LC
Black-crested Coquette Lophornis helenae



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 may be moderately small to large, 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 is suspected to number fewer than 50,000 mature individuals (Partners in Flight 2022), thus it is here placed in the band 20,000-49,999 mature individuals.

Trend justification
The population trend has not been investigated. Tree cover within the range is lost at a rate of 13% over ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests and forest edge, the species is also found in forest gaps and shrubby habitat and appears to be somewhat tolerant of degradation and disturbance (Arizmendi et al. 2020); consequently, population declines may be slower than the current rate of tree cover loss suggests. Tentatively, population declines are here placed in the band 1-9% over ten years.
