Population justification: Winter counts in 2015 recorded 7,464 individuals in Paraná and 1,712 in São Paulo with both populations continuing to increase (D. Waugh in litt. 2015). The population is therefore estimated to number 9,000-10,000 individuals, roughly equating to 6,000-6,700 mature individuals.

Trend justification: Long-term conservation measures are suspected to have contributed to a recent population increase, although habitat fragmentation and poaching remain significant threats (Waugh 2006).
