The long-tailed sibia (Heterophasia picaoides) is a species of Leiothrichidae from Southeast Asia. The species was once placed in the large family Timaliidae, but that family is sometimes split with this species being placed with the laughingthrushes in the family Leiothrichidae. The species is sometimes treated as the only species in the genus Heterophasia, with the other species being placed in the genus Malacias.
The long-tailed sibia is found from the Himalayas through South East Asia and Sumatra. It is found in evergreen forest, oak and pine forests, secondary growth, scrub with large trees and forest edge habitats. Wikipedia →

With luck
About 10% of wildlife watchers report a Long-tailed Sibia sighting in Royal Manas National Park on a given day, based on 190 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 101st most-seen of the 388 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March and July
In those months about 30% of wildlife watchers report a Long-tailed Sibia in Royal Manas National Park on a given day, against about 10% in February, April–June and October–November, the lowest months. Those are among Royal Manas National Park's wettest months, with about 520 mm of rain a month against 10 mm in December. August and September have too few records to rate.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Long-tailed Sibia sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
2nd of 3
Of the 3 parks where we can rate Long-tailed Sibia sightings, Royal Manas National Park ranks 2nd at about 10%. The best odds are in Namdapha National Park (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Long-tailed Sibia is recorded against all the birds logged in Royal Manas National Park (190 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.
