LC
Cocoa Woodcreeper Xiphorhynchus susurrans



Justification

Justification of Red List Category
This species has an extremely 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 estimated to number 500,000-4,999,999 mature individuals (Partners in Flight 2019). The species is described as fairly common to common throughout most of its range, although uncommon to rare at higher altitudes, in north-west Costa Rica and in northern Honduras (del Hoyo et al. 2003).

Trend justification

The species is undergoing a moderate decline (Partners in Flight 2019), which is thought to be caused by low levels of habitat loss within the range (Tracewski et al. 2016).
