Barbuda Warbler
The Barbuda warbler (''Setophaga subita'') is a species of bird in the family Parulidae. It is Endemism, endemic to the island of Barbuda in Antigua and Barbuda. Its natural habitat is tropical dry shrubland near wetland areas. It is threatened by habitat loss. It once was considered a subspecies of the Adelaide's warbler. In September 2017, the warbler's habitat was massively damaged by Hurricane Irma. Despite this, the species was found to have survived the storm and its aftermath, and later surveys have indicated that the species was not significantly affected by the hurricane. However, it is still threatened by unplanned Housing estate, housing development, garbage dumping, and poor Land use, land-use practices. Description The Barbuda warbler is 12–13.5 cm long and weighs 5-8 grams. It is yellow below with gray upperparts, and a gray eyering.

Joseph Harvey Riley
Joseph Harvey Riley (September 19, 1873 – December 17, 1941) was an American ornithologist. Born in Falls Church, Virginia, Riley was employed at the Smithsonian Institution from 1896 until his death, becoming Associate Curator of the Division of Birds in 1932. A species of Bahamian iguana, '' Cyclura rileyi'', is named in his honor.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''.

Adelaide's Warbler
Adelaide's warbler (''Setophaga adelaidae'') is a bird endemic to the archipelago of Puerto Rico belonging to the genus ''Setophaga'' of the family Parulidae. The species is named after Adelaide Swift, daughter of Robert Swift, the person who captured the first specimen. Description The ''S. adelaidae'' complex was originally considered a single species, with three populations occurring in Barbuda, Puerto Rico and St. Lucia. Each of these populations were regarded as a subspecies, ''S.a. subita'', ''S.a. adelaidae'' and ''S.a. delicata'' respectively. These subspecies were later elevated to species rank as the Barbuda warbler (''Setophaga subita''), the St. Lucia warbler (''Setophaga delicata'') and Adelaide's warbler. In 2011, the American Ornithologists' Union reclassified the Parulidae, which resulted in ''D. adelaidae'' being transferred to genus ''Setophaga.'' Adelaide's warbler has gray upperparts with yellow underparts. The species has a yellow line above the eye and a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1904
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 Antigua And Barbuda
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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setophaga
''Setophaga'' is a genus of birds of the New World warbler family Parulidae. It contains at least 33 species. The males in breeding plumage are often highly colorful. The ''Setophaga'' warblers are an example of adaptive radiation with the various species using different feeding techniques and often feeding in different parts of the same tree. Most ''Setophaga'' species are long-range migrants, wintering in or near the New World tropics and seasonally migrating to breed in North America. In contrast, two ''Setophaga'' species, the palm warbler and yellow-rumped warbler, have winter ranges that extend along the Atlantic coast of North America as far north as Nova Scotia. Taxonomy The genus ''Setophaga'' was introduced by the English naturalist William Swainson in 1827. The type species was subsequently designated by Swainson in the same year as the American redstart ''Setophaga ruticilla''. The genus name is from Ancient Greek ''ses'', "moth", and ', "eating".

Land Use
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10,000 years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems" and as "the total of arrangements, activities, and inputs that people undertake in a certain land type." Land use is one of the most important drivers of global environmental change. History Human tribes since prehistory have segregated land into territories to control the use of land. Today, the total arable land is 10.7% of the land surface, with 1.3% being permanent cropland. Regulation Land use practices vary considerably across the world. The United Nations' Food and Agriculture Organization Water Development Division explains that "Land use concerns the produ ...

Housing Estate
A housing estate (or sometimes housing complex or housing development) is a group of homes and other buildings built together as a single development. The exact form may vary from country to country. Popular throughout the United States and the United Kingdom, they are often areas of high-density, low-impact residences of single-family detached homes and often allow for separate ownership of each housing unit, for example through subdivision. In major Asian cities, such as Hong Kong, Kuala Lumpur, Shanghai, Shenzhen, Singapore, Seoul, Taipei, and Tokyo, an estate may range from detached houses to high-density tower blocks with or without commercial facilities; in Europe and America, these may take the form of town housing, high-rise housing projects, or the older-style rows of terraced houses associated with the Industrial Revolution, detached or semi-detached houses with small plots of land around them forming gardens, and are frequently without commercial facilities an ...

Hurricane Irma
Hurricane Irma was an extremely powerful Cape Verde hurricane that caused widespread destruction across its path in September 2017. Irma was the first Category 5 hurricane to strike the Leeward Islands on record, followed by Maria two weeks later. At the time, it was considered as the most powerful hurricane on record in the open Atlantic region, outside of the Caribbean Sea and Gulf of Mexico until it was surpassed by Hurricane Dorian two years later. It was also the third strongest Atlantic hurricane at landfall ever recorded, just behind the 1935 Labor Day Hurricane and Dorian. The ninth named storm, fourth hurricane, second major hurricane, and first Category 5 hurricane of the 2017 season, Irma caused widespread and catastrophic damage throughout its long lifetime, particularly in the northeastern Caribbean and the Florida Keys. It was also the most intense hurricane to strike the continental United States since Katrina in 2005, the first major hurrican ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high and su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
