Population justification: The population is estimated to number 1,000-10,000 individuals, roughly equating to 670-6,700 mature individuals.

Trend justification: The population is declining owing to habitat loss and degradation. The population may also be declining locally owing to Poisoning of carcasses and egg collecting (Ferguson-Lees and Christie 2001).
