Geospizopsis is a genus of seed-eating birds in the tanager family Thraupidae that are commonly known as sierra finches.
The two species now placed in Geospizopsis were formerly placed in the genus Phrygilus . A molecular phylogenetic study of the tanagers published in 2014 found that Phrygilus was polyphyletic. [2] In the subsequent rearrangement to create monophyletic genera, the genus Geospizopsis was resurrected. [3] [4] It had originally been introduced in 1856 by the French naturalist Charles Lucien Bonaparte with Passerculus geospizopsis Bonaparte, 1853 as the type species. [5] This taxon is now treated as a subspecies of the plumbeous sierra finch and has the trinomial name Geospizopsis unicolor geospizopsis. [4] The genus name combines Geospiza , a genus introduced by John Gould in 1837, with the Ancient Greek opsis meaning "appearance". [6]
The two species in the genus are: [4]
| Male | Female | Common Name | Scientific name | Distribution |
|---|---|---|---|---|
 |  | Plumbeous sierra finch | Geospizopsis unicolor | Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela. |
 | Ash-breasted sierra finch | Geospizopsis plebejus | Argentina, Bolivia, Chile, Ecuador, and Peru. | |
The typical honeycreepers form a genus Cyanerpes of small birds in the tanager family Thraupidae. They are found in the tropical New World from Mexico south to Brazil. They occur in the forest canopy, and, as the name implies, they are specialist nectar feeders with long curved bills.
Tachyphonus is a genus of birds in the tanager family Thraupidae.
Phrygilus is a genus of mainly Andean seed-eating tanagers commonly known as sierra finches. Phrygilos means finch in Ancient Greek. Traditionally classified in the bunting and American sparrow family Emberizidae, more recent studies have shown them to belong in the Thraupidae.
Idiopsar is a genus of Neotropical seed-eating birds in the tanager family Thraupidae.
Poospiza is a genus of finch-like birds in the tanager family Thraupidae that are found in both the South American lowlands and the Andes mountains. Generally they are arboreal feeders in light woodland and scrub. All have extensive grey to their plumage, and have—often bold—white or rufous markings.
The chestnut-headed tanager is a species of bird in the tanager family Thraupidae this is found in the Atlantic Forest of southeast Brazil, eastern Paraguay and far northeastern Argentina. It was formerly the only member of the genus Pyrrhocoma but is now placed in Thlypopsis.
The masked mountain tanager is a vulnerable species of bird in the tanager family Thraupidae. It is the only member of the genus Tephrophilus. This large and colourful tanager is endemic to elfin forest, woodland and shrub in the Andean highlands of southern Colombia, Ecuador and northern Peru. It is generally rare or uncommon, and is threatened by habitat loss.
Loxigilla is a genus of passerine birds in the tanager family Thraupidae. The two species are both endemic to the Lesser Antilles.
The mourning sierra finch is a species of South American bird in the tanager family Thraupidae. It is the only member of the genus Rhopospina.
The bay-chested warbling finch is a species of bird in the family Thraupidae. It is endemic to southeastern Brazil.
The blue-capped tanager is a species of bird in the tanager family Thraupidae. It was formerly placed in the genus Thraupis but is now the only species in the genus Sporathraupis.
