Antillean Siskin
The Antillean siskin (''Spinus dominicensis'') is a species of finch in the family Fringillidae, and the only species of the genus ''Spinus (genus), Spinus'' found in the Caribbean. Distribution and habitat It is endemic to Hispaniola (in both Haiti and the Dominican Republic). Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest. Evolution This seems to be the most ancient extant species of the North American ''Spinus (genus), Spinus'' evolutive radiation, being the first to diverge from the lineage which eventually gave rise to the Pine siskin, pine, Eurasian siskin, Eurasian, and Black-capped siskin, black-capped siskins.

Henry Bryant (naturalist)
Henry Bryant (May 12, 1820 – February 2, 1867) was an American physician and natural history, naturalist. Early life Bryant was born in Boston, and graduated from Harvard University in 1840, and then followed this from a degree at Harvard Medical School in 1843. Following this, he went to Paris to study medicine, but his health broke down while researching at a Paris hospital. In order to restore his health, he joined the French army in Algeria as a surgeon. In October 1847, Bryant returned to Boston to work with Dr. Henry Jacob Bigelow as a surgeon, but after a few months his health broke down again. After being forced to abandon medicine because of ill health, Bryant turned to natural history, especially ornithology, which was a childhood passion. Bryant visited nearby Cohasset, Massachusetts for one of his first collecting trips, but he seriously injured his stomach from a fall while landing his boat. After his recovery, he decided to push himself further in an attempt t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine Siskin
The pine siskin (''Spinus pinus'') is a North American bird in the finch family. It is a migratory bird with an extremely sporadic winter range. Taxonomy The pine siskin was formally described in 1810 by the American ornithologist Alexander Wilson under the binomial name ''Fringilla pinus''. The specific epithet ''pinus'' is the Latin word for a "pine-tree". The type locality is Philadelphia, Pennsylvania. The pine siskin is now placed in the genus '' Spinus'' that was introduced in 1816 by the German naturalist Carl Ludwig Koch in 1816. Three subspecies are recognised: * ''S. p. pinus'' ( Wilson, A, 1810) – Alaska, Canada and west, northeast USA * ''S. p. macropterus'' ( Bonaparte, 1850) – northwest and central Mexico * ''S. p. perplexus'' Van Rossem, 1938 – south Mexico to Guatemala Description These birds are fairly small, being around the same size as the widespread American goldfinch. In both sexes, total length can range from , with a wingspan of and weigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1868
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. Birds ...

Endemic Birds Of The Caribbean
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] |

Black-capped Siskin
The black-capped siskin (''Spinus atriceps'') is a species of finch in the family Fringillidae. It is found in Mexico and Guatemala. Its natural habitats are subtropical or tropical moist montane forest and heavily degraded former forest. Phylogeny It has been obtained by Antonio Arnaiz-Villena et al. Identification ''Spinus atriceps'' has been defined as a finch with a gray wash and a black cap. However, other green morphs have been also identified with ''Spinus atriceps'', but apparently they are pine siskin The pine siskin (''Spinus pinus'') is a North American bird in the finch family.

Eurasian Siskin
The Eurasian siskin (''Spinus spinus'') is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include ''black-headed goldfinch'', ''barley bird'' and ''aberdevine''. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers. It can be distinguished from other similar finches by the colour of the plumage. The upper parts are greyish green and the under parts grey-streaked white. Its wings are black with a conspicuous yellow wing bar, and the tail is black with yellow sides. The male has a mainly yellow face and breast, with a neat black cap. Female and young birds have a greyish green head and no cap. It is a trusting, sociable and active bird. The song of this bird is a pleasant mix of twitters and trills. For these reasons it is often raised in captivit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.''
