Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2017
Date Assessed: 2017-10-01

This species has a small range, which may be undergoing a slow decline in extent, area and quality of habitat; and this may consequently may be causing the population to decline. However, the species is not thought to be severely fragmented or restricted to a limited number of locations and so the species is listed as Near Threatened.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species is restricted to Cerro Azul, Cerro Brewster, Cerro Bruja, Cerro Mali, Cerro Tacarcuna and Serranía de Majé of central and eastern Panama, as well as mountains of the extreme north-west Colombia (Schuchmann et al. 2017). Tracewski et al. (2016) estimated the maximum Area of Occupancy (calculated as the remaining tree area within the species’s range) to be c.1,291 km2, rounded here to 1,300 km2.
Countries occurrence:
Colombia; Panama

Population [top]

Population:The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. [1996]).

Trend Justification:  Deforestation rates suggest that this species could potentially be undergoing a slow decline (Tracewski et al. 2016), but given that the rate of forest loss is so slow (c.2.4% over 3 generations [c.12.5 years]) the species is only very tentatively assessed as declining.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:UnknownContinuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in humid forest at altitudes of between 600 and 1,200 m (see Schuchmann et al. 2017).
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):4.2
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): A slow amount of deforestation may be threatening this species (see Tracewski et al. 2016), but much of this habitat has not been affected by man yet (Schuchmann et al. 2017).
