Xinjiang Ground-jay Podoces biddulphi

Justification
This species is considered Near Threatened as it is likely to have a moderately small and fragmented global population size, and is inferred to be in decline owing to habitat fragmentation and degradation. Further studies are required to clarify the current magnitude of risk to this species.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Podoces biddulphi is known from Xinjiang, western China, where it occurs in the Taklimakan Desert (and there is a recent sight record well to the east of this area, near Golmud in Qinghai) (BirdLife International 2001). It was described as being common in 1929-1930, but it was scarce and difficult to locate in the same areas in 1988. However, it has recently been found to be widespread and locally common in the interior of the Taklimakan Desert.

Population justification
The total population of this species is estimated to number c.10,700 individuals, equivalent to c.7,133 mature individuals.

Trend justification
Precise data on population trends are not available, but a slow to moderate decline is suspected to be occurring as a result of habitat conversion and degradation.

Ecology
This species is found in sandy desert, scrub and desert poplar.

Threats
This species is probably declining because of the fragmentation and degradation of desert habitats through the intensive grazing of goats and camels, extraction of fuelwood and the conversion of huge areas to irrigated land.

Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.

Conservation Actions Proposed
Conduct repeated surveys within the species's range to determine its current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements. Effectively protect significant areas of suitable habitat, especially desert poplar, at key sites.
