Do Penguins Mate for Life?

Answer:

Penguins are mostly monogamous, however there are some species like the Emperor Penguin which is serially monogamous, the mate with one couple for the whole season but the next year they will probably mate with another penguin as the urgent need for breeding will make them avoid waiting for the same couple the following year.

African and Magellanic, Gentoo and Royal penguins are examples of monogamous penguin species. A very interesting fact in the mating of the penguins is that both, male and female, are involved in the preparation of the nest and the care of the chicks, behavior that is not seen in many species of animals.
