Baya Weavers
The baya weaver (''Ploceus philippinus'') is a weaverbird found across the Indian Subcontinent and Southeast Asia. of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. They are widespread and common within their range but are prone to local, seasonal movements mainly in response to rain and food availability. Among the population variations, five subspecies are recognized. The nominate race ''philippinus'' is found through much of mainland India while ''burmanicus'' is found eastwards into Southeast Asia. The population in southwest India is darker above and referred to as subspecies ''travancoreensis''. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the baya w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hugh Whistler
Hugh Whistler (28 September 1889 – 7 July 1943), F.Z.S., M.B.O.U. was an English police officer and ornithologist who worked in India. He wrote one of the first field guides to Indian birds and documented the distributions of birds in notes in several journals apart from describing new subspecies. Life and career Hugh was the first son of Major Fuller Whistler of the Highland Light Infantry and Gwenllian Annie (née Robinson) and was born at Mablethorpe in 1889. Whistler was educated at Aldenham School. His younger brother Ralfe Allen Fuller Whistler (24 July 1895 - 28 April 1917) followed after his father and joined the Highland Light Infantry while Hugh went to serve with the Indian police mainly in the Punjab. He served in India from December 1909 to April 1926. He was initially posted at Phillaur but was later to serve across Punjab including districts such as Jhang that were considered unpopular. He was posted in other regions including Kangra, Lahul and Spiti. He began to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Munia
''Lonchura'' is a genus of the estrildid finch family, and includes munias (or minias) and mannikins. They are seedeating birds that are found in South Asia from India, Bangladesh, Sri Lanka east to Indonesia, Papua New Guinea, and the Philippines. The name mannikin is from Middle Dutch ''mannekijn'' 'little man' (also the source of the different bird name manakin). Some of the ''Lonchura'' species were formerly placed in ''Spermestes''. Others have been placed in a genus of their own, ''Euodice''. Characteristics They are small gregarious birds which feed mainly on seeds, usually in relatively open habitats, preferring to feed on the ground or on reeds of grasses. Several species have been noted to feed on algae such as ''Spirogyra''. The nest is a large domed grass structure into which four to ten white eggs are laid. Some species also build communal roosting nests for overnight rest. The species in this genus are similar in size and structure, with stubby bills, stocky bo ...

Acacia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photoperiodic
A circadian rhythm (), or circadian cycle, is a natural, internal process that regulates the sleep–wake cycle and repeats roughly every 24 hours. It can refer to any process that originates within an organism (i.e., endogenous) and responds to the environment ( entrained by the environment). These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in animals, plants, fungi and cyanobacteria. The term ''circadian'' comes from the Latin '' circa'', meaning "approximately", and ''dies'', meaning "day". Processes with 24-hour cycles are more generally called diurnal rhythms; diurnal rhythms should not be called circadian rhythms unless they can be confirmed as endogenous, and not environmental. Although circadian rhythms are endogenous, they are adjusted to the local environment by external cues called zeitgebers (German for "time givers"), which include light, temperature and redox cycles. In clinical settings, an abnormal circadian rhythm in hum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not wholl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pecking Order
In biology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social animal , social groups interact, creating a ranking system. A dominant higher-ranking individual is sometimes called an alpha, and the submissive lower-ranking individual a beta. Different types of interactions can result in dominance depending on the species, including ritualized displays of aggression or direct physical violence. In social living groups, members are likely to compete for access to limited resources and mating , mating opportunities. Rather than fighting each time they meet, relative rank is established between individuals of the same sex, with higher-ranking individuals often gaining more access to resources and mates. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. Definitions Dominance is an individu ...

House Sparrow
The house sparrow (''Passer domesticus'') is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus ''Passer'', the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, and deserts away from human development. It feeds mostly on the seeds of grains and weeds, but it is an opportunistic eater and commonly eats insects and many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
