Tachira Antpitta Grallaria chthonia

  • Order: Passeriformes
  • Family: Grallariidae
  • Monotypic
  • Authors: Harold F. Greeney and Guy M. Kirwan


Conservation Status

Tachira Antpitta was not reported between the time that the original four specimens were collected in 1955 and 1956, and its rediscovery in June 2016, despite searches at the type locality in 1990 and 1996 (Collar et al. 1992, BirdLife International 2013), and its habitat remains under imminent threat from deforestation activities. Consequently the IUCN Red List conservation status of Tachira Antpitta is assessed as Critically Endangered (BirdLife International 2013).

Effects of human activity on populations

Apart from the ubiquitous assumption that this species will be detrimentally affected by habitat fragmentation, there are no specifically documented human threats to Tachira Antpitta. Given that one of its putative relatives, Scaled Antpitta (Grallaria guatmalensis), is able to inhabit and even breed in areas of high forest disturbance (Krabbe and Schulenberg 2003, Greeney et al. 2008, 2013). Nonetheless, there is extensive deforestation in the Río Chiquito, especially below 1600 m, and despite the nominal protections afforded by Parque Nacional El Tamá (Sharpe and Lentino 2008).
