English: The yellow-bellied fantail, also referred to as the yellow-bellied fairy-fantail, is a bird species native to the Indian subcontinent, the Himalayas, and parts of Southeast Asia, including Thailand, Vietnam, and Myanmar. Measuring around 8 cm in length, this energetic little bird is distinguished by its bright yellow belly and pale-tipped, fan-shaped tail.

The yellow-bellied fantail is commonly found in foothill and submontane broadleaf forests, where it forages actively and acrobatically in the middle and lower forest levels. It often joins mixed-species foraging flocks with fulvettas, warblers, and other small passerine birds. Although similar in shape to fantails, it is much smaller and more closely related to tits. The bird's vocalizations include a series of high-pitched "tsit" notes, as well as twitters and trills. Its call, often repeated over an extended period, consists of a series of high "tsip" notes, which can resemble its song but is generally simpler in composition.
