. It was quite small, brown and greyish; its head was brown apart from a pale grey eye-ring and a grey throat and chin, many parts of the animal varied to the colour of yellow, this being apparent in its bright yellow belly. A pregnant Lord Howe Gerygone would lay a clutch of three pink-tinged, brown-speckled eggs in a domed nest made up of dry bark, fibres, leaves, grass, moss and wool wrapped together with a spider web suspended from a twig. It was abundant in the forests of the island until the early 20th century. There have been no records of the species since 1928 and it is considered to be extinct
. Its extinction is almost certainly due to predation by Black Rat
