Yellow-eyed penguins are one of the rarest of penguin species, and also one of the shyest. They are also monogamous, but only pair up when it’s time to breed. Yellow-eyed penguins nest in secluded parts of the forest, and the parents take turns bringing back fish for their chicks to eat. After six weeks, the chicks are grown enough to be left on their own and the family will part ways. This video depicts the patterns in behavior of parents and offspring that help offspring survive.
