Geographic Range
[top]
| Range Description: |
Hemispingus rufosuperciliaris is restricted to the east Andes of north-central Peru. It is uncommon and locally distributed in the Cordillera de Colán, Amazonas, and the Cordillera Central, south to east La Libertad and the Carpish Mountains, Huánuco (Ridgely and Tudor 1989, Fjeldså and Krabbe 1990, Clements and Shany 2001).

Population

| Population: |
The population size is preliminarily estimated to fall into the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals. The species is rare and local throughout its range.

Habitat and Ecology
[top]
| Habitat and Ecology: |
It inhabits dense undergrowth in humid elfin forest near and just below the timberline, and shows a marked preference for extensive thickets of Chusquea bamboo (Ridgely and Tudor 1989). All records are at elevations of 2,500-3,500 m, but mostly above 2,800 m (Parker et al. 1996, Schulenberg et al. 2007). Birds tend to forage in pairs, perch-gleaning berries and insects in the undergrowth and on the ground (Ridgely and Tudor 1989, Fjeldså and Krabbe 1990). It occasionally associates with lower-storey, mixed-species flocks (Fjeldså and Krabbe 1990).

| Major Threat(s): |
Timberline habitats in the Andes have been diminishing since the arrival of humans thousands of years ago, primarily through the use of fire (Kessler and Herzog 1998). During the colonial period, sustainable land-use systems established by Pre-Columbian cultures were largely replaced with unsustainable agricultural techniques, including widespread burning (Kessler and Herzog 1998). Regular burning of páramo grassland, adjacent to elfin forest, to promote the growth of fresh shoots for livestock, has lowered the treeline by several hundred metres, and continues to destroy large areas of this species's habitat (Kessler and Herzog 1998). The human population density in large areas of the species's range is low (T. S. Schulenberg in litt. 1999), indicating that some of its populations may be relatively secure at present, however there is a marked increase in number of cattle in northern Peru (J. Fjeldså in litt. 2007). In more populated areas, small, fragmented remnants of elfin forest are additionally threatened by clearance for agriculture and grazing, with an alarmingly high rate of conversion to cash-crops in the (until relatively recently pristine) Cordillera de Colán (Barnes et al. 1995, Kessler and Herzog 1998).

It presumably occurs in Río Abiseo National Park.
Conservation Actions Proposed
Survey to determine more accurately its distribution. Confirm existence in Río Abiseo National Park. Improve land-use management by segregating agricultural, grazing and forest areas (Fjeldså and Kessler 1996). Regulate the use of fire (Fjeldså and Kessler 1996). Reintroduce old, high-yielding agricultural techniques (Fjeldså and Kessler 1996). Encourage local people to take a leading role in land-use management and restoration schemes (Fjeldså and Kessler 1996).
