description Campbell Islands Teal Overview

The Campbell Islands teal (*Anas nesiotis*) is a small, flightless species of dabbling duck endemic to New Zealand's subantarctic Campbell Island group. It was presumed extinct until a small population was surprisingly rediscovered on the nearby Dent Island in 1975. The bird relies on running rather than flying to evade predators, an adaptation that left it highly vulnerable to introduced mammals. Conservation programs have since bred the species in captivity and reintroduced it to predator-free islands, making it a key focus for New Zealand wildlife preservationists.

help Campbell Islands Teal FAQ

How did the Campbell Islands teal avoid extinction?

The Campbell Islands teal was presumed extinct until a small population was surprisingly rediscovered on the nearby Dent Island in 1975. Because Dent Island had no introduced predators like rats, the flightless duck managed to survive there while dying out on the main Campbell Island.

What conservation efforts saved the Campbell Islands teal?

Conservationists captured individuals from the Dent Island population to establish a captive breeding program at the Pukaha Mount Bruce wildlife center. In 2004, after a massive, successful rat eradication campaign on Campbell Island, the New Zealand Department of Conservation reintroduced the teal back to its native habitat.

Why can't the Campbell Islands teal fly?

As an endemic species of New Zealand's subantarctic islands, the Campbell Islands teal evolved for thousands of years without mammalian land predators. This lack of predation led to evolutionary adaptations where the bird lost its ability to fly, relying instead on running and diving to forage for food.

What does the Campbell Islands teal eat?

As a species of dabbling duck, the Campbell Islands teal feeds primarily on small invertebrates and insects. They actively forage by sieving mud and shallow water through their bills along the island's tussock grasslands and shorelines.
