“Tris red or chestnut, bill blackish slate or slaty green, 
black on culmen, gape in youngish birds yellow, feet yellowish 
olive, yellowish green or greenish slate.” 
Very common up to about 5,000 feet, after which it 
rapidly became scarcer ; travelling in small parties among the 
thick undergrowth and low shrubs and uttering a very 
pleasant little song. 
This small Babbler belongs to a section of the genus very 
characteristic of the submontane zone of the Indo-Malayan 
countries and all the species ranging from the Himalayan 
S. nigriceps to the Bornean S. borneensis are very closely 
related. The present form is the most richly coloured of all 
and has the feathers of the under surface with somewhat 
lighter centres, giving an obscurely streaked effect. 
The grey of the chin and throat varies greatly in tint, 
being very pale in some and almost black in a few specimens.
