Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Wetlands International (2019) estimate the global population to number 20,000-85,000 mature individuals, while Partners in Flight (2019) estimate fewer than 50,000 mature individuals.
The population trend is difficult to determine. Wetlands International (2019) report stable trends for the population in central South America and unknown trends for the population in Central America and northern South America. Partners in Flight (2019) however list a small overall decline.
