Sikkim Wedge-billed Babbler

The Sikkim wedge-billed babbler, or blackish-breasted babbler, is an Old World babbler named for the Indian state of Sikkim, found in the Indian subcontinent and nearby parts of South-east Asia. It inhabits the understorey of broadleaf evergreen forest and bamboo at 900–1,950m, favouring west-facing slopes in Bhutan, and is becoming rare through habitat loss (Wikipedia, general species account).

It occurs in small parties and feeds on insects, particularly woodlice and boring beetles. The source does not mention China (Wikipedia, general species account).
