This species has a very small and severely fragmented range and population. Remaining forest continues to be degraded and destroyed, and its range and population are therefore likely to be declining. It consequently qualifies as Endangered.

Geographic Range [top]

Range Description: Lipaugus weberi is confined to a small area of forest (c.800 km2) on the northern slope of the Central Andes in Colombia (Cuervo et al. 2001), where it is known from at least five locations (Renjifo et al. 2002), although this is likely to increase with the consideration of survey results published by Cuervo et al. (2008). The area lies between the Porce and Nechí river valleys, where it is presently known from four localities in the Municipality of Anorí (Cuervo et al. 2001). The species is locally common at the known localities in Anorí, especially between 1,600 and 1,750 m  (Cuervo et al. 2001, Renjifo et al. 2002). It is much less common near Amalfi, presumably because the forests in this area have been subjected to exploitation for a longer period of time (Renjifo et al. 2002).

Population [top]

Population: The population is estimated to number fewer than 2,500 individuals (del Hoyo et al. 2004), and so is placed in the band 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits primary pre-montane, wet forest between 1,500 and 1,820 m (Cuervo et al. 2001). It has been seen at forest borders and in secondary vegetation near mountain gorges, but not usually within secondary forest (Cuervo et al. 2001, Renjifo et al. 2002). Birds occur singly within the midstorey to lower canopy, and are sometimes observed in mixed-species flocks in the higher levels of the canopy (Renjifo et al. 2002). It feeds on small to medium-sized berries and, occasionally, large invertebrates (Cuervo et al. 2001).

Systems: Terrestrial

Threats [top]

Major Threat(s): The Central Andes have undergone almost complete ecological change - surviving forested areas are now highly fragmented and isolated. Pre-montane forest cover is estimated to be 3-4% of its original extent (Cuervo et al. 2001), and the species is presumed to have been extirpated from a large part of its range (Renjifo et al. 2002). Forest loss is driven by mining and agriculture, in particular coffee, plantain and cattle (Cuervo et al. 2001, Renjifo et al. 2002). Moreover, current high rates of colonization will increase deforestation in the area. High acidity and poor soil drainage reduce vegetation succession and accentuate problems of soil erosion (Renjifo et al. 2002). Afforestation with exotic species is an increasing problem in the area (Cuervo et al. 2001).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
However, La Reserva Natural La Forzosa, a fragment of pristine forest of 4.5 km2 between 1,500 and 1,820 m, has been designated following an ornithological exploration of the area (Cuervo et al. 2001, Renjifo et al. 2002). 1,310 acres of forest were purchased by the American Bird Conservancy to be managed by FundaciónProAves as the Arrierito Antioqueño Bird Reserve in 2006 (Anon 2006/2007).

Conservation Actions Proposed
Conduct detailed surveys to determine the extent of its distribution, population status, and genetic variation and exchange between the Amalfi and Anorí populations (Renjifo et al. 2002). Develop a management plan for the species. Pursue the protection of remaining pre-montane forest fragments in the region, particularly those persisting in the Riachón river valley in Amalfi (Renjifo et al. 2002). Control exploitation of palms and other forest resources. Encourage the local government to acquire land between 1,200 and 1,600 m for future protected areas. Encourage alternative technologies for the use of the land, and campaign to prevent the conversion of forests to pastures (Renjifo et al. 2002). There remains some large intact and potentially suitable subtropical forest areas in eastern and southeastern Antioquia. Conservation efforts in these areas may prove more practical and probably reveal healthy populations of this and other threatened species (Salaman in litt. 2003).
