Kakaruai / South Island robin
Petroica australis
At Risk - Declining
Curious, bold and often just a few steps away, the kakaruai or South Island robin, is one of Aotearoa’s most engaging forest birds. With their upright posture, intelligent eyes and habit of hopping close to people, kakaruai are a favourite among bushwalkers and bird lovers. But this charming curious behaviour means they are especially vulnerable to predators in many parts of their range.
Quick Facts:
- Kakaruai are known for their fearless curiosity – often following people through the forest, hoping they’ll disturb insects.
- They form strong pair bonds and stay in the same territory year-round. The female builds and incubates the nest, while her mate keeps her fed – visiting 2-3 times an hour to bring her food. Both parents then feed the chicks.
- Full song is a cheerful series of whistles with males taking it seriously: they sing from perches to defend territories and impress females, and bachelors spend much more time singing than paired males!
- They are clever foragers: trembling their feet and flicking their wings to flush out hidden insects on the forest floor.
- Key indicator species for healthy, pest-controlled forests – their presence means the bush is on the mend.
Helping kakaruai thrive means keeping forests safe from predators and rich in native understory – creating spaces where these inquisitive companions can sing, forage and raise their young.
