Izinyoni zingakwazi ukufunda ukuthi yikuphi ukudla okufanele zikudle nokuthi yini okufanele zikugweme ngokubuka ezinye izinyoni zenza into efanayo kumabonakude, ngokusho kocwaningo olusha lweNyuvesi yaseCambridge. Lokhu kuvumela ama-chickadees ukuthi akhethe kangcono ama-alimondi amahle nanambitheka kabi.
, eshicilelwe muva nje kuyi-Journal of Animal Ecology, ibonise ukuthi amabele aluhlaza (Cyanistes caeruleus) kanye nama- great tits (Parus major) afunda lokho okungafanele akudle ngokubuka amavidiyo amanye amabele ekhetha ukudla ngokuzama nangephutha. Lokhu okuhlangenwe nakho kokubhalelana kungabasiza ukuba bagweme ubuthi obungaba khona ngisho nokufa.
Abacwaningi basebenzisa ama-almond flakes avaliwe ngaphakathi kwephakheji lephepha elimhlophe. Ama-alimondi ahlukahlukene aphehliwe ayecwiliswa ekhambi elibabayo. Ukusabela kwezinyoni lapho zikhetha amaphakethe e-alimondi amahle nanambitheka kabi kwaqoshwa futhi kwaboniswa ezinye izinyoni. Izikhwama ezimbi zokunambitha zazinophawu oluyisikwele oluphrintiwe kuzo.
Inyoni yabuka njengoba ezinye izinyoni zayo zithola ukuthi yimaphi amaphakethe e-alimondi anambitheka kakhulu. Ukusabela kwenyoni yeTV ekudleni okungajabulisi kwakusukela ekunikine ikhanda kuya ekwesuleni uqhwaku lwayo ngamandla. Kokubili osisi abaluhlaza kanye nosisi abakhulu badle amaphakethe ambalwa ezikwele ngemva kokubuka ukuziphatha kwezinyoni okurekhodwe ku-TV.
βAmabele aluhlaza okwesibhakabhaka namabele amakhulu adla ndawonye futhi anokudla okufanayo, kodwa angase ahluke ekungabazeni kwawo ukuzama ukudla okusha,β kusho uLiisa Hamalainen, umcwaningi eMnyangweni Wezoology eNyuvesi yaseCambridge. "Ngokubuka abanye, bangafunda ngokushesha nangokuphephile ukuthi iyiphi inyamazane okufanele bayiqondise." Lokhu kunganciphisa isikhathi namandla abawachitha bezama ukudla okuhlukahlukene futhi kubasize bagweme imiphumela eyingozi yokudla ukudla okunobuthi.β
Lolu wucwaningo lokuqala olukhombisa ukuthi osisi abaluhlaza bayakwazi ukufunda njengamabele amakhulu ngokubheka imikhuba yokudla yezinye izinyoni.
