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 →

With luck
About 10% of wildlife watchers report an Ashy Tailorbird sighting in Jakarta on a given day, based on 85 verified sightings from GBIF citizen-science data. It is the 53rd most-seen of the 138 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report an Ashy Tailorbird in Jakarta on a given day, against under 5% in February and November, the lowest months. That is one of Jakarta's driest months, with about 85 mm of rain against 370 mm in February.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Ashy Tailorbird sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.

Of the 9 cities where we can rate Ashy Tailorbird sightings, Jakarta ranks 7th at about 10%. The best odds are in Ho Chi Minh City (Vietnam, about 50%), Kuching (Malaysia, about 30%) and Cần Thơ (Vietnam, about 20%).
Same genus: Orthotomus

GBIF citizen-science records
It is estimated from how often the Ashy Tailorbird is recorded against all the birds logged in Jakarta (85 verified sightings), 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.
