Camarhynchus
''Camarhynchus'' is a genus of birds in the tanager family Thraupidae. All species of ''Camarhynchus'' are endemic to the Galápagos Islands, and together with related genera, they are collectively known as Darwin's finches. Formerly classified in the bunting and American sparrow family Emberizidae, more recent molecular genetic studies have shown it to belong in the tanager family. Taxonomy and species list The genus ''Camarhynchus'' was introduced in 1837 by English ornithologist John Gould, with the large tree finch as the type species. The name combines the Ancient Greek ''kamara'' meaning "arch" or "vault" with ''rhunkhos'' meaning "bill". The members of the genus form part of a group collectively known as Darwin's finches. Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, molecular phylogenetic studies have shown that Darwin's finches are members of the subfamily Coerebinae within the tanager family Thraupidae.

Darwin's Finches
Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the South American '' Tiaris obscurus''. They were first collected when the second voyage of the ''Beagle'' visited the Galápagos Islands, with Charles Darwin on board as a gentleman naturalist. Apart from the Cocos finch, which is from Cocos Island, the others are found only on the Galápagos Islands. The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book ''Darwin's Finches''. Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy ...

Woodpecker Finch
The woodpecker finch (''Camarhynchus pallidus'') is a monomorphic species of bird in the Darwin's finch group of the tanager family, Thraupidae endemic to the Galapagos Islands. The diet of a woodpecker finch revolves mostly around invertebrates, but also encompasses a variety of seeds. Woodpecker finches, like many other species of birds, form breeding pairs and care for young until they have fledged. The most distinctive characteristic of woodpecker finches is their ability to use tools for foraging. This behaviour indicates that they have highly specialized cognitive abilities. Woodpecker finches have also shown the ability to learn new behaviours regarding tool use via social learning. Not all populations of woodpecker finches use tools equally as often, as this is influenced by the environment in which they live. Description Woodpecker finches range in weight from 23g to 29g and are about 15 cm long. Although their tongues are quite short, they have a relatively lon ...

Medium Tree Finch
The medium tree finch (''Camarhynchus pauper'') is a critically endangered species of bird in the Darwin's finch group of the tanager family Thraupidae. It is endemic to the Galápagos Islands where it is only found on Floreana Island. Its name is derived from the fact that the bird's beak is intermediate in size between that of the small tree finch and the large tree finch. Because it has a very small range on a single island, and because of the introduction of a parasitic fly which kills the nestlings, the International Union for Conservation of Nature has rated the medium tree finch as " critically endangered". Distribution This species is only found on Floreana Island at elevations above 250 meters in moist highland forest habitats. Prime breeding habitat is dominated by '' Scalesia pedunculata'' trees. Ecology The diurnal Galapagos short-eared owl is its only remaining natural predator. Medium tree finches generally lay two to three eggs. Eggs are incubated for appro ...

Thraupidae
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. ''Euphonia'' and ''Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily (Euphoniinae). Likewise, the genera ''Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), '' Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.

Mangrove Finch
The mangrove finch (''Camarhynchus heliobates'') is a species of bird in the Darwin's finch group of the tanager family Thraupidae. It is endemic to the Galápagos Islands. It was found on the islands of Fernandina and Isabela, but recent surveys have failed to record the species on Fernandina. It has been classified as critically endangered by BirdLife International, with an estimated population of 20–40 mature individuals in 2021, located in two large mangroves on Isabela. A study has shown that the two small populations remaining on Isabela Island have begun undergoing speciation and that one or both populations will eventually become extinct due to a lack of interbreeding. Habitat As its name suggests, the mangrove finch lives in the mangroves of the Galápagos Islands. The mangrove finch feeds upon the various insects, larvae, spiders, and vegetable matter found in the mangroves. It closely resembles the far commoner woodpecker finch, but is not known to use tools.

Camarhynchus Parvulus
The small tree finch (''Camarhynchus parvulus'') is a species of bird in the Darwin's finch group of the tanager family Thraupidae. It has a grasping beak with curved culmens. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It m .... During the non-breeding season it is known to form large groups with small ground-finches. It is an endemic species to the Galapagos islands and its conservation status has been listed as “Least Concern”. However, bird counts which have been conducted since 1997 have shown a continuous decline in small tree-finch populations in the ''Scalesia'' and agricultural zones of Santa Cruz, where the small tree-finch is most abundant.
