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 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.
