Geographic Range
[top]
| Range Description: |
Siptornopsis hypochondriaca occurs on the slopes above the dry upper río Marañón valley in south Amazonas, south-east Cajamarca, east La Libertad and north Ancash (one specimen taken in 1932), north Peru (Ridgely and Tudor 1994). It is currently known from four locations: around Balsas (Amazonas/Cajamarca) (Clements and Shany 2001), above Chagual (La Libertad) (J. Hornbuckle in litt. 1998) and at two sites near San Marcos (Cajamarca) (N. Simpson in litt. 2000, Begazo et al. 2001). There is suitable habitat along the Cajabamba-San Marcos road from Ichocan to the Rio Crisnejas, but none on the Cajabamba side of the river (N. Simpson in litt. 2000, H. Lloyd in litt. 2007). It may be locally common in less disturbed areas (H. Lloyd in litt. 2007).

| Population: |
The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Habitat and Ecology
[top]
| Habitat and Ecology: |
It inhabits arid/desert scrub and low dry forest, often with Acacia trees, at elevations of 2,000-3,000 m (Braun and Parker 1985, J. Hornbuckle in litt. 1998, N. Simpson in litt. 2000). Stream gullies with running water seem to be preferred at one site, where there were also numerous stacks of cut firewood (N. Simpson in litt. 2000). The positive or negative effects of cutting for firewood on the species are unknown (N. Simpson in litt. 2000).

| Major Threat(s): |
It is highly likely that this species's habitat is under pressure (Fjeldså and Krabbe 1990). The Marañón drainage has been under cultivation for a long time and habitat in the valley has progressively deteriorated. The spread of oil-palms, cattle-ranching and logging are all serious threats to remaining habitat, with oil extraction a potential future problem (Dinerstein et al. 1995).
