White-lined Antbird Percnostola lophotes

Justification

Based on a model of future deforestation in the Amazon basin, and its particular susceptibility to forest fragmentation, it is suspected that the population of this species will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.

Taxonomic source(s)
SACC. 2006. A classification of the bird species of South America. Available at: #http://www.museum.lsu.edu/~Remsen/SACCBaseline.html#.

Identification
14-15 cm. Medium-sized, sexually dimorphic antbird. Has a prominent crest. Male is blackish grey, darkest on the head and breast. Female is yellow-brown above and white below.

Distribution and population
Percnostola lophotes has a restricted range within western Amazonia. It occurs in western Acre, in extreme south-west Amazonian Brazil, including parts of the Serra do Divisor National Park. In south-east Peru, it is found in east Junín, Cuzco, Madre de Dios and Puno, known to be present in Manu National Park and Biosphere Reserve, and Tambopata-Candamo Reserved Zone. Its range extends to Pando and northern La Paz, in north-west Bolivia, including occurrence in Madidi National Park (del Hoyo et al. 2003).

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

Trend justification
This species is suspected to lose 16.4-17.6% of suitable habitat within its distribution over three generations (14 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to fragmentation and/or edge effects, it is therefore suspected to decline by a rate approaching 30% over three generations.

Ecology
This is an understorey species of river edges in "várzea" (seasonally flooded forest) and transitional forest, usually characterised by the presence of Cecropia, Ochroma and Erythrina trees. It prefers lowlands below 750 m, with occasional records from up to 1,450 m (del Hoyo et al. 2003).

Threats

The primary threat to this species is accelerating deforestation in the Amazon Basin (Soares-Filho et al. 2006, Bird et al. 2011). It is thought to be particularly susceptible to forest fragmentation and edge effects (A. Lees in litt. 2011). Proposed changes to the Brazilian Forest Code reduce the percentage of land a private landowner is legally required to maintain as forest (including, critically, a reduction in the width of forest buffers alongside perennial steams) and include an amnesty for landowners who deforested before July 2008 (who would subsequently be absolved of the need to reforest illegally cleared land) (Bird et al. 2011).

Conservation Actions Underway
None is known.

Conservation Actions Proposed

Expand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006). Campaign against proposed changes to the Brazilian Forest Code that would lead to a decrease in the width of the areas of riverine forest protected as Permanent Preservation Areas (APPs), which function as vital corridors in fragmented landscapes
