New Zealand kea maparrots ane pfungwa yekuseka!
Boka revasayendisiti vanobva kuNew Zealand neAustralia vakaratidza kuti kea maparrots anoshandisa imwe trill, inofananidzwa nekuseka kwevanhu. Pashure pekuongorora kwakatevedzana, nyanzvi dzeshiri dzakaona kuti kutamba marekodhi e“kuseka kweshiri” kunokanganisa maitiro emaparrot ekuNew Zealand.
Zvinoenderana nechinyorwa chiri muCurrent Biology, kuedza kwakaitwa nevanyori pamapoka emusango kea kwakabatsira kusvika pamhedziso iyi. Masayendisiti akarekodha marudzi akati wandei emanzwi akaitwa nemaparrots panguva dzakasiyana. Kurekodha trill panguva yemitambo inoshanda yakakanganisa boka rekea nenzira inowirirana: shiri dzakatanga kudheerera uye kurwisana nenzira yekutamba, pasina kuratidza utsinye chaihwo.
Kufanana nekuseka kwevanhu, iyo trill yemitambo yema nestors inotapukira uye inokanganisa zvakanyanya mamiriro epakeji maitiro.
Mhando 5 dzeruzha dzakaridzwa kumaparrots, asi shiri dzakangopindura "kuseka" nemitambo. Sezvineiwo, iyo kea isina kuita pakutanga haina kubatanidza kune yagara ichitamba kea, asi yakatanga kupusa neshiri dzisingabatanidzi mukunakidzwa, kana kushandisa zvinhu zveizvi, kana kutanga kuita acrobatic stunts mumhepo. Rumwe ruzha rwakamutsa kutamba pakati pevaridzi, asi harina kushanda sekukoka kumutambo, asi kungoratidzwa semanzwiro mushiri imwe neimwe.
Kurekodha kwakapesvedzera chimiro chemanzwiro, asi kwete chimiro, nekuti chakasimba uye chakagadzikana.
Mushure mekutamba trill kwemaminetsi mashanu, kea akatanga kupusa ndokuenderera mberi kwemamwe maminetsi mashanu asina kunzwa trill. Pakazara, kuedza kwakatora maminetsi gumi nemashanu: 5 maminetsi kusati kwatanga "kuseka" (apo shiri dzakasiiwa dzega), 5 maminetsi eruzha (kea akatanga kupusa) uye 15 maminetsi mushure mekuyedza, apo. mhata dzakadzikama.
Muchisikigo, kutamba kworudo pakati peshiri nemhuka dzine mitezo yakasiyana kunoratidza kutanga kwekupfimbana uye kutanga kwemwaka wokuberekesa. Panyaya yemaparrots ekuNew Zealand, zvinhu zvakati siyanei. Mushure mekunzwa kurekodha kwe "kuseka", vese varume nevakadzi vemazera akasiyana vakaratidza chiitiko mumitambo yemakomiki.
Kuseka kweNew Zealand maparrots kunozivikanwa seanofananidzwa nekuseka kwevanhu uye mamwe marudzi. Semuenzaniso, makonzo anewo inzwi rinogona kunzi kuseka. Asi kuyedza kusimbisa fungidziro iyi yaive isina hunhu pane yekea. Makonzo akatangawo kutamba achipusa paakanzwa “kuseka”.
Panguva yekuedza, mhuka dzakapofumadzwa kana kuti matsi. Makonzo matsi haana kuita nezwi rakadzokororwa uye haana kuratidza kutamba, asi maitiro emakonzo mapofu akachinja zvakanyanya: vakatanga kutamba uye vakatanga kuratidza kufara kuhama dzavo.
Kukwanisa kweparrots kutevedzera kuseka kwevanhu hakufaniri kuvhiringidzwa ne trill ye "kuseka". Maparrots ishiri dzinobudirira kutevedzera marudzi ose ekurira, asi kuikopa hakutakuri chikamu chepfungwa, apo trill iri kuratidzwa kwemanzwiro eshiri pachayo.
