Common name:

Order Passeriformes
Family Thraupidae

This South American species has a highly disjunct distribution, with three main areas of occurrence. One population is found in southern Venezuela, south-western Guyana and marginally into northern Brazil. A second population is found along the eastern slopes of the Andes, from Venezuela to central Bolivia. The third population is found in the Atlantic forests of southern and south-eastern Brazil, and also in southern Paraguay and marginally into northern Argentina.

These birds are 10-11 cm long and weigh about 13 g.

The blue-naped chlorophonia is found in moist tropical forests, rural gardens and plantations. They are present from sea level up to an altitude of 2.100 m.

They mainly eat berries and insect larvae, but also small leaves and nectar.

Blue-naped chlorophonias breed in December-July. The nest is a globular structure with side entrances, made of moss and rootlets, and placed in a road bank with overhanging vegetation or within a bromeliad, about 1 m above the ground. The female lays 2-3 whitish eggs with reddish-brown speckles, which she incubates alone for 17-20 days. The chicks are fed by both parents and fledge 20-21 days after hatching.

IUCN status - LC (Least Concern)
This species has a very large breeding range and is described as common. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
