This species is classified as Vulnerable because it is known from few locations in a small range, where there is continuing habitat loss and degradation (Collar et al. 1992).

Geographic Range [top]

Range Description:Oreothraupis arremonops has a patchy distribution on the Pacific slope of the West Andes of Colombia (Antioquia, Valle del Cauca, Cauca, Nariño, Risaralda [Echeverry-Galvis and Córdoba-Córdoba 2007]) and north-west Ecuador (Pichincha and Imbabura). In Ecuador, there are modern records from the Tandayapa area, Pichincha, and Cotacachi-Cayapas National Park, Imbabura (M. S. Gregory in litt. 2001), Los Cedros Protected Forest and Mindo (Ridgely and Greenfield 2006, Freile and Santander 2005, Athanas and Greenfield 2016). The population in Munchique National Park, Cauca, is estimated to number 1,000 mature individuals, probably the global stronghold (P. G. W. Salaman in litt. 1999). Its apparent rarity may in part result from the inaccessibility of its very wet, often steep-sloped environment (P. G. W. Salaman in litt. 1999).

Population [top]

Population:The species is described as very rare and local. Its 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.

Trend Justification:  A slow and on-going population decline is suspected owing to rates of habitat loss.
Current Population Trend:Decreasing

Extreme fluctuations:NoPopulation severely fragmented:No
No. of subpopulations:2-100Continuing decline in subpopulations:Unknown

No. of individuals in largest subpopulation:1-89

Habitat and Ecology [top]

Habitat and Ecology:This poorly-known species inhabits thick undergrowth in primary humid forest (mostly dense, wet, mossy cloud-forest) between 1,200 and 2,800 m altitude. In Cauca, it is most frequently observed between 2,300 and 2,500 m. It has been observed in areas with abundant Clusia spp., Persea sp. and Weinmannia pubescens (Renjifo et al. 2002, Echeverry-Galvis and Córdoba-Córdoba 2007), as well as areas with Palicourea, Asplundia, Besleria, and Allopectus (J. P. López-O per M. A. Echeverry-Galvis in litt. 2012). It forages mainly in dense understory in groups of no more than six individuals (M. A. Echeverry-Galvis in litt. 2012). Juveniles with adults have been seen in June in Cauca, August in Risaralda (Echeverry-Galvis and Cordoba-Cordoba 2007), and November and December in Pichincha (Lowen et al. 2000, Lowen and Benitez undated), where a nest with one egg has been found (also in November) (Greeney et al. 1998). The nest-site was in fairly disturbed forest (Greeney et al. 1998).

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):3.8
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Unplanned colonisation following the completion of roads, notably the Cali-Buenaventura and Pasto-Tumaco highways, and extensive logging concessions have been the primary causes of habitat loss (Salaman 1994, Wege and Long 1995, Salaman and Stiles 1996). Deforestation rates are accelerating within its range, primarily because of logging, human settlement, cattle-grazing, coca cultivation and gold mining (Dinerstein et al. 1995, Wege and Long 1995, Salaman and Stiles 1996). Montane forests are less threatened than those in the lowland Chocó region, but habitat loss is occurring, particularly below 2,000 m altitude (Dinerstein et al. 1995, Wege and Long 1995, Salaman and Stiles 1996). Munchique is affected by human settlement, and part of the cloud-forest was illegally burnt during exceptionally dry weather in 1997, to make the land grazeable, but this is apparently only rarely a threat (P. G. W. Salaman in litt. 1999).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
As well as Munchique and Cotacachi-Cayapas, it occurs in Farallones de Cali and Tatamá (M. A. Echeverry-Galvis in litt. 2012) National Parks, and Tambito and La Planada Nature Reserves, Colombia, and Mindo-Nambillo Protection Forest, Ecuador (Wege and Long 1995). Formerly listed as Vulnerable (Renjifo et al. 2002), it is now considered Least Concern at the national level in Colombia (Renjifo et al. 2014).

Conservation Actions Proposed
Survey poorly-known cloud-forests, notably in Farallones de Cali National Park (Wege and Long 1995, P. G. W. Salaman in litt. 1999). Study its ecological requirements, population density and conservation status (P. G. W. Salaman in litt. 1999, Lowen et al. 2000, M. S. Gregory in litt. 2001). Fund, support and enforce better protection of national parks, especially Munchique (P. G. W. Salaman in litt. 1999), and, in tandem, compensation of local people. Establish a monitoring program for the population in Risaralda, involving community based groups interested in bird conservation (Echeverry-Galvis & Cordoba-Cordoba 2007). Study basic life-history in Munchique and Tatama, including juvenile dispersal, diet, and breeding season (M. A. Echeverry-Galvis in litt. 2012).
