Olive-backed Quail-dove Leptotrygon veraguensis


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 threshold 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
Partners in Flight (2019) consider the population size to be <50,000 mature individuals (see also Panjabi et al. 2019). It is placed here in the range 20,000-49,999 mature individuals.

Trend justification

The species is undergoing a moderate decline (Partners in Flight 2019). A remote sensing study found that forest within the range has been lost at a rate of 4% over three generations (Tracewski et al. 2016); thus the species may be declining by < 10% over three generations.
