Rhodacanthis
''Rhodacanthis'' is an extinct genus of Hawaiian honeycreepers commonly known as koa finches. All four species were endemic to the Hawaiian Islands. Members of this genus were granivores, with bills adapted to the seeds and pods of legumes. The two species that became extinct in the 1890s, '' R. flaviceps'' and '' R. palmeri'', inhabited upper elevation mesic forests dominated by koa ''(Acacia koa'') on the island of Hawaii. Both were large birds; ''R. flaviceps'' measured , while ''R. palmeri'' was in length. The combination of a giant bill with brightly colored plumage (yellow for ''R. flaviceps'', orange for ''R. palmeri'') gave the males a very striking appearance. Koa seeds were the preferred food for the two species, but caterpillars were taken if necessary. The two prehistoric species, '' R. forfex'' and '' R. litotes'', were denizens of more lowland tropical dry forests and shrublands on Kauai, Maui, and Oahu. It is speculated that koaia (''Acacia koaia'') was an im ...

Primitive Koa Finch
The primitive koa finch (''Rhodacanthis litotes'') 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 Oahu, Oʻahu in Hawaii. Description An adult primitive koa finch was slender and had a total length of about . There was probably a small distinct difference between the sexes. Based on fossils, it is known that the adult primitive koa finch had a slightly curved, thick bill. The paper that named the species in 2005 also mentions, "the fossil record of ''Rhodacanthis'' may contain at least one additional Species complex, cryptic species. The difference in aperture of the nasal cavity in the Oahu vs. Maui fossils of ''R''. ''litotes'' suggests that those two populations might be recognized as distinct species if more fossils or genetic data were available for them." Distribution Primitive koa finch fossils have been found on Maui and Oahu, Oʻahu. Based on its disjunct dis ...

Hawaiian Honeycreeper
Hawaiian honeycreepers are a group of small, passerine birds endemic to Hawaii. They are closely related to the rosefinches in the genus ''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. Taxonomy Before the introduction of molecular phylogenetic techniques, the relationship of the Hawaiian honeycreepers to other bird species was controversial. The honeycreepers were sometimes categorized as a family Drepanididae,Clements, J. 2007. ''The Clements Checklist of the Birds of the World.'' 6th ed. other authorities considered them a subfamily, Drepanidinae, of Fringillidae, the finch fam ...

Greater Koa Finch
The greater koa finch (''Rhodacanthis palmeri'') was a species of finch in the family Fringillidae. It was found only in the Hawaiian Islands. It has been extinct since the late 19th century. Description The bird was about 7–8 in (18–20 cm) long when fully grown. It was the largest known honey-creeper, although its typical weight is unknown. The bird was sexually dimorphic; the male was brilliant scarlet-orange on head, neck, and breast, with lighter orange on its bottom, and olive brown with orange touches on back, wings, and tail; however, the female was brownish olive, and somewhat lighter below. It had a thick black bill which allowed it to break open seed pods that were found in the trees. In historical times, its range was largely confined to the Kona District of the island of Hawaii, although it was observed in the Kīlauea area in 1895. It was much more widespread prior to the arrival of humans in Hawaii, and related species lived on other islands. In Kona, it ...

Scissor-billed Koa Finch
The scissor-billed koa finch or scissor finch (''Rhodacanthis forfex'') 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 Kauaʻi in Hawaii. Distribution Scissor-billed koa finch fossils have been found on Maui and Kauai. Based on its disjunct distribution, the species might have occurred on all of the main islands (except the island of Hawaii), although more fossils are needed for confirmation. Diet The scissor-billed koa finch was a granivore, that, like the other members of its genus, had a bill adapted to eat the hard seeds and pods of legumes. Pollen and fossil evidence indicates that ''Ka palupalu o Kanaloa'' ('' Kanaloa kahoolawensis'') and ''koaia'' (''Acacia koaia'') were probably important food sources, and it may have eaten caterpillars and ''aalii'' (''Dodonaea viscosa'') berries. Extinction The koa finches seem to have been driven to extinction by habit ...

Lesser Koa Finch
The lesser koa finch (''Rhodacanthis flaviceps'') is an extinct species of Hawaiian honeycreeper. Description The only specimens of the lesser koa finch ever caught were a family group with members of different ages and genders, ideal for study.George C. Munro. (1944) The males were apparently golden-yellow with olive green on the breast and belly. The females were almost indistinguishable from the species' larger relative, the greater koa finch The greater koa finch (''Rhodacanthis palmeri'') was a species of finch in the family Fringillidae. It was found only in the Hawaiian Islands. It has been extinct since the late 19th century. Description The bird was about 7–8 in (18–20 ..., other than the fact that the former were slightly darker in color. The juveniles were somewhat mottled on the belly, similar to the females. As its name suggests, the species as a whole was smaller than the other scientifically described koa finches, measuring on average only five inche ...

Acacia Koaia
''Acacia koaia'', known as ''koaia'' or ''koaie'' in Hawaiian, is a species of acacia that is endemic to Hawaii. It is closely related to ''koa'' (''Acacia koa''), and is sometimes considered to be the same species. Description ''Acacia koaia'' is usually distinguished by growing as a short (rarely more than ), broad, gnarled tree; having the seeds longitudinally arranged in the pod; shorter, straighter phyllodes; and much denser wood. A population on the northern coast of Kauai may be intermediate, but the relationships have not been worked out. ''Koaia'' wood is claimed to be very different from that of ''koa'', and this may be the best character to separate them. Distribution ''Acacia koaia'', ''Koaia'', is highly adapted to dry habitats, and is capable of forming dense forests in areas with very little rainfall. It was formerly found widely in dry forests on all of the main islands. Associated plants include ''uluhe'' (''Dicranopteris linearis''), ''hala'' (''Pandanu ...

Kauai
Kauai, () anglicized as Kauai ( ), is geologically the second-oldest of the main Hawaiian Islands (after Niʻihau). With an area of 562.3 square miles (1,456.4 km2), it is the fourth-largest of these islands and the 21st largest island in the United States. Nicknamed the Garden Isle, Kauai lies 73 miles (117 km) across the Kauai Channel, northwest of Oahu. This island is the site of Waimea Canyon State Park and the Na Pali Coast State Park. The United States Census Bureau defines Kauai as census tracts 401 through 409 of Kauai County, Hawaii, which comprises all of the county except the islands of Kaʻula, Lehua and Niihau. The 2020 United States census population of the island was 73,298. The most populous town is Kapaa. Etymology and language Hawaiian narrative locates the name's origin in the legend of Hawaiiloa, the Polynesian navigator credited with discovery of the Hawaiian Islands. The story relates how he named the island of Kauai after a favorite son; ...

Oahu
Oahu () (Hawaiian language, Hawaiian: ''Oʻahu'' ()), also known as "The Gathering place#Island of Oʻahu as The Gathering Place, Gathering Place", is the third-largest of the Hawaiian Islands. It is home to roughly one million people—over two-thirds of the population of the U.S. state of Hawaii. The island of O’ahu and the Northwestern Hawaiian Islands constitute the City and County of Honolulu, Hawaii, City and County of Honolulu. The state capital, Honolulu, is on Oʻahu's southeast coast.

Berry
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples are strawberries, raspberries, blueberries, blackberries, red currants, white currants and blackcurrants. In Britain, soft fruit is a horticultural term for such fruits. In common usage, the term "berry" differs from the scientific or botanical definition of a fruit produced from the ovary of a single flower in which the outer layer of the ovary wall develops into an edible fleshy portion (pericarp). The botanical definition includes many fruits that are not commonly known or referred to as berries, such as grapes, tomatoes, cucumbers, eggplants, bananas, and chili peppers. Fruits commonly considered berries but excluded by the botanical definition include strawberries, raspberries, and blackberries, which are aggregate fruits and mulberries, which are mu ...
