The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers.
Maui Nui is a modern geologists' name given to a prehistoric Hawaiian island and the corresponding modern biogeographic region. Maui Nui is composed of four modern islands: Maui, Molokaʻi, Lānaʻi, and Kahoʻolawe. Administratively, the four modern islands comprise Maui County. Long after the breakup of Maui Nui, the four modern islands retained plant and animal life similar to each other. Thus, Maui Nui is not only a prehistoric island but also a modern biogeographic region.
The Laysan finch is a species of Hawaiian honeycreeper, that is endemic to the Northwestern Hawaiian Islands. It is one of four remaining finch-billed Hawaiian honeycreepers and is closely related to the smaller Nihoa finch. The Laysan finch is named for Laysan, the island to which it was endemic on its discovery. It was subsequently introduced to a few other atolls, and its historical range included some of the main islands.
The Nihoa finch is one of the two endemic bird species of the tiny Hawaiian island Nihoa, the other being the Nihoa millerbird. When it was classified in 1917, scientists thought that it would be the last endemic species named. This was later found untrue. The island's population is 1000–3000 birds. The Nihoa finch was added to the Endangered Species List by the U.S. Fish and Wildlife Service on March 11, 1967. An attempt to protect the species against extinction was made by starting a colony on French Frigate Shoals, another leeward island. This would ensure its continued existence in case the Nihoa population was wiped out. This attempt, however, failed. Nihoa is part of a group of islands that make up the Hawaiian Islands National Wildlife Refuge which provides protected land for the Nihoa finch to roam on.
The Laysan millerbird was a subspecies of the millerbird, similar in appearance to the remaining subspecies, the Nihoa millerbird. Its dorsal side was brown, and its belly was grayish. Its name derives from its favorite food, several species of moths of the genus Agrotis commonly referred to as "millers".
The cardueline finches are a subfamily, Carduelinae, one of three subfamilies of the finch family Fringillidae, the others being the Fringillinae and the Euphoniinae. The Hawaiian honeycreepers are now included in this subfamily. Except for the Hawaiian honeycreepers which underwent adaptive radiation in Hawaii and have evolved a broad range of diets, cardueline finches are specialised seed eaters, and unlike most passerine birds, they feed their young mostly on seeds, which are regurgitated. Besides this, they differ from the other finches in some minor details of their skull. They are adept at opening seeds and clinging to stems, unlike other granivorous birds, such as sparrows and buntings, which feed mostly on fallen seeds. Some members of this subfamily are further specialised to feed on a particular type of seed, such as cones in the case of crossbills. Carduelines forage in flocks throughout the year, rather than keeping territories, and males defend their females rather than a territory or nest.
Ciridops is an extinct genus of Hawaiian honeycreeper species that occurred in prehistoric and historic times on the Hawaiian islands of Hawaii, Molokai, Kauai and Oahu. This genus was created in 1892 by Alfred Newton in an article published by the journal Nature on the basis of the ʻula-ʻai-hawane, which was named Fringilla anna by Sanford B. Dole in 1879.
The lesser koa finch is an extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It was endemic to the island of Hawaiʻi.
Rhodacanthis, commonly known as the koa finches, is an extinct genus of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. All four species were endemic to Hawaii.
The highland finch is an extinct member of the Fringillidae and a Hawaiian honeycreeper which is known only from a few bones found in caves. It is the only member of the genus Orthiospiza. It was endemic to the high-elevation areas of Mount Haleakalā on the Hawaiian island of Maui. It has been speculated that they were pushed to extinction because of habitat loss. It is known only from fossil remains and likely became extinct before the first Europeans arrived in 1778.
The Kauai finch is an extinct bird in the genus Telespiza of the family Fringillidae. It was endemic to the Hawaiian islands of Kauai and Oahu. It is only known from fossil remains and likely became extinct before the first Europeans visited Hawaii in 1778.
The Maui Nui finch is an extinct member of the genus Telespiza in the family Fringillidae. It was endemic to the Hawaiian islands of Molokai and Maui. It is only known from fossil remains and likely became extinct before the first Europeans visited Hawaii in 1778.
The primitive koa finch is an extinct species of Hawaiian honeycreeper in the subfamily Carduelinae of the family Fringillidae. It is known from fossils on the islands of Maui and Oʻahu in Hawaii.
The King Kong grosbeak or giant grosbeak is a prehistoric species of Hawaiian honeycreeper, that was endemic to Hawaiʻi. It had the largest beak of the three Chloridops species known to have existed. The King Kong grosbeak was described from fossils found at Barber's Point and Ulupau Head on the island of Oʻahu. It was 11 inches (28 cm) long, making it one of the largest Hawaiian honeycreepers. The osteology of the mandible strongly suggests that C. regiskongi was a sister-taxon of Rhodacanthis.
Xestospiza is an extinct genus of containing two species of Hawaiian honeycreeper with cone-shaped bills that were described on the basis of bones. They were possibly insectivores. It consists of the following:
Hawaiian honeycreepers are a group of small birds endemic to Hawaiʻi. They are members of the finch family Fringillidae, closely related to the rosefinches (Carpodacus), but many species have evolved features unlike those present in any other finch. Their great morphological diversity is the result of adaptive radiation in an insular environment. Many have been driven to extinction since the first humans arrived in Hawaii, with extinctions increasing over the last 2 centuries following European discovery of the islands, with habitat destruction and especially invasive species being the main causes.
Apteribis is an extinct genus of flightless birds in the ibis subfamily that was endemic to the Hawaiian Islands in the Pacific Ocean.
The Northwestern Hawaii scrub is a tropical and subtropical grasslands, savannas, and shrublands ecoregion on the Northwestern Hawaiian Islands in the Pacific Ocean.
