NT
Blue-whiskered Tanager Tangara johannae

Justification
This rare and local species is suspected to be declining moderately rapidly owing to the loss of forest habitats within the Chocó region. It is therefore listed as 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
Tangara johannae is rare to locally fairly common in the Pacific lowlands, from north Antioquia, Colombia, south through north-west Ecuador to Los Ríos (Ridgely and Tudor 1989, Ridgely and Greenfield 2001). It has been described as the least numerous Pacific lowland Tangara (Hilty and Brown 1986) but it is common in several areas in Nariño, Colombia (Salaman 1994, P. G. W. Salaman in litt. 1999).

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

Trend justification
Slow to moderate declines are likely to be occurring, owing to rapid and on-going habitat destruction and degradation throughout this species's range. However, precise data on the magnitude of these declines are lacking.

Ecology
This species occurs at the borders of wet forest and secondary woodland in coastal lowlands and foothills to 1,000 m (Hilty and Brown 1986), but very rare above 800 m (P. G. W. Salaman in litt. 1999).


Threats
The Chocó forests inhabited by this species are threatened by rapid and ongoing deforestation, largely as a result of intensive logging, human settlement, cattle-grazing, mining and coca and palm cultivation, with destruction most severe in its lowland habitats (Stattersfield et al. 1998).

Conservation Actions Underway
Conservation Actions Proposed
Repeat surveys of known sites in order to determine rates of population decline and range contraction. Conduct ecological studies to determine precise habitat requirements and tolerance of habitat degradation or fragmentation. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community led multiple use areas.
