Oku kungenxa yokulahleka kwendawo yokuhlala kunye nokuloba ngokugqithisileyo kokutya kwabo okuphambili, iisardini (ipilchardi). Ii African penguin zasezikhuphisana ngeendawo zokuloba zorhwebo eKapa neesardines. Iindawo zokuloba zorhwebo zixabisa iibhiliyoni zeerandi kwaye ziqeshe abantu abaninzi. IiSardine yisource yokutya okuneprotein engaxabisi kakhulu kwaye ivunwa ngobuninzi kwinyanga ka March ukuya kuMeyi eMzantsi Afrika ekwalixesha lokukhwelana kwepenguin yaseAfrika. Ngexesha lokukhwelana zombini iintlobano zeAfrican penguin zenza izandi ezivakalayo ukubiza amaqabane azo.
