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.

Rare
Under 5% of wildlife watchers report a Slender-billed Babbler sighting in Kaziranga National Park on a given day, based on 78 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 191st most-seen of the 323 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–May and October
In those months about 10% of wildlife watchers report a Slender-billed Babbler in Kaziranga National Park on a given day, against under 5% in August–September and November–February, the lowest months. June and July have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Slender-billed Babbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Slender-billed Babbler sightings, Kaziranga National Park ranks 3rd at under 5%. The best odds are in Manas National Park (India, about 10%) and Chitwan National Park (Nepal, about 10%).
GBIF citizen-science records
It is estimated from how often the Slender-billed Babbler is recorded against all the birds logged in Kaziranga National Park (78 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.
