The rockwarbler (Origma solitaria) is a species of bird in the Australian warbler family Acanthizidae. It is found only in the Australian state of New South Wales, where its preferred habitat is woodland with cliffs and gullies and exposed sandstone or limestone rocks. Its nest is a hanging structure in a cave, made of grasses, roots, bark and moss, with spider web used as an adhesive. The species is listed as being of least concern by the International Union for Conservation of Nature. This rockwarbler was photographed in the Royal National Park.Photograph credit: John Harrison
