The slender-billed babbler (Argya longirostris) is a species of bird in the family Leiothrichidae. It is found in Bangladesh, Nepal, Northeast India and possibly Myanmar. Its natural habitat is subtropical or tropical seasonally wet or flooded lowland grassland.
It is threatened by habitat loss. This species was formerly placed in the genus Turdoides but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus Argya.

With luck
About 10% of wildlife watchers report a Slender-billed Babbler sighting in Manas National Park on a given day, based on 184 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 130th most-seen of the 377 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Slender-billed Babbler is recorded against all the birds logged in Manas National Park (184 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.
