Fiordland crested penguins breed in underground burrows and caves, with incubation periods of 35-37 days and fledging occurring 3-4 months after hatching.

Rockhopper penguins exhibit a unique breeding strategy where males arrive at colonies 10-14 days before females to establish and defend nesting territories during their September breeding season.
