Yini opholi abakhuluma ngayo: ucwaningo olusha olwenziwa izazi zezinyoni

Abacwaningi eNyuvesi yaseTexas baqhathanisa ukukhala kwamapholi amancane nokukhuluma kwezingane.

Kuvele ukuthi amatshwele athanda ukuxoxa wodwa uma amanye elele. Abanye baphinda amaphimbo ngemva kwabazali babo. Abanye benza eyabo imisindo yemvelo engafani nanoma yini enye.

Ama-parrots ngokuvamile aqala ukubhibhidla kusukela osukwini lwama-21 lokuphila.

Kodwa akugcini lapho. Ezinganeni ezingabantu, i-hormone yokucindezeleka ikhuthaza ukuthuthukiswa kwamakhono okuxhumana. Ukuhlola ukuthi ukucindezeleka kubathinta kanjani opholi, izazi zezinyoni zanikeza amatshwele i-corticosterone. Ilingana ne-cortisol yomuntu. Okulandelayo, abacwaningi baqhathanisa i-dynamics nontanga - amatshwele angazange anikezwe i-corticosterone.

Ngenxa yalokho, iqembu lamatshwele elinikezwa i-hormone yokucindezeleka laqala ukusebenza kakhulu. Amatshwele enza imisindo ehlukahlukene. Ngokusekelwe kulokhu kuhlolwa, izazi zezinyoni zaphetha ngokuthi:

I-hormone yokucindezeleka ithinta ukuthuthukiswa kwama-parrots ngendlela efanayo naleyo ethinta ngayo izingane.

Lesi akusona isifundo sokuqala esinjalo. Izazi zezinyoni zaseVenezuela zakha izidleke ezikhethekile ezenziwe ngamapayipi e-PVC esiteshini sezinto eziphilayo futhi zanamathisela amakhamera evidiyo amancane asakaza izithombe nomsindo. Lokhu kubuka kwamatshwele kwajoyinwa ososayensi baseNyuvesi yaseTexas. Bashicilele abakutholile kujenali yeRoyal Society of London Proceedings yeRoyal Society B. Lena i-analogue ye-Academy of Sciences e-UK.
