Western Chat-tanager
The western chat-tanager (''Calyptophilus tertius'') is a Vulnerable species of passerine bird belonging to the family Calyptophilidae. It is endemic to the island of Hispaniola which is shared by the Dominican Republic and Haiti. Taxonomy and systematics The western chat-tanager shares its genus with the eastern chat-tanager (''C. frugivorus''), and was previously treated as a subspecies of it. There is a high degree of divergence between the two in mitochondrial DNA and intron sequences. Speciation is likely to have occurred on two ancient islands, which later fused to form present-day Hispaniola. The genus was long included in the family Thraupidae, the "true" tanagers, but it was moved in 2017. The western chat-tanager is monotypic. Description The western chat-tanager is long and weighs about . It has a long bill and tail, so it somewhat resembles a mockingbird's shape. The sexes have the same plumage. Adults have a dark olive-brown head, with a blackish crown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Wetmore
Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. Early life and education The son of a Country Physician, Frank Alexander Wetmore was born in North Freedom, Wisconsin. Developing an interest in birds at an early age, he made his first field journal entry (a pelican seen while on vacation in 1894) at the age of eight. By 1900, Wetmore published his first paper "My Experience with a Red-headed Woodpecker," in the magazine Bird-Lore. To further his education Wetmore enrolled at the University of Kansas in 1905. During his studies there he did a stint as an assistant in the University Museum, under the direction of Charles D. Bunker. Alexander Wetmore later received his BA from the University of Kansas in 1912; finally receiving his MS in 1916 & PhD in 1920 from George Washington University. Wetmore began federal service in 1910, working for the Biological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mockingbird
Mockingbirds are a group of New World passerine birds from the family Mimidae. They are best known for the habit of some species mimicking the songs of other birds and the sounds of insects and amphibians, often loudly and in rapid succession. There are about 17 species in two genera, although three species of mockingbird from the Galapagos Islands were formerly separated into a third genus, ''Nesomimus''. The mockingbirds do not appear to form a monophyletic lineage, as ''Mimus'' and ''Melanotis'' are not each other's closest relatives; instead, ''Melanotis'' appears to be more closely related to the catbirds, while the closest living relatives of ''Mimus'' appear to be thrashers, such as the sage thrasher.Hunt, Jeffrey S.; Bermingham, Eldredge; & Ricklefs, Robert E.

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] |
Endemic Birds Of Hispaniola
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] |

Calyptophilus
''Calyptophilus'' is a genus of bird formerly placed in the family Thraupidae. The group was found to be distinct enough to be placed in its own family, Calyptophilidae. Established by Charles Barney Cory in 1884, it contains the following species: * Western chat-tanager The western chat-tanager (''Calyptophilus tertius'') is a Vulnerable species of passerine bird belonging to the family Calyptophilidae. It is endemic to the island of Hispaniola which is shared by the Dominican Republic and Haiti. Taxono ..., ''Calyptophilus tertius'' * Eastern chat-tanager, ''Calyptophilus frugivorus'' These two species were formerly considered conspecific under ''C. frugivorus'' (with the common name of chat tanager). The name ''Calyptophilus'' comes from the Greek words ''kaluptēs'', meaning "hider" (derived from ''kaluptō'', meaning "to cover") and ''philos'', meaning "loving" (derived from ''phileō'', meaning "to love").

Brown Rat
The brown rat (''Rattus norvegicus''), also known as the common rat, street rat, sewer rat, wharf rat, Hanover rat, Norway rat, Norwegian rat and Parisian rat, is a widespread species of common rat. One of the largest muroids, it is a brown or grey rodent with a head and body length of up to long, and a tail slightly shorter than that. It weighs between . Thought to have originated in northern China and neighbouring areas, this rodent has now spread to all continents except Antarctica, and is the dominant rat in Europe and much of North America. With rare exceptions, the brown rat lives wherever humans live, particularly in urban areas. Selective breeding of the brown rat has produced the fancy rat (rats kept as pets), as well as the laboratory rat (rats used as model organisms in biological research). Both fancy rats and laboratory rats are of the domesticated subspecies ''Rattus norvegicus domestica''. Studies of wild rats in New York City have shown that populations livi ...

Black Rat
The black rat (''Rattus rattus''), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus ''Rattus'', in the subfamily Murinae. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke. Taxonomy ''Mus rattus'' was the scientific name proposed by Carl Linnaeus in 1758 for the black rat. Three subspecies were once recognized, but today are considered invalid and are now known to be actually color morphs: *''Rattus rattus rattus'' – roof rat *''Rattus rattus alexandrinus'' – Alexandrine rat *''Rattus rattus frugivorus'' – fruit rat Characteristics A typical adult black rat is long, n ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadleaf Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Sierra De Bahoruco
The Bahoruco Mountain Range—Sierra de Bahoruco (or Sierra de Bahoruco) is a mountain range located in the far southwestern region of the Dominican Republic. It is within Pedernales, Independencia, Barahona, and Bahoruco Provinces. A large part of the area is protected within the Sierra de Bahoruco National Park (''Parque Nacional Sierra de Bahoruco''), also a Biosphere reserve. Its name is mentioned for the first time by Bartolomé de las Casas in his "Brief History of the Indies", who takes it from the phonetic sound used by the Taino Indians to describe that region. It is rich in deposits of salt and gypsum, and also has a lagoon in the southern part (Oviedo lagoon) and between this mountain range and the Neiba mountain range is Lake Enriquillo, the largest in the Antilles. Geology The mountain range is a massif of volcanic origin from the Cretaceous period (from 145 to 66 million years ago) and later covered by a layer of calcareous sediment of marine origin, this means t ...
