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 →

Rare
Under 5% of wildlife watchers report a Yellow-bellied Fairy-Fantail sighting in Kathmandu on a given day, based on 57 verified sightings from GBIF citizen-science data. It is the 181st most-seen of the 312 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Yellow-bellied Fairy-Fantail in Kathmandu on a given day, against under 5% in January to November, the lowest months. That is one of Kathmandu's driest months, with about 5 mm of rain against 280 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.
2nd of 2
Of the 2 cities where we can rate Yellow-bellied Fairy-Fantail sightings, Kathmandu ranks 2nd at under 5%. The best odds are in Dehradun (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow-bellied Fairy-Fantail is recorded against all the birds logged in Kathmandu (57 verified sightings), 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.
