Fiordland Penguin vs Erect-crested Penguin: common questions
How do their crests differ?
The Fiordland penguin has a bright yellow crest above each eye, while the erect-crested penguin has stiff, upright yellow crests standing straight up rather than the drooping style seen in relatives like the Fiordland penguin.
Which one breeds in rainforest and which on remote islands?
The Fiordland penguin breeds in dense temperate rainforest along New Zealand's southwestern coast, while the erect-crested penguin instead breeds on a small number of remote sub-Antarctic islands.
Which one has declined more severely?
The erect-crested penguin has declined far more severely, with a population collapse of over 70 percent in recent decades, compared with the Fiordland penguin's more gradual decline.
