Population justification: The population is estimated to number 10,000-40,000 individuals, divided into more than five subpopulations, each of which is fragmented and declining. This range roughly equates to 6,600-27,000 mature individuals. Estimates of population density in the Venezuelan llanos vary, with 80-160.7 individuals / km2 in riparian forest and 2.7-43.7 individuals / km2 in dry forest, both in the dry season.
Trend justification: A slow and on-going population decline is suspected owing to hunting for food and sport and habitat loss and fragmentation.
