Geospiza fuliginosa

Photo by Douglas Bolt (Mango Verde)

Common name:
small ground-finch (en); tentilhão-da-terra-pequeno (pt); géospize fuligineux (fr); pinzón terrestre pequeno (es); kleingrundfink (de)

Taxonomy:
Order Passeriformes
Family  Thraupidae

Range:
These birds are endemic to the Galapagos islands, being found in the islands of the archipelago except Genovesa, Wolf and Darwin.

Size:
Small ground-finches are 11 cm long and weigh 14 g.

Habitat:
They are mostly found in arid lowland zones, dominated by cacti, deciduous scrubs and dwarf trees, but also occur in forests at higher altitudes, up to an altitude of 1.700 m.

Diet:
These birds forage on the ground or in low vegetation, eating seeds, buds, flowers and leaves, and to a lesser extent also arthropods and the the fruits of Opuntia cacti. They are also known to glean parasites from the skin of iguanas and tortoises.

Breeding:
The small ground-finch breed opportunistically, with egg-laying being most profuse when rainfall is high and food abundant. They are typically monogamous and maintain small territories where they build a small dome-shaped nest on a scrub or cactus. There the female lays 3 eggs which are incubated for 12 days. The chicks are fed mostly insects and fledge 2 weeks after hatching.

Conservation:
IUCN status - LC (Least Concern)
Although this species has a relatively small breeding range, it is described as common and widespread. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

blue-necked tanager (en); saíra-de-cabeça-azul (pt); calliste à cou bleu (fr); tangara cabeciazul (es); azurkopftangare (de)

Taxonomy:
Order Passeriforme
Family Thraupidae

Range:
This South American species occurs in two separate populations. One found along the lower slopes of the Andes, from Venezuela and Colombia south, on the west side of the Andes, to western Ecuador, and, on the east side of the Andes, south to Bolivia. The other population occupies the lowlands of southern Amazone forest, in central Brazil and marginally into eastern Bolivia.

Size:
These birds are 12-13 cm long and weigh 14-19 g.

Habitat:
The blue-necked tanager is found in tropical scrublands and dry savannas, as well as in the canopy of primary evergreen rainforests and also in plantations and second growths. They are present from sea level up to an altitude of 2.400 m.

Diet:
They are omnivorous, eating insects, flower buds and fruits. Among others, they are known to eat Miconia berries and Cecropia catkins and fruits.

Breeding:
Blue-necked tanagers can probably breed all year round. They nest in a tree hollow, lined with leaves and moss, where the female lays 2 white eggs with brown spots. The female incubates the eggs alone for 13-15 days, while the male brings her food. The chicks are fed by both parents and fledge 15-20 days after hatching, becoming independent about 3 weeks later.

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

Oreomanes fraseri

Photo by Sam Woods (Surf Birds)

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.
