G. R. Gray, 1859,
northern India = Darjeeling, Sikkim.
Resembles B. moniliger in coloration and pattern, and the two species replace each other geographically, but differences in facial bristles, clutch size, egg size and adult plumage markings suggest that they are probably too dissimilar to be regarded as being very closely related. Sometimes treated as a race of B. javensis, but differences in bill size and structure, development of facial bristles, relative tail length and vocalizations, and also perhaps bare-part colours (bill said to be darker) too great for the two to be considered conspecific or even as very close. Validity of allegedly smaller and shorter-tailed race indochinae sometimes questioned, as measurements overlap with those from NE Indian individuals. Birds from Manipur (NE India) described as race rupchandi, but apparently inseparable from other Indian populations. Two subspecies recognized.
