The campo troupial is endemic to northeastern Brazil, It typically inhabits dry scrubland and deciduous woodland, The diet consists of insects and other small invertebrates, fruits and nectar.

Its natural habitats are: humid subtropical or tropical lowland forests and highly degraded secondary forests. It is not seen in open areas or outside dense vegetation.

The tropical screech owl is a nocturnal owl. It hibernates in the dense foliage of trees or bushes. It likes to use the protection of a thorn bush or sit in dense epiphyte growth close to tree trunks. The male's song can often also be heard during the day. The food spectrum mainly comprises insects. These include moths, cicadas, grasshoppers and beetles as well as spiders and occasionally small vertebrates.

The yellow-fronted woodpecker is native to eastern South America. The species has a mixed diet consisting mainly of berries and fruits, but including seeds, insects and their larvae.

The birds are usually found in humid forest and at edges, from sea level to 1200 m, and looking for food in lower growth or the midstory.

​Social flycatchers breed in plantations, pasture with some trees, and open woodland. It is a common and wide-ranging species.They like to perch openly in trees, several meters above ground. From such perches they will sally out for considerable distances to catch insects in flight, to which purpose they utilize a range of aerobatic maneuvers. They have been observed to forage peacefully alongside common marmosets.

During the day, the Pauraque rests on the ground or sits camouflaged lengthwise on a low branch in nightjar manner. At night, it hunts for beetles, moths and fireflies in low patrol flights or from a perch. The Pauraque spends more time on the ground than other nightjars. It often rests on the road at night.

The plain parakeet is found in eastern Brazil. It inhabits the Mata Atlantica where it occurs in secondary forests, cultivated land with groves of trees, plantations, and urban parks. It is common in cities  like Rio de Janeiro and São Paulo. The plain parakeet feeds mainly on seeds, fruit, flowers, and nectar from a very wide variety of plants and trees.

Cobalt-rumped parrotlets are mainly found in lowlands. They occur in dry and riparian woodlands, cerrado, caatinga, palm groves, semi-arid scrublands, savanna and pastures. The cobalt-rumped parrotlet is not known to be affected by deforestation or the pet trade, unlike many of its close relatives in the genus Forpus.

The species inhabits a wide variety of semi-open landscapes including edges and clearings in wet and sand-ridge forests, secondary forest, cerrado, gallery forests, in savanna, and plantations of fruit trees like papaya. The black-necked aracari forages in the forest's upper level and the canopy, It mostly feeds on fruit and is important as a disperser of fruit tree seeds.

The cardinal occurs in a wide range of dry to semi-humid open to semi-open habitats in north-eastern Brazil, especially the Caatinga region.

It inhabits forests as well as open, tree-covered terrain. The species is adaptable in its habitat requirements. It inhabits both semi-humid and semi-arid regions. It is found in deciduous forests and gallery forests, otherwise in open grassland, often on the edge of human settlements, and in some places has also opened up urban habitats. Its range has expanded, particularly in Brazil, where this species benefits from the conversion of forests into agricultural land

The Golden-fronted piculet inhabits a variety of forested landscapes, including rainforests, cloud forests and secondary forests. It can also be found in bamboo forests, mangroves, open forests and on the edges of savannahs.

Capped herons mostly inhabit marshes or mangroves with extensive shallow water areas, but they can also be found along river courses or shallow lakes with adjacent wet meadows. Although they are mostly found in fresh water, brackish water biotopes are also colonized. Sometimes they can also be found in rice fields.

The swallow occurs in both humid and arid climate zones. It prefers open terrain and forest clearings, often close to inhabited areas. Here they can be found from sea level to 4000 meters above sea level. On the tepuis of Venezuela, they can be seen in colonies near road cuts and rocky outcrops.

A frugivorous bird, it is easily found in its natural biome wherever there is food enough available, tending to behave aggressively towards other species of birds when disputing for food. Its habitats include shrubby areas that are not forested, including coastal scrub, forest clearing and edge, swamps, gardens, and city parks.

The saffron finch is common in open and semi-open areas in lowlands. It is a gregarious bird that forms small flocks and searches for seeds on the ground.

While essentially a bird of humid forests, it is also common in orchards and parks, where it moves through the canopy.

The birds feed primarily on fruit, and to a lesser extent on arthropods. Fruits are usually eaten upside down. Food is often sought in the treetops. The red-bellied tanagers live in pairs or small groups, sometimes in company with other tanager species.

These birds actively search for food in the vegetation. They feed mainly on insects such as butterfly larvae, beetles and bugs, but also on spiders and snails. Southern wrens rarely participate in mixed-species feeding flocks.

The red-bellied thrush feeds mainly on insects, larvae, earthworms and ripe fruit, including man-grown fruit such as papayas, oranges and avocados. The fruits of various palm species are also on their menu. Red-bellied thrushes live close to humans and prefer open areas such as forest edges, parks and gardens with plenty of water.

This species is found in marshy savannahs, reedbeds and the edges of mangrove swamps. White-headed marsh tyrants wait on an exposed low perch in marsh vegetation or a branch near water, occasionally sallying out to feed on insects.

 Its natural habitats are subtropical or tropical mangrove forests, subtropical or tropical moist shrubland, and heavily degraded former forest.

The sulphur-masked tyrant is a noisy, sociable bird that also defends its territory against larger birds. The omnivore feeds on insects, rodents, lizards and frogs, as well as fruit. It also catches fish by diving and is able to catch small bats in flight.

The spectacled owl is primarily a bird of tropical rainforests and is mainly found in areas with dense, old forest. However, it can also move into secondary habitats such as forest edges, particularly when hunting. Occasionally they also occur in dry forests, wooded savannah plains, plantations and semi-open areas with trees.

The species is mainly found in savannahs, wet meadows and lagoon areas, but has now also spread to agricultural and inhabited areas and in some cases even invades urban areas.
