Geographic Range [top]

Range Description:Hemitriccus rufigularis occurs disjunctly in the east Andes of Ecuador (west Napo, Morona-Santiago, Sucumbíos [T. Schulenberg in litt. 2001] and Zamora-Chinchipe), Peru (San Martín and from Huánuco south to Puno) and west Bolivia (La Paz, extreme south-west Beni and west Santa Cruz) (Ridgely and Tudor 1994). It is uncommon and very local.

Population [top]

Population:The population is preliminarily estimated to number at least 10,000 individuals, roughly equating to 6,700 mature individuals. This requires confirmation.

Trend Justification:  This species is suspected to lose 11.3-11.6% of suitable habitat within its distribution over three generations (11 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:6700Continuing decline of mature individuals:Unknown
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No
No. of individuals in largest subpopulation:100

Habitat and Ecology [top]

Habitat and Ecology:It appears to be restricted to vine tangles within humid foothill forest on isolated low massifs at 750-1,500 m (Ridgely and Tudor 1994; Parker et al. 1996; Ridgely and Greenfield 2001; Schulenberg et al. 2007).

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):3.6
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): In Peru, much of its habitat is relatively intact above 900 m, but there has been widespread destruction of foothill forests elsewhere in its range (Ridgely and Tudor 1994), where the effects of extensive agricultural conversion and logging have been amplified by road-building and human colonisation (Dinerstein et al. 1995).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Designate and effectively protect areas of foothill forest within its range. Promote conservation of forests among local people. Study the species's ecology and determine its ability to persist in degraded and fragmented habitats. Survey suitable habitat within its potential range. Attempt to quantify any declines in population.
