A Nat Geo Wild video shows an intense battle between two penguins. The cause? One found the other with his partner.
Penguins are known for fidelity to their mates. An average of 72 percent of penguins return to mate with the same bird as the previous year.
For some species, a short three-week mating period starts in late October. At this time, males and females hope to return to their nests together.
Sometimes this plan goes awry. “There are penguin breakups, but the reasons are often strictly logistical,” aviculturist Laura Dray explained to Nat Geo.
