Taxonomy:
Order Passeriformes
Family Thraupidae

Range:
These birds are found in northern South America and Central America, from northern Brazil and Peru to southern Mexico.

Size:
The wing-barred seedeater is 11-12 m long and weighs 12-13 g.

Habitat:
They are mostly found in open areas, such as grasslands, scrublands, pastures and agricultural areas, but sometimes also in tropical forests and within urban areas.

Diet:
The wing-barred seedeater feeds mainly on grass seeds, but also takes other seeds, berries and some insects. They forage in small flocks, often mixed with other species.

Breeding:
These birds nest in a flimsy cup built by the female with coarse plant material and lined with a few finer fibres. The nest is placed in low in a tree, up to 6 m above the ground. The female lays 2-3 pale grey eggs with brown speckles, which she incubates alone for 12-14 days. The chicks fledge 2 weeks after hatching. Each pair can raise 2-4 broods per year.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population estimated at 0,5-5 million individuals. The population is suspected to be declining owing to trapping pressure, but it is not considered threatened at present.

Common name:
giant conebill (en); figuinha-gigante (pt); conirostre géant (fr); pájaro de los queñuales(es); riesenspitzschnabel (de)

Taxonomy:
Order Passeriformes
Family Thraupidae

Range:
This South American species is found in the central and northern Andes, in southern Colombia, Ecuador, Peru and Bolivia.

Size:
These birds are 15 cm long and weigh 22-27 g.

Habitat:
The Giant Conebill is restricted to Polylepis woodlands, a high-elevation forest type that occurs above cloud level, at altitudes of 2.700-4.850 m.

Diet:
They are mainly insectivorous, eating caterpillars, beetles, small moth and aphids, but are known to probe the flowers of epiphytic mistletoes for nectar.

Breeding:
Giant conebills breed in October-December. The nest is an open cup made of twigs and sticks of Polylepis interwoven with soft plant material, and lined with moss, thin strips of Polylepis bark, feathers and sheep wool. The nest is placed within dense foliage, 2-3 m above the ground. The female lays 1-3 white eggs with brown specks, which are incubated by both parents. There is no information regarding the incubation period, but the chicks are known to be fed by both parents and fledge 14-16 days after hatching.

Conservation:
IUCN status - NT (Near-Threatened)
This species has a relatively large but patchy breeding range. The global population size has not been quantified, but the giant conebill is described as uncommon and patchily distributed. The population is suspected to be undergoing a moderate decline owing to the destruction and fragmentation of Polylepis woodlands as a result of uncontrolled use of fire, firewood collection, intense grazing by cattle, unsound agricultural techniques and afforestation with exotic tree species.
