A crested penguin that has laid two eggs will take a good look at them and boot the smaller one out of the nest, the better to focus her attentions on the presumably heartier chick in the bigger shell.
Ćubasti pingvin koji je izlegao dva jaja  dobro će ih pogledati i manje će izbaciti iz gnijezda, da se može bolje fokusirati  na vjerojatno zdravije mladunče u većoj ljusci.
