Viridian Dacnis Dacnis viguieri

Justification
This species occurs within a moderately small range, is known from relatively few locations, and is generally considered rare. It is likely to be in decline owing to ongoing habitat loss and degradation, and is therefore considered Near Threatened.

Taxonomic source(s)
SACC. 2006. A classification of the bird species of South America. Available at: #http://www.museum.lsu.edu/~Remsen/SACCBaseline.html#.

Distribution and population
Dacnis viguieri occurs in north-west Colombia (north Chocó, north-west Antioquia, south-west Córdoba) and east Panama (east Darién) (Hilty and Brown 1986, Ridgely and Gywnne 1989, Ridgely and Tudor 1989). Within this small range it is generally rare. The species is known from 44 specimens in Colombia, with all but four collected at Jurado, Chocó, on the Pacific coast at the base of Serranía de los Saltos (Fundación ProAves 2011). A recent record from Panama comes from Cana, at the foothills of Cerro Pirre, thus the species probably also occurs on the Colombian side of Cerro Tacarcuna (Fundación ProAves 2011).

Population justification
The global population size has not been quantified, but this species is described as 'rare'.

Trend justification
Data on trends are lacking, but slow to moderate declines are likely to be occurring, owing to habitat loss within parts of the range.

Ecology
Although primarily a humid forest species, D. viguieri uses edge habitat and has been recorded in scrub (Hilty and Brown 1986, Isler and Isler 1987). It has been recorded most often in foothills up to 700 m, where it may be more numerous than in the flat coastal lowlands (Hilty and Brown 1986, Ridgely and Tudor 1989).

Threats
In the Urabá lowlands and the Sinú valley, most habitat has been converted to banana plantations and cattle ranches (P. G. W. Salaman in litt. 1999, Fundación ProAves 2011), and more recently palm oil plantations (Fundación ProAves in press). This agricultural expansion has cleared the lowlands almost entirely and is encroaching on the foothills of the Western Andes and Serranía de Darien. In Panama, deforestation is on-going near El Real and is likely to be taking place in the Jaque valley (G. R. Angehr in litt. 2011). Some extensive, largely intact forests remain in Panama and Chocó, but these would be threatened by the completion of the Pan-American highway through Daríen (Wege 1996).

Conservation Actions Underway
No targeted action is known. Conservation Actions Proposed
Survey all known and historical sites to determine current range and estimate rates of contraction and population decline. Conduct ecological studies to identify habitat associations and assess levels of tolerance of habitat disturbance. Protect areas of suitable habitat and safeguard against clearance.
