Population justification:

The population size has not been quantified, however Praveen et al. (2015) suggested that the species may be considered a regular inhabitant given the number of records within Meshai, Anjaw, Arunachal Pradesh. Similarly, Grimmet et al. (1998) note the species' common in Arunachal Pradesh. MacKinnon and Phillips (2000) further describe the species as abundant in hill and montane forests across Tibet, south-west Sichuan, and west and north-west Yunnan up to 4,000 m.

Trend justification:

The population is suspected to be undergoing a slow decline due to trapping for the pet trade for both national and international markets. MacKinnon and Phillipps (2000) claim the species is often captured at nests for the pet trade, contributing to its local endangerment.This is evidenced by the presence of P. derbiana in both national bird markets, e.g. Guiyang, South-West China (Dai and Zhang 2017), as well as international markets e.g. in Algeria for $2044 per individual (Idir et al. 2023), in the West Bank, Palestine (Handal et al. 2023), in Singapore (Eaton et al. 2017) and Taiwan (J. Eaton in litt. 2024). Whilst it is not entirely clear if these are wild caught or captive bred individuals, the implication that the species is considered highly valuable and sold both nationally and internationally persists. Despite this, the rate of decline is not thought to be rapid. In most cases only one to two individuals are being sold at a market. Additionally, the species is evidently commonest at remote high altitudes where there is minimal exploitation. Despite that some areas seem to have an abundance of the species, local extinctions and declines in the past (J. Eaton in litt. 2010, He Fen-Qi in litt. 2010, J. Hornskov in litt. 2010, Zeidler and Francis 2011) suggest that the species is in decline overall.
