Abstract:

Makumi maviri ekuFar East Greylag Geese, Anser anser rubrirostris, akabatwa uye akaiswa matanda eGlobal Positioning System/Global System yeMobile Communications (GPS/GSM) kuti aone nzvimbo dzekuberekera nedzemuchando, nzira dzekutama uye nzvimbo dzekumira. Telemetry data kekutanga yakaratidza kubatana pakati penzvimbo dzechando dzeRwizi rweYangtze, nzvimbo dzekumira kuchamhembe kwakadziva kumabvazuva kweChina, uye nzvimbo dzekuberekera/kunyungudutsa kumabvazuva kweMongolia nekuchamhembe kwakadziva kumabvazuva kweChina. 10 ye20 vanhu vakamaka vakapa data yakakwana. Vakamira pakutama paYellow River Estuary, Beidagang Reservoir neXar Moron River, vachisimbisa nzvimbo idzi senzvimbo dzakakosha dzekumisa vanhu ava. Nguva yepakati yekutama kwechirimo yaive mazuva 33.7 (vanhu vakatanga kutama pakati pa25 Kukadzi na16 Kurume uye vakapedza kutama kubva 1 kusvika 9 Kubvumbi) zvichienzaniswa nemazuva 52.7 mumatsutso (26 Gunyana-13 Gumiguru kusvika 4 Mbudzi-11 Zvita). Nguva yekumira yepakati yaive 31.1 uye 51.3 mazuva uye nhanho yepakati yekufamba yaive 62.6 uye 47.9 km/zuva pakutama kwechirimo nematsutso, zvichiteerana. Misiyano yakakosha pakati pekufamba kwechirimo nekumatsutso panguva yekufamba, nguva yekumira uye kumhanya kwekufamba kwakasimbisa kuti tagged mukuru Greylag Geese akafamba nekukurumidza muchirimo kupfuura matsutso, achitsigira fungidziro yekuti vanofanirwa kuve nenguva-inogumira panguva yekutama kwechirimo.
