Whakarāpopototanga:

E rua tekau ngā Kākāriki o te Rawhiti ki te Tonga, arā, ko Anser anser rubrirostris, i hopukina, ā, i whakauruhia ki ngā taputapu tirotiro Pūnaha Tūnga Ao/Pūnaha Whakawhitiwhiti Waea Pūkoro (GPS/GSM) hei tautuhi i ngā wāhi whakaputa uri me ngā wāhi hotoke, ngā ara hekenga me ngā wāhi taunga. Mō te wā tuatahi, i whakaatuhia e ngā raraunga telemetry ngā hononga i waenga i ō rātou wāhi hotoke o te Awa Yangtze, ngā wāhi taunga i te raki-mā-rāwhiti o Haina, me ngā wāhi whakaputa uri/whakaheke uri i te rawhiti o Mongolia me te raki-mā-rāwhiti o Haina. Tekau o ngā kākāriki 20 i tohua i whakarato i ngā raraunga e ranea ana. I tū rātou i te hekenga ki te awaawa o te Awa Kōwhai, te Puna Wai o Beidagang me te Awa o Xar Moron, e whakaū ana i ēnei wāhi hei wāhi taunga nui mō tēnei taupori. Ko te roanga o te hekenga o te puna he 33.7 ngā rā (i tīmata ngā kākāriki ki te heke i waenga i te 25 o Pēpuere me te 16 o Poutū-te-rangi, ā, i oti te hekenga mai i te 1 ki te 9 o Paenga-whāwhā) ki te whakarite ki te 52.7 ngā rā i te ngahuru (26 o Hepetema–13 o Oketopa tae noa ki te 4 o Noema–11 o Tīhema). Ko te roanga o te taunga waenga he 31.1 me te 51.3 rā, ā, ko te tere haere waenga he 62.6 me te 47.9 km/rā mō te hekenga o te kōanga me te ngahuru. Nā ngā rerekētanga nui i waenga i te hekenga o te kōanga me te ngahuru i runga i te roanga o te hekenga, te roanga o te taunga me te tere hekenga i whakaū i tere ake te haere o ngā Kākāriki pakeke kua tohua i te kōanga i te ngahuru, e tautoko ana i te whakapae me nui ake te wā e herea ana e rātou i te hekenga o te kōanga.
