The rockwarbler (Origma solitaria), is a bird in the family Acanthizidae. It is the only bird species endemic to the mainland of the state of New South Wales in Australia. The rockwarbler was described and illustrated in 1808 by the English artist and naturalist John Lewin under the binomial name Sylvia solitaria. For many years it was the only member of the genus Origma until genetic work showed that it was related to two species of mousewarblers from New Guinea. The rockwarbler diverged from the common ancestor of the other two species around 9 million years ago. Rockwarbler has been designated the official name by the International Ornithologists' Union (IOC). Common names also include cataract-bird, cave-bird, origma, rock-robin, and sandstone robin. A former common name, hanging dick, came about from its nest, which hangs suspended in a cave. It has no subspecies.
The rockwarbler is 14 cm (5.5 in) in length and weighs around 14 g (0.5 oz), with predominantly dark grey-brown plumage, darker wings and more red-brown underparts, cinnamon-tinged face and forehead, and whitish throat. Its tail is black. Adult males and females have similar... Wikipedia →

With luck
About 10% of wildlife watchers report a Rockwarbler sighting in Blue Mountains National Park on a given day, based on 463 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th most-seen of the 196 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March–August and October
In those months about 10% of wildlife watchers report a Rockwarbler in Blue Mountains National Park on a given day, against under 5% in September and November–February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Rockwarbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Rockwarbler sightings, Blue Mountains National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Royal National Park (Australia, about 10%).
Same family: Acanthizidae
The closest relatives of the Rockwarbler that you can see in Blue Mountains National Park (family Acanthizidae, Thornbills and Allies) are Brown Thornbill (about 60%), White-browed Scrubwren (about 40%) and Striated Thornbill (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rockwarbler is recorded against all the birds logged in Blue Mountains National Park (463 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
