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 →

GBIF citizen-science records
It is estimated from how often the Long-tailed Sibia is recorded against all the birds logged in Namdapha National Park (533 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.
