Organism Niche Fast Facts:
Erect-Crested Penguins are an endemic speices to New Zealand and breed on the Bounty and Antipodes Islands and other surrounding biomes which include intertidal zones and oceanic zones.
Island biogeography shows that small breeding populations were sighted from Campbell Island to the Auckland Islands. In the 1940s, a pair was found on the Otago Peninsula of the New Zealand mainland. Some pairs have been found in the Falkland Islands and are occasional vagrants to Argentina, Antarctica, and Australia.
Erect-Crested Penguins live largely at sea during their pre-molt period which lasts from February to March and during the winter months of March to August.
They live in large colonies on rocky terrain, which is an essential part of their ecosystem for breeding.
In some locations, Erect-Crested Penguins breed in mono-specific colonies. In other areas, they live sympatrically with Southern Rockhopper penguins.
On the Bounty Islands, they breed in mixed colonies with albatross.
Population density is decreasing.
