Āwhina te hangarau aroturuki i te tuhi i te hekenga tuatahi a te taiohi Whimbrel mai i Iceland ki Āwherika ki te Hauāuru

I roto i te mātauranga manu, he uaua tonu te rangahau mō te hekenga tawhiti o ngā manu taitamariki. Hei tauira, ko te Eurasian Whimbrel (Numenius phaeopus), hei tauira. Ahakoa kua aro turukihia e ngā kaipūtaiao ngā tauira hekenga ā-ao o ngā whimbrel pakeke, me te kohikohi i te nui o ngā raraunga, he tino onge ngā mōhiohio mō ngā whimbrel taitamariki.

Kua whakaatuhia e ngā rangahau o mua he rerekē ngā rautaki hekenga o ngā manu whimbrel pakeke i te wā whakaputa uri i te marama o Āperira me Mei i a rātou e haere ana mai i ō rātou whenua hotoke ki ō rātou wāhi whakaputa uri. Ko ētahi ka rere tika ki Iceland, ko ētahi ka wehea tā rātou haerenga kia rua ngā wāhanga me te tūnga. I muri mai, mai i te mutunga o Hūrae ki Ākuhata, ka rere tika te nuinga o ngā manu whimbrel pakeke ki ō rātou whenua hotoke i Āwherika ki te Hauāuru. Heoi, ko ngā mōhiohio nui mō ngā manu taitamariki—pērā i ō rātou ara hekenga me te wā—kua roa e noho ngaro ana, inā koa i te wā o tā rātou hekenga tuatahi.

I roto i tētahi rangahau tata nei, i whakamahia e tētahi tīma rangahau o Iceland ētahi taputapu aroturuki māmā e rua i whakawhanakehia e Global Messenger, arā, ko ngā tauira HQBG0804 (4.5g) me HQBG1206 (6g), hei aroturuki i ngā whimbrels taitamariki e 13. I whakaatuhia e ngā hua he rite me he rerekētanga whakamere i waenga i ngā whimbrels taitamariki me ngā whimbrels pakeke i te wā tuatahi o tā rātou hekenga ki Āwherika ki te Hauāuru.

Pērā i ngā pakeke, he maha ngā manu whimbrel taitamariki i rere tonu mai i Iceland ki Āwherika ki te Hauāuru. Heoi, i kitea anō hoki ngā rerekētanga motuhake. Ko ngā manu whimbrel taitamariki i te nuinga o te wā ka rere i muri i te wā i ngā pakeke, ā, he iti ake te tūponotanga ki te whai i te ara heke tika. Engari, he maha ake ā rātou tūnga i te ara, ā, he puhoi ake te rere. Nā ngā taputapu aroturuki a Global Messenger, i hopukina e te tīma o Iceland, mō te wā tuatahi, te haerenga heke tonu o ngā manu whimbrel taitamariki mai i Iceland ki Āwherika ki te Hauāuru, e whakarato ana i ngā raraunga tino nui hei mārama ki ngā whanonga hekenga a ngā manu whimbrel taitamariki.
