahantu nyaburanga bahagarara kuri aba baturage. Igihe cyo kwimuka hagati yimvura cyari iminsi 33.7 (abantu batangiye kwimuka hagati ya 25 Gashyantare na 16 Werurwe barangiza kwimuka kuva 1 kugeza 9 Mata) ugereranije niminsi 52.7 mumuhindo (26 Nzeri - 13 Ukwakira kugeza 4 Ugushyingo - 11 Ukuboza). Igihe cyo guhagarara giciriritse cyari iminsi 31.1 na 51.3 naho umuvuduko wo hagati wurugendo wari 62,6 na 47.9 km / kumunsi kwimuka nimpeshyi. Itandukaniro rinini hagati yimuka nimpeshyi igihe cyo kwimuka, igihe cyo guhagarara hamwe n’umuvuduko wimuka byemeje ko abantu bakuze Greylag Geese bakoze urugendo rwihuta mu mpeshyi kuruta igihe cyizuba, bishyigikira hypothesis ko bagomba kuba igihe - gito mugihe cyo kwimuka kwimuka.
