LC
Yellow-fronted Whitestart Myioborus ornatus



Justification

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 <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 is suspected to be stable and hence does not 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, however is considered common through its range (Curson et al. 2020).

Trend justification
Tree cover loss in the last 10 years has equated to less than 2% within the species range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). As such, the population is suspected to be stable.

Distribution and population

The species extends from extreme western Venezuela to the Southern and Eastern Andes of Colombia (Curson et al. 2020). The species was previously recorded in 1991 in Páramo de Tama (on the Venezuelan and Colombian border), in which four individuals were spotted. Ten individuals were also spotted in the same location in 1993 (Curson et al. 2020).

Ecology

The species occurs in montane, cloudforest, and elfin forested areas, generally at elevations of 2,100-3,400 m (Curson et al. 2020). The species feeds mainly on insects and other arthropods (Curson et al. 2020).

Threats

Tree cover loss in the last 10 years has equated to less than 2% within the species range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein).
