Penguins of several species form long-term pair bonds, often returning to the same partner across multiple breeding seasons. Pairs share incubation duties, with one parent fasting on the nest while the other forages at sea, sometimes for weeks at a time. The fasting partner can lose up to a third of its body weight before the other returns with food.

- B

- D
