Green-tailed Emerald Chlorostilbon alice



Justification

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). The population trend appears to be stable, and hence does not approach the thresholds 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 this species is described as locally common (Bündgen et al. 2020).

Trend justification
Vast areas of pristine forests remain across the species' range (Global Forest Watch 2022). The species also readily accepts man-made habitats such as plantations, parks, gardens and roadsides where stands of shrubs and trees are found (Bündgen et al. 2020). Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.

Distribution and population

This species is endemic to montane regions of northern Venezuela (Bündgen et al. 2020).

Ecology

The species can be found in edges of rainforest and cloudforest, as well as secondary growth forests, plantations, parks, gardens and roadsides (Bündgen et al. 2020). It readily accepts man-made habitats and is rarely found in dense forest. The species occurs at elevations between 700-1,800 m. It forages on various flowering shrubs and small trees including Leguminosaceae, Rubiaceae, Gesneriaceae and Ericaceae, only occasionally feeding on insects. The breeding season lasts from January to March (Bündgen et al. 2020).

Conservation actions

Conservation Actions Underway
The species is present in the following Endemic Bird Areas (EBA); Caripe-Paria Region EBA, Cordillera de la Costa Central EBA, and Cordillera de Mérida EBA (Bündgen et al. 2020). 

Conservation Actions Proposed
Monitor population trends and quantify the population size. Research potential threats and their possible impacts.
