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 →

Likely
About 50% of wildlife watchers report a Yellow-bellied Fairy-Fantail sighting in Namdapha National Park on a given day, based on 866 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 298 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 80% of wildlife watchers report a Yellow-bellied Fairy-Fantail in Namdapha National Park on a given day, against about 10% in April, the lowest month. That is one of Namdapha National Park's driest months, with about 50 mm of rain against 660 mm in July. June to September have too few records to rate.
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.
Yes
Of the 7 parks where we can rate Yellow-bellied Fairy-Fantail sightings, Namdapha National Park has the highest daily chance: about 50%. Next come 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 Namdapha National Park (866 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.
