Population justification: S. Subramanya (in litt. 2006) has suggested that the population in South India now exceeds 5,000 birds owing to increases resulting from improved protection of the species, and the latest figures from Andhra Pradesh and Telangara suggest that there are >10,000 individuals in those states alone (H. Taher in litt. 2016). The global population is currently placed in the range 13,000-18,000 individuals globally, roughly equivalent to 8,700-12,000 mature individuals, though this may require revising upwards in the future.
Trend justification: The species declined rapidly during the 20th century, but in recent years the population appears to have stabilised, with at least some populations apparently now increasing in response to improved protection (P. Round in litt. 2006, S. Subramanya in litt. 2006, 2016, H. Taher in litt. 2016). The global population is suspected to have undergone a moderately rapid decline over the last three generations.
