A small, noisy songbird endemic to New Zealand, found on the South and Stewart Islands. Favors myriad forest types. Note brown upperparts with an ashy-gray face and neck, and pale creamy-brown underparts. Often located first by its harsh chattering contact calls and canary-like song. Forms fast-moving flocks in the canopy that will come down to investigate “squeaking.” Associates with other species such as Silvereye and Gray Gerygone in the non-breeding season, forming noisy, continuously chattering flocks. Pipipi is the main host of the parasitic Long-tailed Koel, and so adults can be encountered feeding a much larger Koel chick. Distinguished from Dunnock by lighter underparts; does not feed on the ground. Look for sharp contrast between gray face and lighter underparts and larger size to distinguish from Gray Gerygone.
