The ashy tailorbird (Orthotomus ruficeps) is a species of songbird from Southeast Asia, formerly placed in the "Old World warbler" assemblage, it but now placed in the family Cisticolidae. The ashy tailorbird was described by the French ornithologist René Lesson in 1830. It was once treated as being conspecific (the same species) as the olive-backed tailorbird, but the two species are genetically distinct and act as such where their range overlaps in Java. Nine subspecies have been described.
The species is found across Southeast Asia, ranging from southern Myanmar and southern Thailand through the Malay Peninsula and Singapore. It is found widely across Greater Sunda Islands, namely Borneo, Sumatra and Java, as well as smaller islands near these, including the Philippine island of Mapun (which is close to Borneo). Another disjunct population is found in southern Vietnam and Cambodia.
Its natural habitats is typically lowland forests close to the coast, but it has been recorded up to 900 m (3,000 ft) on Sumatra and Borneo. It can occupy a range of forested habitats including mangrove forest, secondary forest, swamp forest and scrubland... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Ashy Tailorbird is recorded against all the birds logged in Gunung Leuser National Park (92 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.
