Based on a model of future deforestation in the Amazon basin, 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.

9-11 cm. Small, understorey, gleaning antwren showing some sexual dimorphism. Male is olive-brown above and grey below, with a black throat spotted white. Female in contrast is buff below, and a more yellowish olive-brown colour above, with darker flanks. Voice A short, evenly paced series of harsh downslurred notes, increasing in intensity and decreasing in pitch. Other brief, harsh vocalisations known.
The primary threat to this species is accelerating deforestation in the Amazon basin, with logging, mining, human colonisation and subsistence agriculture being the major drivers within the Guyana Shield (del Hoyo et al. 2003, Soares-Filho et al. 2006, Bird et al. 2011). This species is likely 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.
