Their Story
Pīpipi/ brown creepers are exceptionally charming, chatty birds. They’re often difficult to spot as their plumage enables them to blend in excellently among the branches. Their constant and distinctive chatter often gives them away. They, along with their sister species, mohua and pōpokatea, are known for forming large flocks. In winter, these flocks can consist of many unrelated species including: tīeke, kākāriki and pīwakawaka. Brown creepers were once abundant across Te Wai Pounamu and Rakiura, but are now only common in high altitude forest or areas with low pest abundance. They are unfortunately not established within the Sanctuary despite there being a nearby population.
Conservation Status

Not Threatened
Populations are stable across the South and Stewart Islands.
Population

Widespread and locally common throughout South Island and Stewart Island forests. Occasionally recorded within the Brook Waimārama Sanctuary.
Voice

Constant, lively chatter interspersed with a rapid, tumbling song — often described as “whistling while doing cartwheels.”
Food

Feeds mainly on invertebrates and occasionally fruit, foraging from low branches to the upper canopy.
Subtle in colour though charming up close, pīpipi display a blend of brown and light-buff plumage with a grey face. Males, females, and juveniles look similar. They are small and subtle coloured birds, but they make their presence known with their loud and constant chattering calls in their small flocks.
Active and sociable, pīpipi often forage in small flocks, especially outside the breeding season. They feed mainly on invertebrates such as caterpillars, beetles, spiders, and occasionally fruit. Foraging occurs from a few metres above the ground up to the canopy, but rarely on the forest floor. Their quick, tumbling whistles have been described as “like someone whistling while doing cartwheels.”
Breeding takes place from September to February. Pīpipi are monogamous, usually pairing for life. Females build deep, cup-shaped nests high in the canopy and lay 2–4 eggs. The female incubates and broods, while both parents feed the chicks once hatched. Fledglings leave the nest after 18–22 days and become independent within 35–65 days. Males may continue feeding fledglings as females begin new nests, and pairs may attempt up to four clutches per season — though two broods are typical. Remarkably, during drought years, unsuccessful pairs have been seen helping feed neighbouring young, showing rare cooperative behaviour.
Pīpipi inhabit native and exotic forests and shrublands throughout Te Waipounamu and Rakiura. Historically widespread across the South Island, they remain common in western and southern forests. Occasional sightings in the Brook Waimārama Sanctuary suggest the recovering ngahere may once again support this energetic species.
Once abundant across Aotearoa’s southern forests, pīpipi populations declined with large-scale forest clearance during the 19th century. Many intact lowland forests have more recently lost their creeper populations due to predation, usually from rats. Today, they are classed as Not Threatened and appear stable, though climate change may allow rats to invade their higher altitude refugia. This species, like most endemic forest birds, responds well to pest removal.
Although not yet resident, pīpipi have been occasionally sighted within the Sanctuary’s upper forest. Their absence remains a small mystery, perhaps having missed the boat like the yellow-crowned kākāriki, which were not long ago heard in the Brook catchment, but have since become exceedingly rare in the Richmond Ranges. Pest control within the Sanctuary halo would facilitate the reestablishment of this species. Perhaps their establishment is made difficult by the abundance of territorial birds like kakaruai/ South Island robins since the removal of mammalian pests.
Pīpipi often form mixed flocks with kākāriki, fantails, grey warblers, and mōhua as an adaptive strategy that may help spot predators or disturb insect food more effectively.
