Green-naped Tanager Tangara fucosa

Justification
This species occurs within a very small range, and although its habitats are currently secure, and hence population trends are assumed to be stable, it is likely to be moderately susceptible to future human pressures. It is therefore classified as Near Threatened.

Distribution and population
Tangara fucosa is fairly common in the region of east Darién (Cerro Pirre, Cerro Mali, Cerro Tacarcuna and the Serranía de Junguruda), Panama (Isler and Isler 1987, Ridgely and Gywnne 1989, G. R. Angehr in litt. 2000), with a further sight record of one bird near the ridge of Cerro Tacarcuna, north Chocó, Colombia (Pearman 1993).

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction.

Ecology
Most records of this species are from montane evergreen and elfin forests and edge habitats above 1,350 m, although it is known to occur down to 550 m (Isler and Isler 1987, Ridgely and Gywnne 1989), with a pair observed building a nest at c.940 m in the Río Sambú drainage of Darién province (Christian 2001).

Threats
This species has a very small range and is therefore inherently at risk from any habitat loss or degradation, which is already occurring as a result of gold mining operations below this species's altitudinal range (Stattersfield et al. 1998). Completion of the Pan-American Highway link through Darién could be highly detrimental to this species (Wege 1996).

Conservation Actions Underway
Conservation Actions Proposed
Monitor trends in habitat cover within the species's range to identify potential threats. Campaign against the completion of the planned Darién Pan-American Highway link.
