The double-collared seedeater (Sporophila caerulescens) is a species of bird in the family Thraupidae.
It is found in Argentina, Bolivia, Brazil, Paraguay, Peru, and Uruguay, as well as the southern border of Colombia on the Amazon River. Its natural habitats are subtropical or tropical moist shrubland, pastureland, and heavily degraded former forest.
It is a dimorphic species, with the male having a gray head and back, a black-collared throat, paired with a black band just below, across the upper whitish breast. It has gray legs, a medium length tail, and the stout bill for seed-eating. The female is less colorful.
The species ranges from central Argentina east of the Andes cordillera northwards through Bolivia and Paraguay, and northeastwards into south-central Brazil, and southeast coastal Brazil; the species retreats into Amazonia during the austral winter. The double-collared seedeater is only found in the southern Amazon Basin, limited by the Amazon River as its northern limit.
In the west Amazon Basin it is found in eastern regions of Peru, the Ucayali River areas, and mostly the eastern bank of the north-flowing river. In the southeast Basin, it ranges from the Cerrado into the upstream two-thirds of the north-flowing Araguaia- Tocantins River drainage system.
The saffron finch is a tanager from South America that is common in open and semi-open areas in lowlands outside the Amazon Basin. They have a wide distribution in Colombia, northern Venezuela, western Ecuador, western Peru, eastern and southern Brazil, Bolivia, Paraguay, Uruguay, northern Argentina, and Trinidad and Tobago. It has also been introduced to Hawaii, Panama, Puerto Rico and elsewhere. Although commonly regarded as a canary, it is not related to the Atlantic canary. Formerly, it was placed in the Emberizidae but it is close to the seedeaters.
The plush-crested jay is a jay of the family Corvidae. It is found in central-southern South America: in southwestern Brazil, Bolivia, Paraguay, Uruguay, and northeastern Argentina, including southern regions of the Amazon Basin river systems bordering the Pantanal.
The white-eared puffbird is a species of bird in the Bucconidae family, the puffbirds. It is found in Argentina, Bolivia, Brazil, Paraguay and Peru, where it inhabits tropical and subtropical dry forests, subtropical and tropical moist forests, gallery forests, tropical savanna, and heavily degraded former forest.

The fiery-capped manakin is a species of bird in the family Pipridae, the manakins. It is one of the five species in the genus Machaeropterus. It is named for its bright yellow head feathers.
The chestnut-crowned becard is a species of bird in the family Tityridae. It has traditionally been placed in Cotingidae or Tyrannidae, but evidence strongly suggest it is better placed in Tityridae, where it is now placed by the South American Classification Committee.
The southern mouse-colored tyrannulet is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Paraguay, Peru, and possibly French Guiana and Suriname.
The rusty-collared seedeater is a species of bird in the family Thraupidae, formerly placed in the related Emberizidae.
The rufous-rumped seedeater, also known as the grey-and-chestnut seedeater, is a species of bird in the family Thraupidae. It breeds in southern Paraguay, Argentina, and Uruguay. It migrates northward to Bolivia, the Pantanal and central Brazil. Its natural habitats are dry savanna, subtropical or tropical seasonally wet or flooded lowland grassland, and pastureland. It is threatened by habitat loss.
The white-bellied seedeater is a species of bird in the family Thraupidae. It is found mainly in Bolivia, Paraguay and eastern Brazil, with smaller numbers in Suriname, southeastern Peru and northern Argentina. Its natural habitats are subtropical or tropical moist shrubland, swamps, and heavily degraded former forest.
The lined seedeater is a species of bird in the family Thraupidae.
The marsh seedeater is a species of bird in the family Thraupidae. It is sexually dichromic, with the males sporting a bright white throat, grey crown and chestnut belly, and the females resembling other brown female seedeaters.

The blue-crowned trogon is a species of bird in the family Trogonidae, the quetzals and trogons. It is found in Brazil, Argentina, Bolivia, Colombia, Ecuador, Paraguay, and Peru. As with all trogons, this species is sexually dimorphic. The male has a blue head with an orange orbital ring, a red belly with a narrow white breastband and a green back. The female differs in having a grey head, a grey back and a broken white eye-ring.
The wing-barred seedeater is a passerine bird from coastal regions of north-eastern South America in north-eastern Venezuela, Tobago, the Guianas, Amapá and north-eastern Pará, Brazil, and along the Amazon River upstream to around Manaus. Formerly, it included the mainly Central American Sporophila corvina and the west Amazonian S. murallae as subspecies, in which case the combined species had the common name Variable Seedeater. Following the split, this common name is now restricted to S. corvina.
The Memorandum of Understanding (MoU) on the Conservation of Southern South American Migratory Grassland Bird Species and Their Habitats is a Multilateral Environmental Memorandum of Understanding concluded under the auspices of the Convention on Migratory Species of Wild Animals (CMS), also known as the Bonn Convention and became effective on 26 August 2007. Under the “umbrella” of the CMS, the governments of Argentina, Bolivia, Paraguay and Uruguay agreed to work together towards better conservation of migratory species of grassland birds of Southern South America. The MoU covers five range States, all of which have signed.
