Yellow-eyed Penguin vs Erect-crested Penguin: common questions
Which one has suffered a more dramatic population collapse?
The erect-crested penguin has suffered the more dramatic collapse, with populations falling by more than 70 percent in recent decades for reasons that remain only partly understood.
Which one nests completely alone?
The yellow-eyed penguin is the solitary nester, hiding its nest alone within coastal forest, while the erect-crested penguin breeds on remote islands without the same documented solitary habit.
Which one is harder for researchers to study?
The erect-crested penguin is considered one of the least studied penguin species, due to the remoteness of its breeding islands, while the yellow-eyed penguin is comparatively well documented and closely monitored.
