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.
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).
A moderately rapid and on-going decline is suspected owing to habitat loss.
Phylloscartes oustaleti occurs in east Brazil at Boa Nova, Bahia (Tobias et al. 1993), and Espírito Santo south to east Rio Grande do Sul (Sick 1993, Ridgely and Tudor 1994). Although primarily known from the Serra do Mar, it is locally uncommon to fairly common throughout its range.
It is resident in the canopy, subcanopy and borders of mid-altitude evergreen forest, typically at 500-900 m, but locally to lower altitudes (Ridgely and Tudor 1994, Parker et al. 1996).
Agricultural conversion and deforestation for mining and plantation production historically threatened its lowland forests (Fearnside 1996). Current key threats are urbanisation, industrialisation, agricultural expansion, colonisation and associated road-building (Dinerstein et al. 1995).
Conservation Actions Underway
It occurs in several protected areas, including Augusto Ruschi Biological Reserve, Intervales State Park and Mata dos Godoy State Park.
