Population justification: The population is currently estimated to number between 8,500 and 10,000 individuals (P. Sepúlveda in litt. 2011), roughly equivalent to 5,700-6,700 mature individuals.
Trend justification: The species's population recovered rapidly following a ban on hunting in 1986. It has increased from an estimated low of 2,700 individuals to between 8,500 and 10,000 individuals today, although there is some fluctuation (Oliveira et al. 2007, Barov and Derhé 2011).
