The Yellow-billed Nuthatch (Sitta solangiae) is indigenous to the Eastern countries of China, Laos and Vietnam.
This species is known to exist in several widely separated areas: the Hoang Lien Son Mountains in northwest Tonkin, the Da Lat plateau in southern Annam, Vietnam, the Kon Tum plateau of Vietnam and southeast Laos, and Hainan Island, in southeast China, and the Xe Sap region in Laos.
There are recent records from Hainan, several localities on the Da Lat plateau, where surveys since 1990 have recorded small numbers.
Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
Because of its narrow, isolated ranges, it is found only locally and in small numbers in most territories, lending credibility to the assumption that there is a small global population. Habitat loss contributes to its near-threatened status.
The Yellow-billed Nuthatch is another tiny bird, only 12.5-13.5 cm (3.5-7.5 in) in length.
A solidly built bird, it has long, tapered wings, a short, rectangular tail and a straight, thin, yellow bill. The upperparts are white or gray with blue markings, while the underparts are brown.
The males and females are similar.
This bird feeds on the insects, nuts, small fruits, and berries found in its habitat.
