Justification:
This species has a small range, and is known from a small number of locations. Its known population is suspected to be small, fragmented into very small subpopulations, and declining as a result of continuing habitat loss. Consequently, it is listed as Vulnerable.

Geographic Range [top]

Range Description:	Chlorochrysa nitidissima occurs in the west and north-central Andes of Colombia (in Antioquia, Caldas, Risaralda, Quindío, Valle del Cauca and Cauca). There are records from only two sites in the central Andes since 1951: Ucumarí Regional Park, Risaralda, in the early 1990s (Wege and Long 1995), and the northernmost locality near Anorí, Antioquia, in 1999 (A. Cuervo in litt. 1999). The great majority of modern records in the west Andes are from accessible sites in Valle del Cauca. It was formerly common, but is now infrequently recorded, although it remains fairly common locally, even in remnant forest fragments.

Population [top]

Population:	Extrapolating recorded densities across the species's range (assuming 10% of its Extent of Occurrence is likely to be occupied) gives a preliminary population estimate of 21,970 individuals. As this is a rough estimate, it is best placed in the band 20,000-49,999 individuals. A more accurate population estimate is desirable.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits humid, mossy, montane forest and borders in the subtropical zone at 1,300-2,200 m, exceptionally as low as 1,140 m in the central Andes, and 900 m in the West Andes. In adjacent areas, it also occurs regularly in mature secondary forest and clearings with a few large trees left standing. The diet comprises insects, mainly taken when foraging with mixed-species flocks, and fruit.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Deforestation has been severe in many parts of its range, notably Valle del Cauca, Cerro Tatamá, along the Buenaventura-Cali and Buenaventura-Buga roads, and around Medellín (Wege and Long 1995, Salaman and Stiles 1996). However, large blocks of primary forest remain, e.g. in Farallones de Cali and Los Nevados national parks, and on the Caramanta Massif (Wege and Long 1995, Stiles 1998). The rapid expansion of the road network is opening up more remote parts of the species's range to logging, mining and human settlement (Salaman and Stiles 1996). Immigration will inevitably lead to deforestation (Stiles 1998), through small-scale agriculture and subsistence activities.

Conservation Actions:	Conservation Actions Underway It has been recently recorded in the Ucumarí section of Los Nevados National Park, Yotoco Forest Reserve, Farallones de Cali National Park, Tambito Nature Reserve and Munchique National Park (Wege and Long 1995, P. G. W. Salaman in litt. 1999). The northernmost site is within a proposed regional park (A. Cuervo in litt. 1999). Education and awareness activities within the western Andes have included local schools participating in a Bird Month Celebration and publication of a conservation magazine (Fierro-Calderón et al. 2009). Conservation Actions Proposed Survey poorly-known areas of habitat, e.g. in Farallones de Cali National Park (L. Dávalos in litt. 1999). Enforce conservation measures in protected areas, specifically in providing non-damaging alternatives to settlers in Munchique National Park and the Tambito region (L. Dávalos in litt. 1999, P. G. W. Salaman in litt. 1999, T. Donegan in litt. 2012). Research its ecological requirements and population size (Renjifo et al. 2002). Use recent information to produce a regional management plan for the western Andes (Fierro-Calderón et al. 2009).
