Maranon Crescentchest Melanopareia maranonica

Justification
This species has a small range, within which it is uncommon and probably declining. Future increases in human encroachment within the range could place this species at higher risk of severe declines. 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)

Taxonomic note
Melanopareia elegans (Sibley and Monroe 1990, 1993) has been split into M. elegans and M. maranonica following SACC (2005).

Distribution and population
Melanopareia maranonica occurs in north-west Peru (local in the upper río Marañón valley of Cajamarca) and extreme south Ecuador (Zumba region of south Zamora-Chinchipe) (Ridgely and Tudor 1994).

Population justification
The population size of this species has not been quantified, but it is described as local and uncommon.

Trend justification
Data on population trends are lacking, but declines are suspected owing to rates of habitat loss.

Ecology
It is uncommon and local in dry deciduous forest, arid lowland scrub and riparian thickets at 200-800 m, where it apparently tolerates a degree of disturbance (Ridgely and Tudor 1994, Parker et al. 1996, Stattersfield et al. 1998, R. Webster and R. A. Rowlett in litt. 1998).

Threats
Its habitat in the Marañón drainage has progressively deteriorated during a prolonged period of cultivation (Ridgely and Tudor 1994), while the spread of oil palm plantations, cattle-ranching and logging are all serious threats within its small range (Dinerstein et al. 1995). Oil extraction is a potential future problem (Dinerstein et al. 1995).

Conservation Actions Underway
Conservation Actions Proposed
Conduct ecological studies to determine whether this species can genuinely tolerate secondary or disturbed habitats. Re-visit known localities to determine rates of population change and habitat loss. As a precaution, protect significant areas of suitable habitat.
