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 40% of wildlife watchers report a Yellow-bellied Fairy-Fantail sighting in Doi Inthanon National Park on a given day, based on 1,453 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 367 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
June and July
In those months about 60% of wildlife watchers report a Yellow-bellied Fairy-Fantail in Doi Inthanon National Park on a given day, against about 30% in April, the lowest month. Those are among Doi Inthanon National Park's wettest months, with about 300 mm of rain a month against 20 mm in February.
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.
2nd of 7
Of the 7 parks where we can rate Yellow-bellied Fairy-Fantail sightings, Doi Inthanon National Park ranks 2nd at about 40%. The best odds are in Namdapha National Park (India, about 50%).
GBIF citizen-science records
It is estimated from how often the Yellow-bellied Fairy-Fantail is recorded against all the birds logged in Doi Inthanon National Park (1,453 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.
