Penguins in Bounty Islands
Bounty Islands are linked here mainly with Erect-crested Penguin. Regional hubs with one species are still useful: they show the place-specific trap that bird is in.
Bounty Islands are part of the penguin world because the surrounding seas, nesting ground, and climate make life possible there. On this page that means one bird first: Erect-crested Penguin. With an extremely restricted breeding range and low reproductive flexibility, this species has very little buffer when conditions turn poor.
