<prompt> Fingqa isihloko: Kungase kube nzima ukungawunaki umsila wephawu, kodwa abantu abawazi umsindo owenziwe yimpaphe enhle yale nyoni. Ososayensi baye babonisa ukuthi ama - peacock anyakazisa imisila yawo ukuze enze umsindo ophansi kakhulu ukuba singawuzwa. Izinyoni ezingamaduna zingase zenze umsindo we-infrared ukuze zethuse isitha esiseduze noma ukuze zihehe isithandwa sazo. Ososayensi baye babonisa ukuthi ama - peacock anyakazisa imisila yawo lapho ebukisa isithombe esivamile ukuze enze umsindo ophansi kakhulu ukuba singawuzwa. Lolu cwaningo luthi izinyoni ezingamaduna zingase zenze umsindo we-infrared ukuze zisabe isitha esiseduze noma ukuze zihehehe inkosikazi enqamula endaweni enothuli. Abacwaningi base-University of Manitoba eWinnipeg, eCanada, baye babonisa ukuthi lezi zinyoni zikhipha imisindo engaphansi kwe-infrasound - engaphansi kuka-20 hertz - zisebenzisa imisila yazo nokuthi amanye ama-peacock ayasabela kuyo. Abantu abaningi bezwa imisindo ephakathi kuka-20 no-20 000 hertz. UDkt. James Hare waphawula ukuthi iphawundi libonisa futhi linyakazisa umsila walo odongeni endaweni yokugcina izilwane, okuyinto ayibona ibukeka njengesitsha sesathelayithi futhi yamenza wazibuza ukuthi ingabe le nyoni iyazilalela yini, kubika i - BBC Earth. Lokhu kwabangela ukuba kwenziwe ucwaningo, okwamholela yena nomfundi ophumelele esikoleni u-Angela Freeman ukuba baqophe umsindo wama-pawn angu-46 azinyakazisa izimpaphe zawo lapho edlala. Ama-pawn abesilisa nabesifazane baqala ukuqapha futhi bazulazula lapho abacwaningi bedlala imisindo ephansi kubo, abesilisa isithombe sesitoko bekhala. UCharles Darwin wasikisela okokuqala ukuthi isitimela sika-phawn sikhonza ukuheha abesifazane futhi izifundo ziye zabonisa ukuthi abesifazane bavame ukukhetha abesilisa abanezici zesilisa ezidlulele kakhulu. U-Amoz Zahavi wathi isitimela sibonisa ukufaneleka kwendoda. Amaduna anezitimela ezihlaba umxhwele aye abonakala enempilo kakhudlwana, okusikisela ukuthi umhlobiso ubonisa ikhono lendoda lokusinda. Umgomo wakhe wokukhubazeka uthi njengoba abesilisa abanemibala egqamile noma izimpaphe ezinkulu ngokukhethekile beyokhanga izilwane ezidla ezinye, kumelwe babe abafaneleka ngokwengeziwe ukuze basinde. Kucatshangwa ukuthi izinsikazi zikhetha abangane abanezakhi zofuzo ezinhle, ngakho abesilisa abanezici zobulili ezidlulele, njengezitimela ezinkulu, bavame ukuba...  <response>: Abacwaningi base - University of Manitoba, eCanada, baye babonisa ukuthi ama - peacock enza imisindo ye - infrasound - engaphansi kuka - 20 hertz - esebenzisa imisila yawo. Izinsikazi zaziphapheme kakhudlwana lapho zizwa umsindo futhi abesilisa bememeza. Ama-peacock angamadoda angase asebenzise i-infrasound ukuze agcine indawo yawo. Zingase futhi zisebenzise umsindo ukuze zihehe umlingani ehlathini elinamahlathi.
