Yellow-bellied Fantail

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. == Description == 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. == Classification == 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. == Social Behavior == It often gathers in mixed-species flocks, especially during winter, with leaf-warblers, tits, and black-faced warblers.
