Population justification: A total wild population of more than 250 individuals was estimated in 2011 (He Fenqi in litt. 2012), but the number of mature individuals of this colonial and cooperative breeder is conservatively estimated at fewer than 250.
Trend justification: This species remains poorly known and may prove to be more common than current evidence suggests. Data from its known colonies show mild population fluctuations, but a decline of unknown severity is suspected owing to low productivity and the threat of building developments to several colonies.
