Palm Crow
The palm crow (''Corvus palmarum'') is a relatively small corvid that occurs on the Caribbean island of Hispaniola ( Haiti and the Dominican Republic) and Cuba, where it was formerly very frequent, but is now reduced in population. Taxonomy The Cuban subspecies is slightly smaller, and is usually separated as a subspecies (''Corvus palmarum minutus''); the Hispaniolan subspecies' trinomial is ''Corvus palmarum palmarum'' (the nominate subspecies). Both subspecies are usually now given the respective common names of Hispaniolan palm crow and Cuban palm crow to distinguish them. Despite being sympatric with the white-necked crow (''Corvus leucognaphalus'') on Hispaniola, it appears to be more closely related to the fish crow (''C. ossifragus'') of the East Coast of the United States, as well as two smaller species, the Tamaulipas crow (''C. imparatus'') and Sinaloan crow (''C. sinaloae'') of Mexico, than the white-necked crow, which is more related to the Cuban crow (''Corvus ...

Birds Of Hispaniola
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Duke Paul Wilhelm Of Württemberg
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Enriquillo
Lake Enriquillo ( es, Lago Enriquillo) is a hypersaline lake in the Dominican Republic located in the southwestern region of the country. Its waters are shared between the provinces of Bahoruco and Independencia, the latter of which borders Haiti. Lake Enriquillo is the largest lake in both the Dominican Republic and Hispaniola, as well as the entire Caribbean. It is also the lowest point for an island country. Hydrology Lake Enriquillo covers an area of 145 mi2 (375 km2), and is the lowest point for an island country, falling below sea level. Its drainage basin includes 10 minor river systems. The rivers that rise in the Neiba Mountains to the north (lower center and lower right of the image) are perennial. Those rivers that rise in the Baoruco Mountains to the south are intermittent. Lake Enriquillo has no outlet. The lake's water level varies because of a combination of storm-driven precipitation events and the region's high evaporation rate. Salinity in the lake ...

Hispaniolan Pine Forests
The Hispaniolan pine forests are a subtropical coniferous forest ecoregion found on the Caribbean island of Hispaniola, which is shared by Haiti and the Dominican Republic. The ecoregion covers , or about 15% of the island. It lies at elevations greater than in the mountains of Hispaniola, extending from the Cordillera Central of the Dominican Republic and into the Massif du Nord of Haiti. It is surrounded at lower elevations by the Hispaniolan moist forests and Hispaniolan dry forests ecoregions, which cover the remainder of the island. Annual rainfall is . Flora The natural vegetation of the region consists primarily of stands of pino criollo (''Pinus occidentalis''). Pines are mixed with other conifers, including sabina ('' Juniperus gracilior'') and '' Podocarpus aristulatus'' (syn. ''P. buchii''). Below , pine forests are found on lateritic soils and are interspersed with areas of wet montane forest. Important broad-leaved species are '' Garrya fadyenii'' and '' Vac ...

Jamaican Crow
The Jamaican crow (''Corvus jamaicensis'') is a comparatively small corvid (35–38 cm in length). It shares several key morphological features with two other West Indian species, the Cuban crow (''Corvus nasicus'') and the white-necked crow (''Corvus leucognaphalus'') of Hispaniola, which are very closely related to it. Distribution and habitat As its name suggests, this species is found on the island of Jamaica, where it inhabits woodland mixed with cleared areas, and can be frequently found in larger gardens. Though primarily a bird of hill and mountain forest, it comes down to lower elevations during the dry season, where it is more likely to be seen. Description The overall appearance is sooty-grey, not at all glossy, like its relatives; though it does possess a similar dark grey patch of naked skin just behind the eye, and a smaller naked patch at the base of the bill. The bill itself is slate-grey and quite deep, tapering to a sharp point. The nasal bristles are rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuban Crow
The Cuban crow (''Corvus nasicus'') is one of four species of crow that occur on islands in the Caribbean. It is closely related to the white-necked crow (''C. leucognaphalus'') and Jamaican crow (''C. jamaicensis''), with which it shares similar features. The fourth Caribbean crow, the palm crow (''C. palmarum''), is a later arrival in evolutionary terms, and shows characteristics more akin to North American species, such as the fish crow (''C. ossifragus''), which it is probably closely related to. Distribution and habitat It can be found quite commonly over most of the large island of Cuba and on the nearby Isla de la Juventud (as well as the Turks and Caicos islands) in woodland and areas that have been cleared for agriculture. It is frequently found around farms and villages where it seems to have adapted quite well to living in relatively close contact with human settlements. Description A stocky, medium-sized ( in length) forest crow, the bill of this species is long and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
