Grey Gerygone

Gerygone igata

Also known as Grey Warbler, Riroriro, Rainbird, New Zealand Gerygone

Grey gerygones are tiny, energetic forest songbirds that construct elaborate, enclosed pear-shaped nests with a side entrance tunnel suspended from tree forks. They often reveal their presence with an intricate, wavering trill that carries clearly through native bush and suburban gardens. In spring, their nesting cycle is closely tied to the shining bronze-cuckoo, which relies on them as its primary brood host across New Zealand.

Responsible observation
  • Listening: Follow the delicate, wavering trill up into the dense shrub canopy where birds flutter.
  • Hovering: Look for rapid hovering maneuvers as they snatch small caterpillars off leaf undersides.
  • Nesting Season: Keep distance from hanging pear-shaped moss nests woven in slender tree forks.
