Justification:
This species has a small range and numbers are likely to be declining owing to habitat loss. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

History:

2008	–	Near Threatened
2004	–	Near Threatened

Geographic Range [top]

Range Description:	Grallaricula loricata occurs in the mountains of the Sierra de Aroa, Yaracuy and along the Cordillera de la Costa from Carabobo and Aragua to Distrito Federal, north Venezuela (Meyer de Schauensee and Phelps 1978, Ridgely and Tudor 1994, Hilty 2003).

Population [top]

Population:	The global population size has not been quantified, but this species is described as uncommon. However, since its easily-overlooked song was first recorded in 2004, it has been seen regularly at several different locations within Henri Pittier National Park (Sharpe in litt. 2011). During surveys in suitable habitat, it was found to be common, comprising 2.4-3.5% of the bird community and being recorded in 80-83% of surveys.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This species is locally common (Verea 2004, C. J. Sharpe in litt. 2011, Verea and Solórzano 2011) in the lower growth of montane humid forest at elevations of 1,200-2,100 m, although mostly at 1,440-1,700 m (Ridgely and Tudor 1994, Hilty 2003). It feeds on small arthropods such as crustaceans (Isopoda), arachnids (Aranae), and insects (Orthoptera, Hemiptera, Coleoptera and Hymenoptera) (Verea 2004). The species is thought to be monogamous, and breed from March to November, with moulting taking place from August to December (Verea 2004).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Although there is still extensive forest cover in parts of its limited range, deforestation has been severe around Caracas, and many other areas have been degraded (Huber and Alarcón 1988, Stattersfield et al 1998).
