This is endemic to New Zealand, being found throughout the country including several offshore islands.
These tiny birds are 10-11 cm long and weigh 6-7 g.
The grey gerygone is mostly found in temperate forests, but also in scrublands, mangroves, arable land and urban areas.
They feed on spiders, insects and their larvae.
Grey gerygones breed in August-January. The nest is built by the female, using material collected by the male, consisting of a pear-shaped structure with a side entrance made of grass, leaves, rootlets and moss, held together with spider webs. The nest is lined with feather and other soft material and attached to a twig up to 7 m above the ground. The female lays 3-6 pinkish-white eggs with reddish-brown speckles, which she incubates alone for about 19 day. The chicks are fed by both parents and fledge 15-19 days after hatching. Each pair usually raises 2 broods per season.
IUCN status – LC (Least Concern)
This species has a large breeding range and is described as generally common. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
