Iintaka zinokufunda ukuba kukuphi ukutya okufuneka sikutye kunye nokuba yintoni onokuyiphepha ngokubukela ezinye iintaka zenza into efanayo kumabonwakude, ngokutsho kophando olutsha oluvela kwiYunivesithi yaseCambridge. Oku kuvumela ii-chickadees ukuba zikhethe ngcono iialmondi ezilungileyo nezimbi.
, epapashwe kutshanje kwi-Journal ye-Animal Ecology, ibonise ukuba i-blue tits (i-Cyanistes caeruleus) kunye ne-big tits (i-Parus enkulu) yafunda into engafanele ityiwe ngokubukela iividiyo zamanye amabele ngokukhetha ukutya ngokuzama kunye nephutha. La mava embalelwano anokubanceda baphephe ityhefu enokubakho kwanokufa.
Abaphandi basebenzisa ii-almond flakes ezitywinwe ngaphakathi kwepakethe yephepha elimhlophe. Iialmondi ezahlukahlukeneyo ezigwetyiweyo zazigalelwe kwisinyibiliko esinencasa ekrakra. Indlela ezisabela ngayo ezi ntaka xa zikhetha iipakethe zom-amangile ezintle nezinencasa ezimbi zarekhodwa zaza zaboniswa ezinye iintaka. Iingxowa ezimbi zokungcamla zazinophawu olusisikwere olushicilelwe kuzo.
Le ntaka yabukela njengoko ezinye iintaka zayo zifumanisa ukuba zeziphi iipakethi zom-amangile zinencasa kakhulu. Indlela eyasabela ngayo le ntaka kamabonwakude ngokutya okungathandekiyo yayisusela ekunikineni intloko ukusa ekusuleni umlomo wayo ngamandla. Omabini amabele aluhlaza kunye namabele amakhulu atya iipakethi ezimbalwa ezikrakra zesikwere emva kokubukela ukuziphatha kweentaka ezirekhodwe kumabonakude.
"Ii-blue tits kunye ne-tits ezinkulu zitya kunye kunye nokutya okufanayo, kodwa zinokwahluka ekuthandeni kwabo ukuzama ukutya okutsha," kusho uLiisa Hamalainen, umphandi kwiSebe leZoology kwiYunivesithi yaseCambridge. Ngokujonga abanye, banokufunda ngokukhawuleza nangokukhuselekileyo ukuba leliphi ixhoba elilungele ukujolisa. Oku kunokunciphisa ixesha namandla abawachitha bezama ukutya ezahlukahlukeneyo yaye kwakhona kubanceda baphephe imiphumo eyingozi yokutya ukutya okunetyhefu.β
Olu luphononongo lokuqala olubonisa ukuba i-blue tits ikwazi ukufunda njengamabele amakhulu ngokujonga imikhwa yokutyisa yezinye iintaka.
