Palawan Swiftlet
The Ameline swiftlet (''Aerodramus amelis''), also known as the grey swiftlet is a small bird in the swift family Apodidae. It is endemic to the Philippines. Its natural habitat is tropical moist lowland forests. It was formerly considered as a subspecies of the uniform swiftlet. Despite some fears around conservation, the species remains a Least-concern species. Description and taxonomy Ebird describes this species as "Medium-sized brownish swiftlet with a weakly forked tail. Found only in the Philippine lowlands. Typically encountered alone or in loose groups over various open habitats, often soaring high. Fairly uniform brown plumage, lack of a pale rump, and size distinguish this species from most others in the area; Philippine Swiftlet is the most similar but is smaller, has a more square-tipped tail, and generally favors higher elevations (typically 700 meters and above)." Subspecies Two subspecies are recognised: * ''A. a. amelis'' ( Oberholser, 1906) – Philippines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erwin Stresemann
Erwin Friedrich Theodor Stresemann (22 November 1889, in Dresden – 20 November 1972, in East Berlin) was a German naturalist and ornithologist. Stresemann was an ornithologist of extensive breadth who compiled one of the first and most comprehensive accounts of avian biology of its time as part of the ''Handbuch der Zoologie'' (Handbook of Zoology). In the process of his studies on birds, he also produced one of the most extensive historical accounts on the development of the science of ornithology. He influenced numerous ornithologists around him and oversaw the development of ornithology in Germany as editor of the ''Journal für Ornithologie''. He also took an interest in poetry, philosophy and linguistics. He published a monograph on the Paulohi language based on studies made during his ornithological expedition to the Indonesian island. Early life Stresemann was born in Dresden to Richard, an apothecary and Marie. His grandfather Theodor owned the ''Zum Roten Adler'' pharma ...

Birds Described In 1906
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 further ...

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] |
Aerodramus
''Aerodramus'' is a genus of small, dark, cave-nesting birds in the swiftlet, Collocaliini tribe (biology), tribe of the Swift (bird), swift family. Its members are confined to tropical and subtropical regions in southern Asia, Oceania and northeastern Australia. Many of its members were formerly classified in ''Collocalia'', but were first placed in a separate genus by American ornithology, ornithologist Harry Church Oberholser in 1906. This is a taxonomically difficult group of very similar species. Animal echolocation, Echolocation, DNA sequencing and Parasite, parasitic louse, lice have all been used to establish relationships, but some problems, such as the placement of the Papuan swiftlet are not fully resolved. These swiftlets can pose major identification problems where several species occur. What distinguishes ''Aerodramus'' swiftlets from other swifts, and indeed almost all other birds, is their ability to use a simple but effective form of echolocation. This enables t ...

Least-concern Species
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- ...

Uniform Swiftlet
The uniform swiftlet (''Aerodramus vanikorensis''), also known as the Vanikoro swiftlet or lowland swiftlet, is a gregarious, medium-sized swiftlet with a shallowly forked tail. The colouring is dark grey-brown, darker on the upperparts with somewhat paler underparts, especially on chin and throat. This species is widespread from the Philippines through Wallacea, New Guinea and Melanesia. It forages for flying insects primarily in lowland forests and open areas. It nests in caves where it uses its sense of echolocation, rare in birds, to navigate. Taxonomy The uniform swift was formally described in 1832 by the French naturalists Jean Quoy and Joseph Gaimard from a specimen collected on the island of Vanikoro in the Solomon Islands. They coined the binomial name ''Hirundo vanikorensis''. This swiftlet is now placed in the genus ''Aerodramus'' that was introduced in 1906 by Harry C. Oberholser. Twelve subspecies are recognised: * ''A. v. aenigma'' (Riley, 1918) – north, cent ... [...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 ...

Balambangan Island
Balambangan Island () is an island in Kudat Division, Sabah, Malaysia. It is located off the northern tip of Borneo and is situated just about 3 kilometres west of Banggi Island. It is now part of the Tun Mustapha Marine Park. History Alexander Dalrymple, an officer of the East India Company (EIC), concluded an agreement with Sultan Bantilan Muizzud-Din on 12 September 1762 whereby the Sultanate of Sulu ceded the island of Balambangan to the company, and Dalrymple took possession of the island on 22 January 1763. The establishment of a factory on Balambangan was officially approved by a committee of the board of directors in 1768 and Dalrymple was offered the role of management of the new settlement. However, Dalrymple quarrelled with the directors, and his insistence on absolute management of Balambangan led to his dismissal in March 1771. Dalrymple was replaced by John Herbert who commanded the ''Britannia'' as it transported soldiers, goods, and supplies from India in ...

Swift (bird)
The Apodidae, or swifts, form a family of highly aerial birds. They are superficially similar to swallows, but are not closely related to any passerine species. Swifts are placed in the order Apodiformes along with hummingbirds. The treeswifts are closely related to the true swifts, but form a separate family, the Hemiprocnidae. Resemblances between swifts and swallows are due to convergent evolution, reflecting similar life styles based on catching insects in flight. The family name, Apodidae, is derived from the Greek ἄπους (''ápous''), meaning "footless", a reference to the small, weak legs of these most aerial of birds.Jobling (2010) pp. 50–51.Kaufman (2001) p. 329. The tradition of depicting swifts without feet continued into the Middle Ages, as seen in the heraldic martlet. Taxonomy Taxonomists have long classified swifts and treeswifts as relatives of the hummingbirds, a judgment corroborated by the discovery of the Jungornithidae (apparently swift-like hum ...
