Grey-rumped Swiftlet
The grey-rumped swiftlet (''Collocalia marginata'') or grey-rumped swiftlet, is a small bird in the swift family Apodidae. It is endemic to the Philippines where it is found on most islands except Mindanao. Its natural habitat is tropical moist lowland forests. It was previously considered a subspecies of the glossy swiftlet. Description The grey-rumped swiftlet is in length with a square tail. The back and upper surface of the wings are dull dark blue with a moderate green gloss. The is paler due to the white margins of feathers forming the . The throat and upper breast are grey with fine white scalloping merging into larger greyish chevrons over the lower breast and flanks, becoming white over the belly. There is sometimes a tuft of small feathers on the , the rear facing toe. This species lacks the white spots on the inner webs of the tail feathers that are present in some ''Collocalia'' species. Taxonomy The grey-rumped swiftlet was described by the Italian ornithologis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tommaso Salvadori
Count Adelardo Tommaso Salvadori Paleotti (30 September 1835 – 9 October 1923) was an Italian zoologist and ornithologist.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

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] |
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- ...

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 ...

Visayan Islands
The Visayas ( ), or the Visayan Islands ( Visayan: ''Kabisay-an'', ; Filipino: ''Kabisayaan'' ), are one of the three principal geographical divisions of the Philippines, along with Luzon and Mindanao.

Ernst Mayr
Ernst Walter Mayr ( ; ; 5 July 1904 – 3 February 2005) was a German-American evolutionary biologist. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morphologically sim ...

Collocalia
''Collocalia'' is a genus of Swift (bird), swifts, containing some of the smaller species termed "swiftlets". Formerly a catch-all genus for these, a number of its former members are now normally (though not by all authors) placed in ''Aerodramus''. The genus ''Collocalia'' was introduced by the English zoologist George Robert Gray in 1854. The name ''Collocalia'' combines the classical Greek words ''kolla'' meaning "glue" and ''kalia'' for "nest". The genus previously contained fewer species. Seven subspecies of the glossy swiftlet were promoted to species status based on a detailed analysis of the swiftlets in the genus ''Collocalia'' published in 2017. Species Extant The genus now contains the following 11 species: * Plume-toed swiftlet, ''Collocalia affinis'' (formerly treated as a subspecies of the glossy swiftlet) * Grey-rumped swiftlet, ''Collocalia marginata'' (formerly treated as a subspecies of the glossy swiftlet) * Ridgetop swiftlet, ''Collocalia isonota'' (for ...
