Range DescriptionPsittacula derbiana occurs from Arunachal Pradesh and Assam, India, to southern China, including south-eastern Tibet, western Szechwan and western Yunnan (del Hoyo et al. 1997, Juniper and Parr 1998). Local extinctions and locally falling numbers (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.
