There are records of Long-billed Thrush Zoothera monticola from Tibet, mainly near border with Nepal (Nyalam County, Shigatse Prefecture); one record also from near Ruili, Yunnan. Similar to Dark-sided Thrush Z. marginata, but with an even more oversized bill and larger size; darker also than Dark-sided and spotted not scaled below. Like Dark-sided, also found in thick, moist forest, but less tied to streams. Song two or three notes followed by long pause. — Craig Brelsford
