The riroriro or grey warbler (Gerygone igata) often sneaks under the radar unless your ear is attuned to the male’s call, or you recognise it little upturned bill.
But this is one of the commonest endemic birds, regularly observed across the inner west of Tāmaki Makaurau. You’ll find them in gardens, parks and reserves, often flitting around the tips of branches feeding (exclusively) on insects. As ever, we encourage you to record sightings on eBird.
