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.
Population justification
The global population size has not been quantified, but the species is described as numerous in suitable habitat (Hilty et al. 2022).
Trend justification
The population is suspected to be in decline owing to ongoing habitat degradation and destruction.
This species has a rather patchy distribution in the Andes of central Ecuador to central Peru (Ridgely and Tudor 1989).
This species inhabits shrubbery, low woodland including Polylepis/Gynoxys groves and forest borders, from just below the timberline to well above it. It is mostly recorded from 3,000 to 4,000 m altitude (Ridgely and Tudor 1989). It is usually encountered singly or in pairs, and forages almost entirely by gleaning from the undersides of Gynoxys leaves, feeding on small insects and sugary secretions produced either by the insects or by the leaves (Isler and Isler 1987). It has also been observed feeding on nectar (Isler and Isler 1987). The nest is a tiny cup placed in a tree; fledglings have been found in May and July (Fjeldså and Krabbe 1990).
The widespread destruction of montane shrub and fragmentation of Polylepis woodlands through uncontrolled use of fire, firewood-collection, intense grazing (particularly with sheep and cattle), unsound agricultural techniques and afforestation with exotic tree species (especially Eucalyptus) presumably threatens this species (Fjeldså and Kessler 1996, Stattersfield et al. 1998).
Conservation Actions Underway
The species occurs in several protected areas. It is listed as Endangered at the national level in Ecuador (Freile et al. 2019).
Conservation Actions Proposed
Quantify the population size. Monitor the population trend. Protect areas of suitable habitat within the range.
