Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches 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 distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''

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 ...

ʻAkiapolaʻau
The akiapōlāau (''Hemignathus wilsoni''), pronounced ''ah-kee-ah-POH-LAH-OW'', is a species of Hawaiian honeycreeper that is endemic to the island of Hawaii. Its natural habitats are dry and montane moist forests, and the only bird species on the island to occupy the woodpecker niche. The bird is in length, and has an unusually curved beak-(a specialist species). The akiapolaau is a pudgy bird which has a whitish bottom and tail, black legs, yellow chest, orangish head, black face mask and bill and gray black wings. The male's song is either a loud, short ''pit-er-ieu'' or a rapid ''warba-warba''. Its various calls include an upslurred whistle, a short ''cheedle-ee'' warble, and a short ''sweet''. Due to the recent disappearance of the Kauai nukupuu in the 1900s and the Maui nukupu u in the 1990s, leading to fears that they may be extinct, the akiapōlāau may be the last of its genus. It is the only member of the subgenus ''Heterorhynchus'', which has a woodpecker-like fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carduelinae
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.Newton, 1973, p. 31 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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kauaʻi Nukupuʻu
The Kauai nukupuu (''Hemignathus hanapepe'') was a species of nukupuʻu once found throughout parts of the Hawaiian island of Kauai. It was an insect eater that picked out its tiny prey from tree bark. The males were yellowish with brown wings, while the females were grayish brown with a yellow throat streak. Conservation The species was abundant until the 19th century, when the loss of its lowland forests to slash and burn farming methods damaged its habitat. By 1889, this bird was very rare, though it could still be found in small flocks in the higher forests. The last confirmed sighting was in 1899; if the species survived after this time, it likely became confined to the Alakaʻi Wilderness Preserve. From 1984-1998, it was recorded several times in this area, but later analysis of these sightings indicates that almost all these observations were likely of Kauaʻi ʻamakihi (''Chlorodrepanis stejnegeri''). It was also feared that the winds from Hurricane Iniki Hurrican ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oʻahu Nukupuʻu
The Oahu nukupuu (''Hemignathus lucidus'') was a species of nukupuu which was similar to its cousins from the Islands of Kauai and Maui. It is yellowish greyish with a long hooked beak to find insects. This bird is now extinct due to human activity. Description The males were mostly yellow across the belly and on the head. From the bend of the wing, the feathers were primarily olive green. Its lores and legs were black. The females and the young had similar coloration with the exception that the yellow was a dull yellow. They had a long decurved beak approximately one and a half inch in length, the upper bill being twice as long as the lower. Using their upper bill to pluck insects found underneath tree bark, the Oahu nukupuu fed on insects on flowering trees such as the koa (''Acacia koa'') and ohia (''Metrosideros polymorpha''). These trees attract a large amount of insects due to their nectar-filled flowers. The Oahu nukupuu fed on koa in high elevation forests and ...

Insectivore
A robber fly eating a hoverfly An insectivore is a carnivorous animal or plant that eats insects. An alternative term is entomophage, which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians. When they evolved 400 million years ago, the first amphibians were piscivores, with numerous sharp conical teeth, much like a modern crocodile. The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related. Most of the Insectivora taxa have been reclassified; those that have not yet been reclassified and found to be truly related to each other remain in the order Eulipotyphla. Although individually small, insects exist in enormous numbers. Insects make u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bi ...

Endemic Fauna Of Hawaii
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maui Nukupuʻu
The Maui nukupuu (''Hemignathus affinis'') is a species of nukupu‘u Hawaiian honeycreeper that was endemic to the island of Maui in the Hawaiian Islands. The small, five-inch-long bird lived only in eastern Maui, where it was dependent on high-elevation mesic and wet forests of ōhia lehua (''Metrosideros polymorpha'') and koa (''Acacia koa''). These two species of trees attract insects, causing the Maui nukupuu to have a higher chance of finding a meal near these trees. It was last sighted in the late 1990's, and is most likely extinct. Description The females were colored green on the nape and head, and yellow on its face, neck, belly, and bottom. The females were completely olive green and were quieter than their male counterparts. Juveniles were gray and green. The bird's inch-long bill was used to peck for insects in the tree's bark. Population This species existed in the Hanawi Area Reserve from 3,000 feet to 4,500 feet above sea level. It formerly survived at lowe ...
