LC
Short-tailed Parrotbill Neosuthora davidiana



Justification

Justification of Red List Category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as locally common in China and Vietnam and very scarce and difficult to observe in other locations (del Hoyo et al. 2007). Brazil (2009) estimates the population in China at c.100-10,000 breeding pairs.

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation. However, recent fieldwork has revealed that this species is far more common than previously believed, and is able to tolerate degraded habitats (BirdLife International 2001).
