LC
Snowcap Microchera albocoronata



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). 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 is very large, and hence does not 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 is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2022). The species is described as uncommon to locally common (Stotz et al. 1996, Kistler and Schulenberg 2020).

Trend justification
Local declines are suspected to occur as a consequence of habitat loss (del Hoyo et al. 1999, Kistler and Schulenberg 2020). Tree cover within the range has been lost at a rate of 5% over the past ten years; since 2016 this has been accelerating to a rate equivalent to 9% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is commonly found in open, secondary and converted habitat and thus appears to tolerate some forest loss and degradation (Kistler and Schulenberg 2020). Population declines are therefore likely low; they are here placed in the band 1-9% over ten years.
