Justification

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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not 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.

Population justification
The global population is estimated to number 50,000-499,999 mature individuals (Partners in Flight 2019).

Trend justification
The population is undergoing a large, significant decline (Partners in Flight 2019).

Identification

Amaurolimnas concolor has a range spanning much of Latin America. It occurs in Mexico, Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Venezuela, Guyana, French Guiana, Suriname, Brazil, Peru and Bolivia. The nominate subspecies of Jamaica was driven to extinction by introduced mongooses in the late 1800s (del Hoyo et al. 1996).
