Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01

This species has a very 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 has not been quantified, 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.

Geographic Range [top]

Range Description:This taxon comprises three subspecies, two of which are restricted to single mountain ranges (Strahl et al. 1994). The nominate race is uncommon to fairly common in north Colombia, although there are few recent records (P. G. W. Salaman in litt. 1999), and north and west Venezuela. This subspecies has a population of less than 50,000 individuals, divided into several subpopulations, of which at least two are declining (Hilty and Brown 1986, Strahl et al. 1994, Strahl and Silva 1997). The race albicauda has a population of less than 10,000 individuals in the Sierra de Perijá in north-east Colombia and north-west Venezuela (Strahl et al. 1994). The race colombiana also has a population of less than 10,000 individuals and occurs in the Santa Marta mountains, north Colombia (Strahl et al. 1994).

Population [top]

Population:Strahl et al. (1994)

Trend Justification:  The population is suspected to be in decline owing to ongoing habitat destruction in parts of its range, especially Colombia (del Hoyo et al. 1994).
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Unknown
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:The species primarily inhabits dense montane evergreen forest in subtropical and upper tropical zones, often nesting in Rubraceae tree species, but is occasionally observed in tall secondary growth, coffee plantations and the upper edges of drier forest, at elevations of 800-2,400 m, and locally from 350-3,050 m (del Hoyo et al. 1994).
Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):5.7
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Populations in the Sierra de Perijá in north-east Colombia and north-west Venezuela (race albicauda) are threatened through deforested for cattle-ranching and narcotics cultivation (Stattersfield et al. 1998). Populations in the Santa Marta mountains, north Colombia (race colombiana) are threatened by agricultural expansion, logging, burning, illegal agriculture and retaliatory herbicide spraying by the government (Dinerstein et al. 1995, Stattersfield et al. 1998). Most subpopulations are threatened by hunting for food and habitat loss, with the nominate race hunted for sport, despite virtually all occurring within national parks or forest preserves (Strahl et al. 1994, Strahl and Silva 1997). Only 15% of the sierra's original vegetation remains unaltered, suggesting that the formal designation of protected areas has not provided effective protection (Stattersfield et al. 1998).
