Andaman Treepie
The Andaman treepie (''Dendrocitta bayleii'') is a species of bird in the family Corvidae. First described by Robert Christopher Tytler in 1863, it is endemic to the Andaman Islands of India, where its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease .... The scientific name commemorates the Anglo-Indian statesman Edward Clive Bayley.

Robert Christopher Tytler
Robert Christopher Tytler (25 September 1818 – 10 September 1872) was a British soldier, naturalist and photographer. His second wife Harriet C. Tytler is well known for her work in photographing and documenting the monuments of Delhi and for her notes at the time of the 1857 revolt in India. Mount Harriet in the Andamans was named after her. A species of bird, Tytler's leaf warbler, is named after him. Biography His father, Robert Tytler (18 Nov 1787 – 17 March 1838, Gwalior), served as a surgeon in the Bengal Native Infantry and his mother, Elizabeth Schneeburg (1782–1852) was the daughter of a German count. Tytler joined the Bengal army in 1834 after going to Leith High School in Edinburgh, and arrived in India in 1835 to join his father's regiment, the 34th Bengal Native Infantry. He saw many years of active military service in India, and in 1842 he was promoted to baggage-master. He later became interpreter and quartermaster and took part in the actions of the First ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvidae
Corvidae is a Cosmopolitan distribution, cosmopolitan Family (biology), family of Songbird, oscine passerine birds that contains the crows, ravens, Rook (bird), rooks, magpies, jackdaws, jays, treepies, choughs, and Nutcracker (bird), nutcrackers. In Colloquialism, colloquial English, they are known as the crow family or corvids. Currently, 139 species are included in this family. The genus ''Corvus'' containing 50 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable Animal cognition, intelligence for animals of their size, and are among the most Bird intelligence, intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (Eurasian magpies) and Tool use by animals, tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other mammals.

Endemic
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Andaman Islands
The Andaman Islands () are an archipelago, made up of 200 islands, in the northeastern Indian Ocean about southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar. The Andaman Islands are home to the Andamanese peoples, Andamanese, a group of indigenous people made up of a number of tribes, including the Jarawas (Andaman Islands), Jarawa and Sentinelese. While some of the islands can be visited with permits, entry to others, including North Sentinel Island, is banned by law. The Sentinelese are generally hostile to visitors and have had Uncontacted peoples, little contact with any other people. The Indian government and coast guard protect th ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Habitat
In ecology, habitat refers to the array of resources, 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 Biophysical environment, 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 Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an ecosystem characterized by a dense ecological community, community of 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 (biology), 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 (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Clive Bayley
Sir Edward Clive Bayley (17 October 1821 – 30 April 1884), was an Anglo-Indian civil servant, statesman and archaeologist. Early life Bayley was the only son of Edward Clive Bayley, of Hope Hall, Eccles, Lancashire, and Margaret Fenton. He was born at St. Petersburg in October 1821, and educated at the East India Company College. Career Bayley entered the Indian civil service in 1842, and served at Allahabad, Meerut, Bulandshahr, and Rohtak. On the annexation of the Punjab he was appointed deputy-commissioner at Gujarat in April 1849, and in November under-secretary to the government of India in the foreign department, under Sir Henry Elliot. Two years later he became deputy-commissioner of the Kangra district, but in 1854 was compelled by poor health to take leave. In England Bayley studied law, and he was called to the bar in 1857; he returned to India on the outbreak of the mutiny later that year. In September 1857 he was ordered to Allahabad, where he served as an un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrocitta
''Dendrocitta'' is a genus of long-tailed passerine birds in the crow and jay family, Corvidae. They are resident in tropical South Asia, South and Southeast Asia. The generic name is derived from the Greek language, Greek words ''dendron'', meaning "tree," and ''kitta'', meaning "magpie". The species are plumaged in black, grey and rufous. Typically, the face and flight feathers are black, and the back is rufous. They are highly arboreal and rarely come to the ground to feed. They are, in taxonomic order: References * Madge and Burn, ''Crows and Jays'' External linksTreepie videos on the Internet Bird Collection {{Taxonbar, from=Q811555 Dendrocitta, Bird genera Taxa named by John Gould ...
