Tibetan Babax Garrulax koslowi


Justification of Red List Category
This species is considered Near Threatened as it has a restricted range, within which is it scarce and therefore assumed to have a moderately small global population size. Although it is not thought to be declining at present, it should be monitored carefully in case of any future increases in threats.

Population justification
The global population size has not been quantified, but the species is described as rather scarce and localised (del Hoyo et al. 2007).

Trend justification
There is no evidence of any decline at present, although some logging is reported to be occurring within the range, and any increases in human population pressure could lead to declines in the future.

Distribution and population

Babax koslowi is restricted to the eastern part of the Qinghai-Tibetan Plateau, in eastern Tibet and southern Qinghai, China, where several large valleys cut into the plateau, including those of the Tongtian river (the upper reaches of the Chang Jiang or Yangtze), the Lancang Jiang (the upper Mekong) and the Nu Jiang (the upper Salween). It is known by just a few scattered records in this inaccessible and poorly known area, but it appears to be genuinely rather scarce and localised.


This species is found in juniper forest and scrub, mixed fir and juniper forest and scrub bordering agricultural land at c.3,650-4,500 m.


Some logging of forest is occurring within the range of this species, but rates are slow and it does not appear to be immediately threatened by habitat loss.

Conservation actions

Conservation Actions Underway
No targeted conservation actions are known for this species.

Conservation Actions Proposed
Monitor populations and habitat trends across its range. Conduct ecological studies to determine precise habitat requirements and response to fragmentation. Protect areas of suitable habitat and safeguard against future threats.
