Justification of Red List Category
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.
The global population size has not been quantified, but this species was described as 'fairly common', before being split (Stotz et al. (1996).
The population is suspected to be in decline owing to ongoing habitat destruction.
Subspecies T. p. parzudakii occurs in SW Venezuela (Andes of SE Táchira); E Andes of Colombia (W slope from Santander to Cundinamarca and head of Magdalena Valley in Huila; E slope probably throughout, but recorded only Meta, Caquetá, Putumayo and Nariño) and E slope in Ecuador. Subspecies T. p. urubambae occurs in E slope of Andes in Peru (S to Cuzco and Ayacucho).
