Scientific Name: Herpsilochmus gentryi
Species Authority: Whitney & Alvarez Alonso, 1998
Common Name(s):
English Ancient Antwren

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Butchart, S., Gilroy, J., Sharpe, C J
Justification:
This habitat specialist is listed as Near Threatened as it is known from a small range, and is probably declining. It is likely to be at increased risk from human encroachment in the near future owing to rising population pressures within its range. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

Geographic Range [top]

Range Description: Herpsilochmus gentryi occurs in the Marañón, Tigre, Corrientes, Pucacuro and Pastaza drainages in north-central Peru (Loreto) and east Ecuador (Pastaza), where it is common at a moderate number of sites since its discovery in the mid-1990s. It was previously thought to occur only in two rare and patchy types of terra firme forest, growing on hill-top nutrient-poor soils, but a third type is apparently inhabited in Ecuador.

Population [top]

Population: The population size of this species has not been quantified, but it is described as locally common in general, being rare and local in Ecuador but locally fairly common in Peru.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs in canopy and subcanopy of humid tropical forest up to 200 m. Apparently restricted to terra firme forest growing on nutrient-poor podzolic or quartzitic soils, as well as on high, dry ridgetops.

Systems: Terrestrial

Threats [top]

Major Threat(s): In the Iquitos area, Peru, an increasing amount of its habitat is being cleared owing to human population growth. Much of the remainder of its range is remote and subject to little human pressure.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
It is well protected in Ecuador, by the Kapawi Ecological Reserve, whilst the Allapahuayo-Mishana Reserved Zone in Peru encompasses large areas of suitable habitat.

Conservation Actions Proposed
Conduct surveys of suitable habitats within and surrounding the known range to determine its true distribution and abundance. Increase the area of suitable habitat that has protected status, particularly near Iquitos.
