Justification of Red List category
This species has a large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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 size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). 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 (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996) and 'generally common' (del Hoyo et al. 1999). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 0.8% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being less than 5%.
Trend justification
.
The species occurs in the Andes of Venezuela, Colombia, Ecuador, Peru and Bolivia.
The species is found predominantly in wet and humid montane forests (cloud forest and elfin forest), and to a lesser extent in forest-edge, bushy second growth, open bushy terrain along streams and humid grassy slopes, from 1,800-3,200 m (Schuchman 1999). It forages in the low and middle strata, feeding on nectar and insects.
Conservation Actions Underway
The species is protected within reserves in many areas throughout its extensive range, for instance in Cordillera Azul, Apurímac (Peru), and Beni (Bolivia).
