It reaches a length up to fourteen centimetres and therefore it is one of the largest white-eyes. The wingspan is 7.5 cm and the weight is about 30 grams. Its appearance is characterized by a pale green head, an olive green coloured neck and white throat and belly parts. A further feature is a conspicuous eye ring of white feathers. Males and females are coloured similarly. Its diet consists of fruits, berries, nectar, and insects. Its only habitat is a 5 km² large forested area around Mount Pitt on Norfolk Island where it lives solitary. In the breeding season from October to December the couple build a cup-shaped nest in which two white eggs are laid. The incubation time lasts eleven days and another eleven days later the juveniles became fully fledged.
The White-breasted Silver Eye is classified as Critically Endangered (CR), facing an extremely high risk of extinction in the wild.
