LC
Elusive Antpitta Grallaria eludens

Justification
This species is classified as Least Concern as it is not thought to approach the thresholds for any of the IUCN criteria; however, further research is required on this poorly-known species.

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

Distribution and population
Grallaria eludens occurs in south-east Peru in Ucayali (Balta and on the Cordillera Divisor), and probably Madre de Dios (Manu National Park and Cerro Pantiacolla (P. Champlin in litt. 1998)), and has recently been discovered on the upper rio Juruá, Brazil (Whittaker and Oren 1999).

Population justification
The global population size has not been quantified, but this species is described as 'rare'.

Trend justification
This species is suspected to lose 5.7-5.9% of suitable habitat within its distribution over three generations (11 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 <25% over three generations.

Ecology
It occurs in humid terra firme forest with dense undergrowth, from 150 to 500 m (Ridgely and Tudor 1994, Parker et al. 1996). It is otherwise essentially unknown (Ridgely and Tudor 1994, Parker et al. 1996).

Threats
Although its forests within its range are still relatively intact ( Stattersfield et al. 1998), the region is subject to some selective logging and is being opened up for development, with oil/gas extraction and mining, and associated road-building and human colonisation resulting in further degradation (Dinerstein et al. 1995).

Conservation Actions Underway
It occurs in Manu National Park, Peru.

Conservation Actions Proposed
Conduct ecological studies to determine this species's precise habitat requirements. Ensure that remaining tracts of suitable habitat receive adequate protection.
