The takahē is a large, flightless bird – the largest living rail bird in the world. Rails are a family of ground-living birds that live on every continent except Antarctica. Takahē are endemic to Aotearoa New Zealand, which means they naturally live here and nowhere else in the world. Takahē evolved without ground-dwelling predators. Like the kiwi, takahē adapted to this situation by developing a large body size, small wings and strong legs. On average, an adult takahē weighs 2–3.5 kg and stands about 500 mm high. This large body size is an advantage to species that live in cold environments.
