Population justification: The population estimate of 2,500-9,999 individuals is derived from P. G. W. Salaman in litt. (1999). This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals. The population in Venezuela has been recently estimated at approximately <1,000 individuals (C. J. Sharpe in litt. 2015).
Trend justification: A slow and on-going population decline is suspected owing to habitat loss and possibly egg-collecting and hunting.
