Mottled Piculet Picumnus nebulosus


Justification of Red List Category
This species is classified as Near Threatened because it is suspected to be declining moderately rapidly owing to habitat loss.

Population justification
The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).

Trend justification
A moderately rapid and on-going population decline is suspected owing to habitat loss.

Distribution and population

Picumnus nebulosus occurs in south-east Brazil, from Paraná south to Rio Grande do Sul, in adjacent parts of Uruguay, and in Misiones and Corrientes, north-east Argentina, where there are few recent records (Chebez 1994, Winkler et al. 1995).


It is found up to 1,100 m in lowland evergreen and mixed Araucaria forests with dense undergrowth (often in bamboo areas, despite not directly depending on this microhabitat), forest edge and gallery woodland (Belton 1984, Parker et al. 1996, Naka et al. 2000).


Agricultural conversion and deforestation for mining and plantation production historically threatened its lowland forests. Current key threats are urbanisation, industrialisation, agricultural expansion, colonisation and associated road-building (Dinerstein et al. 1995, Fearnside 1996). The proposed Garabí dam on the río Uruguay could flood the only forest patches from which it is currently known in Argentina (Chebez 1994).

Conservation actions

Conservation Actions Underway
It occurs in Aparados da Serra National Park in Brazil.

Conservation Actions Proposed
Effectively protect and manage protected areas where the species occurs. Monitor population at strongholds and search for the species in potentially suitable habitat at new sites. Study its ecology and its ability to persist in degraded and fragmented habitats. Use GIS habitat loss data to produce estimate of declines.
