Green-throated Euphonia Euphonia chalybea

Justification
This species is listed as Near Threatened as it is suspected to be declining moderately rapidly as a result of habitat loss within its small range.

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
Euphonia chalybea is fairly common, but local, in the Atlantic forests of south-east Brazil (Rio de Janeiro south to Rio Grande do Sul), east Paraguay (recently in Canindeyú, Alto Paraná, Caazapá and Itapuá, with historical records from Amambay), and north-east Argentina (Corrientes and Misiones) (Ridgely and Tudor 1989, Hayes 1995, Lowen et al. 1996, Clay et al. 1998, J. Mazar Barnett 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 on-going habitat loss and fragmentation.

Ecology
This species occurs sparsely in lowland forest, forest edge and overgrown plantations to 500 m, and has been recorded feeding (perhaps predominantly) on cactus fruits (probably epiphytic) (Isler and Isler 1987, Sick 1993) and mistletoes (J. Mazar Barnett in litt. 1999).

Threats
This species has presumably declined substantially with the extensive loss of Atlantic forest to agriculture and mining, with current key threats from urbanisation, industrialisation, agricultural expansion, colonisation and associated road-building (Dinerstein et al. 1995, Fearnside 1996).

Conservation Actions Underway
Conservation Actions Proposed
Repeat surveys of known sites in order to monitor population trends and rates of range contraction. Conduct further ecological studies to identify habitat requirements. Protect areas of suitable habitat.
