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 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, but descriptions range from 'generally rare' (Greeney 2020) to 'fairly common' (Stotz et al. 1996).
Trend justification
Data on population trends are lacking, but declines are suspected on the basis of habitat destruction and human incursion into forest habitats. Over three generations (13.6 years), 2% of tree cover is lost within the range (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Despite additional negative impacts of habitat degradation, population declines are likely equally low and localised; they are here tentatively placed in the band 1-9% over three generations.
Pittasoma rufopileatum occurs in the Pacific lowlands of western Colombia south to north-west Ecuador.
This species inhabits the understory of humid forest up to 1,100 m, where it is usually seen following army-ant swarms (Ridgely and Tudor 1994, Greeney 2020). Its ecology is largely unknown.
Unplanned colonisation following the completion of roads, and massive logging concessions have cleared or degraded over 40% of original Chocó forests (Salaman 1994, Stattersfield et al. 1998). Currently, habitat loss through logging, human settlement, cattle-grazing, mining and coca and palm cultivation all pose threats (Dinerstein et al. 1995, Stattersfield et al. 1998).
Conservation Actions Underway
No targeted actions are known.
Conservation Actions Proposed
Survey suitable habitat within the range to locate additional populations. Produce an accurate quantification of the population size. Monitor the population trend. Protect areas of suitable habitat within the range.
