The yellow-bellied fantail (Chelidorhynx hypoxanthus), also known as the yellow-bellied fairy-fantail, is found in the Indian subcontinent, the Himalayas, and portions of Southeast Asia including Thailand, Vietnam, and Myanmar. It is an altitudinal migrant.
It is about 8 cm (3.1 in) in size. It is yellow below and has a black eye-stripe, white wing-bar and broad black tail tipped white. It used to be placed in the family of the fantails (Rhipiduridae), but DNA analysis has shown it to be a close relative of the fairy flycatcher and it has therefore been transferred to the Stenostiridae, in the revalidated monotypic genus Chelidorhynx.
It often gathers in mixed-species flocks, especially during winter, with leaf-warblers, tits, and black-faced warblers. Image at ADW Wikipedia →

With luck
About 10% of wildlife watchers report a Yellow-bellied Fairy-Fantail sighting in Jim Corbett National Park on a given day, based on 198 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 157th most-seen of the 368 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December and January
In those months about 20% of wildlife watchers report a Yellow-bellied Fairy-Fantail in Jim Corbett National Park on a given day, against under 5% in March to November, the lowest months. Those are among Jim Corbett National Park's driest months, with about 30 mm of rain a month against 360 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-bellied Fairy-Fantail sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 7
Of the 7 parks where we can rate Yellow-bellied Fairy-Fantail sightings, Jim Corbett National Park ranks 4th at about 10%. The best odds are in Namdapha National Park (India, about 50%), Doi Inthanon National Park (Thailand, about 40%) and Langtang National Park (Nepal, about 20%).
GBIF citizen-science records
It is estimated from how often the Yellow-bellied Fairy-Fantail is recorded against all the birds logged in Jim Corbett National Park (198 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.
