Crescent-faced Antpitta Grallaricula lineifrons

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.

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
Grallaricula lineifrons is known from few localities on the west slope of the Central Andes in south Colombia (east Cauca), and on the east slope of the Andes in Ecuador (west Napo, south-east Carchi, Cañar and north Loja) (Lehmann et al. 1977, Ridgely and Tudor 1994). It is considered rare to locally uncommon within this range, although its cryptic habits may disguise its true status (Ridgely and Tudor 1994).

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

Trend justification
Data on trends are lacking, but declines are likely to be occurring, owing to on-going rapid habitat loss.

Ecology
It occurs in the undergrowth of epiphyte-clad montane evergreen forest, elfin forest and adjacent secondary woodland, on relatively steep slopes, at 2,900-3,400 m (Fjeldså and Krabbe 1990, Ridgely and Tudor 1994, Parker et al. 1996).

Threats
Although apparently well protected at two sites (in east Cauca and north Loja) (Wege and Long 1995), widespread and severe deforestation of montane forest within its range has occurred owing to agricultural expansion, and further degradation is projected (Stattersfield et al. 1998). Lowering of the tree-line through cutting and burning for pasture is a major threat in Ecuador (del Hoyo et al. 2003). Some parts of its range are also threatened by burning and timber extraction for charcoal (Freile and Santander 2005).

Conservation Actions Underway
It occurs in Purace National Park, Colombia, and Cayambe-Coca Ecological Reserve, Ecuador. Conservation Actions Proposed
Conduct surveys of suitable habitats within and surrounding the known range to determine its true distribution and abundance. Ensure that remaining tracts of suitable habitat receive adequate protection. Conduct studies to determine the level of tolerance of secondary habitats, particularly in areas where primary habitat is extirpated.
