About Gerygone igata (Quoy & Gaimard, 1830)
The grey warbler (Gerygone igata) has a long tail that is darker than its grey-brown body, with white markings on the tail tip and a white underside to the tail. There is minimal sexual dimorphism between males and females; the only consistent difference is that females are usually smaller than males. This is an especially small bird, weighing approximately 6.5 grams with an average length of only around 10 centimeters. Adult grey warblers have a characteristic ruby-red eye, while juveniles have brown eyes, plus yellowish feathers on the face and underbody. The species' nest is particularly unique among birds: it is a pear-shaped, dome-shaped hanging nest with a circular entrance hole on its side. Grey warblers are common across all of New Zealand's main islands and many offshore islands, but they do not occur in open country or alpine areas. They are well-established in both native and exotic forests, and can be found almost anywhere that has some tree or shrub cover.
