Pnoepyga, a genus of small birds known as cupwings or wren-babblers, consists of four species and is native to the montane regions of South and Southeast Asia. These birds were traditionally included in the babbler family Timaliidae, but a 2009 DNA study revealed that they did not fit in this family, nor in the Old World warblers' Sylviidae, leading to the creation of their own family, Pnoepygidae. The scaly-breasted cupwing ranges from north India to southern China and northern Vietnam, while the Taiwan cupwing is unique to Taiwan, and the Nepal cupwing is primarily found in Nepal, with some presence in India. The most widespread, the pygmy cupwing, can be found from China and India extending through Southeast Asia to the Malay Peninsula, and as far as Flores and Timor in Indonesia. Each species is adapted to life in the mountainous areas of their respective regions, displaying distinct patterns and behaviors suitable for their environments.
