LC
Plain-winged Woodcreeper Dendrocincla turdina



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 under 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). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). 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 (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 9.2% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.

Distribution and population

This species occurs in eastern and southeastern Brazil (from eastern Bahia, south along the coast to northern Rio Grande do Sul, extending inland to southern Goiás, wesatern Paraná and western Santa Catarina), and eastern & central Paraguay and northeastern Argentina (Misiones and northeastern Corrientes).

Ecology

The species primarily inhabits humid and evergreen forest in the lowlands and foothills to 2000m, although generally below 1300 m, and is found less frequently in gallery and deciduous forest, and occasionally in mangroves. It is mainly insectivorous, although other invertebrates and small vertebrates are also taken (Marantz et al. 2003).

Threats

The species is considered highly sensitive to habitat fragmentation and human disturbance in at least parts of its range, and is likely to have suffered declines owing to deforestation (Marantz et al. 2003).
