Irena Tweeddalii
The Palawan fairy-bluebird (''Irena tweeddalii'') is a species of bird in the family Irenidae. It is native to Balabac Island, Palawan and the Calamian Islands in the Philippines. Its natural habitats are tropical moist lowland forest and it is declining due to habitat destruction and deforestation. Description and taxonomy EBird describes the bird as "Spectacular forest-dweller with blood-red eyes, endemic to Palawan and surrounding smaller islands. Gathers at fruiting and flowering trees. Frequently gives rising “wit!” notes, often in bursts of three, as well as incorporating them into short, melodious song." Exhibits sexual dimorphism in which male are midnight black and electric blue while the female is dark turquoise with dark wingtips. It was formerly conspecific with the Asian fairy-bluebird but split due to plummage differences with males have a lighter more electric blue versus the darker blue of the former. Females are duller and more turquiose in color. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Bowdler Sharpe
Richard Bowdler Sharpe (22 November 1847 – 25 December 1909) was an English people, English zoologist and ornithology, ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw (''Macronyx sharpei'') and Sharpe's starling (''Pholia sharpii''). Biography Richard was born in London, the first son of Thomas Bowdler Sharpe. His grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of ''Sharpe's London Magazine'', an illustrated periodical (weekly but monthly from 1847). His care from the age of six was under an aunt, Magdalen Wallace, widow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Fairy-bluebird
The Asian fairy-bluebird (''Irena puella'') is a medium-sized, arboreal passerine bird. This fairy-bluebird is found in forests across tropical southern Asia, Indochina and the Greater Sundas. Two or three eggs are laid in a small cup nest in a tree. It was described by British ornithologist John Latham (ornithologist), John Latham in 1790. The only other member of the genus and family is the Philippine fairy-bluebird, ''I. cyanogastra'', which replaces the Asian fairy-bluebird in most of the Philippines. Both species are considered as sacred to the Tagalog people as they are perceived as tigmamanukan omens. The adult Asian fairy bluebird is about . The male has glossy, iridescent blue upperparts, and black underparts and flight feathers. The female and first year male are entirely dull blue-green. The Asian fairy bluebird eats fruits, nectar and some insects. Its call is a liquid two note ''glue-it''. Description The Asian fairy bluebird measures in length. The iris is crimson ...

Endemic Birds Of The Philippines
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. Patterns of endemism The Wild Bird Club of the Philippines has a checklist of the birds of the Philippines which follows the IOC World Bird List. Of these 260 bird species endemic to the Philippines. Many of these are restricted to specific islands, particularly Luzon, Mindanao, and Palawan.''A Guide to the Birds of the Philippines'', Robert S. Kennedy et al., Oxford University Press, 2013. The number of endemic species recognized in the Philippines has increased in recent years, mainly due to " splits" of species and, to a much lesser extent, due to the discovery of previously unknown species. An example of splitting is the division of the erstwhile species Philippine hawk-owl (''Ninox scutulata'') into seven species, now called by the name of this-or-that boobook (Luzon boobook, Mindoro boobook, etc. see the list below). Another example is the split of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Palawan
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 furthe ...

Irena (bird)
The three fairy-bluebirds are small passerine bird species found in forests and plantations in tropical southern Asia and the Philippines. They are the sole members of the genus ''Irena'' and family (biology), family Irenidae, and are related to the ioras and leafbirds. These are bulbul-like birds of open forest or thorn scrub, but whereas that group tends to be drab in colouration, fairy-bluebirds are sexually dimorphic, with the males being dark blue in plumage, and the females duller green. These species eat fruit, especially figs, and possibly some insects. They lay two to three eggs in a tree nest. The call of the Asian fairy-bluebird is a liquid two note ''Glue-It''. As the names would suggest, the Asian fairy-bluebird (''I. puella'') occurs across southern Asia, the Philippine fairy-bluebird (''I. cyanogastra'') in that archipelago, and the Palawan fairy-bluebird (''I. tweeddalii'') on the island of Palawan (island), Palawan.

Puerto Princesa Subterranean River National Park
The Puerto Princesa Subterranean River National Park is a protected area in the Philippines. The park is located in the Saint Paul Mountain Range on the western coast of the island of Palawan, about north of the city of Puerto Princesa, and contains the Puerto Princesa Subterranean River (also known as the Puerto Princesa Underground River or just Underground River). It has been managed by the Puerto Princesa city government since 1992. It was listed as a UNESCO World Heritage Site in 1999, and voted as a New 7 Wonders of Nature in 2012. It also became a Ramsar Wetland Site in 2012. A major tourist destination, it is mostly accessed through road trips to the seaside village of Sabang from where one of the many Bangkas (Kayaks) take visitors to the park History In 2010, a group of environmentalists and geologists discovered that the underground river has a second floor, which means that there are small waterfalls inside the cave. They also found a cave dom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
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 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 partners ...

Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of reevaluating near-threatened taxa at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Those designated since 2001 that depend on conservation efforts to not become threatened are no longer separately considered conservation-dependent species. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria to assign conservation status, which included a separate category for conservation-dependent species ("Conservation Dependent", LR/cd). With this category system, Near Threatened and Con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primary Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without Disturbance (ecology), disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and Canopy (biology), canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debr ...

Naturalis Biodiversity Center - RMNH
Naturalis Biodiversity Center () is a national museum of natural history and a research center on biodiversity in Leiden, Netherlands. It was named the European Museum of the Year 2021. Although its current name and organization are relatively recent, the history of Naturalis can be traced back to the early 1800s. Its collection includes approximately 42 million specimens, making it one of the largest natural history collections in the world. History The beginnings of Naturalis go back to the creation of the Rijksmuseum van Natuurlijke Historie (abbreviated RMNH, National Museum of Natural History) by royal decree on August 9, 1820. In 1878, the geological and mineralogical collections of the museum were split off into a separate museum, remaining distinct until the merger of the Rijksmuseum van Natuurlijke Historie with the Rijksmuseum van Geologie en Mineralogie (abbreviated RGM) in 1984, to form the Nationaal Natuurhistorisch Museum (NNM) or National Museum of Natural ...

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] |
