Rufous-headed Tailorbird
The rufous-headed tailorbird (''Phyllergates heterolaemus'') is a species of bird in the family Cettiidae. It is found only in the Philippines on the island of Mindanao. Its natural habitats are in tropical moist montane forest. Description and taxonomy EBird describes the bird as "A small, long-billed, long-tailed bird of montane forest and scrub on Mindanao, with an olive back, wings, and tail, a yellow belly, a rufous head, and a pale buff throat and chest. Often cocks its tail. Juvenile has an olive rather than rufous head. Similar in shape and habits to other tailorbirds on Mindanao, but occurs at higher elevations, and has a yellow belly and rufous head. Song consists of very short, well spaced, varied phrases of fairly long, high-pitched piping notes." It was formerly conspecific with the Mountain tailorbird but differs greatly in plumage. Behaviour and ecology Diet is presusmed to be tiny invertebrates. Typically seen in pairs or small family parties deep within ta ...

Edgar Alexander Mearns
Edgar Alexander Mearns (September 11, 1856 – November 1, 1916) was an American surgeon, ornithologist and field naturalist. He was a founder of the American Ornithologists' Union. Life Mearns was born in Highland Falls, New York, to Alexander and Nancy Reliance Mearns (née Clarswell). His grandfather Alexander was of Scottish origin and moved to Highland Falls in 1815. Edgar Mearns was educated at the Donald Highland Institute (Highland Falls). He attended the Columbia College of Physicians and Surgeons, graduating in 1881. In 1881, he married Ella Wittich of Circleville, Ohio. The couple had one son and one daughter. Their son was born in 1886 and died in 1912. Mearns became a doctor in the U.S. Army.

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Birds Described In 1905
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 furth ...

Phyllergates
The species of tailorbirds listed below are small birds of the genus '' Phyllergates ''. They were previously placed in the Old World warbler family Sylviidae. However, recent research suggests they more likely belong in the Cettiidae. They occur in the Old World tropics, principally in Asia. These warblers are usually brightly colored, with green or grey upperparts and yellow white or grey underparts. They often have chestnut on the head. Tailorbirds have short rounded wings, short tails, strong legs and long curved bills. The tail is typically held upright, like a wren. They are typically found in open woodland, scrub and gardens. Tailorbirds get their name from the way their nest is constructed. The edges of a large leaf are pierced and sewn together with plant fibre or spider's web to make a cradle in which the actual grass nest is built.

Slash-and-burn
Slash-and-burn agriculture is a form of shifting cultivation that involves the cutting and burning of plants in a forest or woodland to create a Field (agriculture), field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the Biomass (ecology), biomass is burned, resulting in a nutrient-rich layer of ash which makes the Soil fertility, soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Conversion
Land development is the alteration of landscape in any number of ways, such as: * Changing landforms from a natural or semi-natural state for a purpose such as agriculture or housing * Subdividing real estate into lots, typically for the purpose of building homes * Real estate development or changing its purpose, for example by converting an unused factory complex into a condominium History Land development has a history dating to Neolithic times around 8,000 BC. From the dawn of civilization, the process of land development has elaborated the progress of improvements on a piece of land based on codes and regulations, particularly housing complexes. Economic aspects In an economic context, land development is also sometimes advertised as land improvement or land amelioration. It refers to investment making land more usable by humans. For accounting purposes, it refers to any variety of projects that increase the value of the process. Most are depreciable, but some land improv ...

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] |
IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Cettiidae
Cettiidae is a newly validated family of small insectivorous songbirds (" warblers"), formerly placed in the Old World warbler "wastebin" assemblage. It contains the typical bush warblers ('' Cettia'') and their relatives. As a common name, cettiid warblers is usually used. Some taxonomic authorities include this entire family, along with the related genera ''Erythrocercus'' and '' Scotocerca'', in an enlarged family Scotocercidae. Its members occur mainly in Asia, ranging into Oceania and Europe. The pseudo-tailorbirds, tesias and stubtails, as well as '' Tickellia'' and '' Abroscopus'' warblers, are mostly found in the forests of south and southeastern Asia, with one species of stubtail reaching as far north as Japan and Siberia. Only one species, Neumann's warbler (''Hemitesia neumanni''), occurs in Africa. The range of the genus '' Cettia'' extends west to Western Europe, while that of '' Horornis'' extends well into the Pacific, as far as Fiji and Palau. Most of the spec ...

EBird
eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science. eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others. History and purpose Launched in 2002 by the Cornell Lab of Ornithology at Cornell University and the National Audubon Society, eBird gathers basic data on bird abundance and distribution at a variety of spatial and temporal scales. It was mainly inspired by the , created by Jacques Larivée ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
