Cover Story: Moas were extinct birds once lived in New Zealand, with some giants reaching 275 kg. Some moa species had extreme reversed sexual size dimorphism (RSSD), i.e., females were much larger than males. We find RSSD significantly increased the safety margin of contact incubation by the lighter males. Two different strategies were adopted by giant birds—one is RSSD and thinner shells, represented by some moa species; the other is no RSSD and regular shells, represented by ostriches and giant elephant birds.
