Baglafecht Weaver
The baglafecht weaver (''Ploceus baglafecht'') is a species of weaver bird from the family Ploceidae which is found in eastern and central Africa. There are several disjunct populations with distinguishable plumage patterns. Only some races display a discrete non-breeding plumage. Taxonomy and systematics The origin of the word baglafecht is something of a mystery and was coined by Georges-Louis Leclerc, Comte de Buffon, probably from a local name in an Abyssinian language. Subspecies The following races are currently recognised: * ''P. b. baglafecht'' - (Daudin, 1802): Found in the Ethiopian highlands and southern Eritrea * ''P. b. neumanni'' - (Bannerman, 1923): Found in eastern Nigeria, Cameroon and Central African Republic * ''P. b. eremobius'' - (Hartlaub & Emin, 1887): Found in north-eastern Democratic Republic of the Congo and south-western South Sudan * Emin's weaver (''P. b. emini'') - (Hartlaub, 1882): Found in south-eastern South Sudan, south-western Ethiopia and northe ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ploceidae
Ploceidae is a family of small passerine birds, many of which are called weavers, weaverbirds, weaver finches and bishops. These names come from the nests of intricately woven vegetation created by birds in this family. In most recent classifications, Ploceidae is a clade, which excludes some birds that have historically been placed in the family, such as some of the sparrows, but which includes the monotypic subfamily Amblyospizinae. The family is believed to have originated in the mid-Miocene. All birds of the Ploceidae are native to the Old World, most in Africa south of the Sahara, though a few live in tropical areas of Asia. A few species have been introduced outside their native range. Taxonomy and systematics The family Ploceidae was introduced (as Ploceïdes) by the Swedish zoologist Carl Jakob Sundevall in 1836. Phylogenetic studies have shown that the family is sister to a clade containing the families Viduidae and Estrildidae Their common ancestor lived in the middl ...

Georges-Louis Leclerc, Comte De Buffon
Georges-Louis Leclerc, Comte de Buffon (; 7 September 1707 – 16 April 1788) was a French naturalist, mathematician, cosmologist, and encyclopédiste. His works influenced the next two generations of naturalists, including two prominent French scientists Jean-Baptiste Lamarck and Georges Cuvier. Buffon published thirty-six quarto volumes of his ''Histoire Naturelle'' during his lifetime, with additional volumes based on his notes and further research being published in the two decades following his death. Ernst Mayr wrote that "Truly, Buffon was the father of all thought in natural history in the second half of the 18th century".Mayr, Ernst 1981. ''The Growth of Biological Thought''. Cambridge: Harvard. p 330 Credited with being one of the first naturalists to recognize ecological succession, he was later forced by the theology committee at the University of Paris to recant his theories about geological history and animal evolution because they contradicted the Biblical na ...

Bird Measurement
Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The measurements of the lengths of specific parts and the weights of birds varies between species, populations within species, between the sexes and depending on age and condition. In order for measurements to be useful, they need to be well defined so that measurements taken are consistent and comparable with those taken by others or at other points of time. Measurements can be useful to study growth, variation between geographically separated forms, identify differences between the sexes, age or otherwise characterize individuals birds. While certain measurements are regularly taken in the field to study living birds some others are applicable only to specimens in the museum or measurable only in a laboratory. The conventions used for measurement can vary widely between authors and works, making comparisons of sizes a matter that needs considerable care. Methods and considera ...

Lore (anatomy)
The lore (adj. loreal) is the region between the eyes and nostrils of birds, reptiles, and amphibians. Ornithology In ornithology, the lore is the region between the eye and bill on the side of a bird's head. This region is sometimes featherless, and the skin may be tinted, as in many species of the cormorant family. This area, which is directly in front of the eye, features a "loral stripe" in many bird species including the red-capped plover. Herpetology In amphibians and reptiles, lore pertains to the regions immediately adjacent to the eyes and between the eyes and nostrils. These are analogous to the lore on birds which corresponds to the region between the eye and the beak. In snakes and reptiles, a loreal scale also refers to the scales which lie between the eye and the nostril. In crotaline snakes (pit vipers), loreal pits are present on either side of the head.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishi ...

Bwindi Impenetrable National Park
The Bwindi Impenetrable National Park (BINP) is in southwestern Uganda. The park is part of the Bwindi Impenetrable Forest and is situated along the Democratic Republic of the Congo (DRC) border next to the Virunga National Park and on the edge of the Albertine Rift. Composed of of both montane and lowland forest, it is accessible only on foot. BINP is a United Nations Educational, Scientific and Cultural Organization-designated World Heritage Site. Species diversity is a feature of the park. It provides habitat for 120 species of mammals, 348 species of birds, 220 species of butterflies, 27 species of frogs, chameleons, geckos, and many endangered species. Floristically, the park is among the most diverse forests in East Africa, with more than 1,000 flowering plant species, including 163 species of trees and 104 species of ferns. The northern (low elevation) sector has many species of Guineo-Congolian flora, including two endangered species, the brown mahogany and ''Brazzeia lo ...

Ploceus
''Ploceus'' is a genus of birds in the weaver family, Ploceidae. They are native to the Indomalayan and Afrotropical realms. Taxonomy and systematics Phylogeny The genus ''Ploceus'' was introduced by the French naturalist Georges Cuvier in 1816. The type species was subsequently designated as the baya weaver. The genus name is from Ancient Greek πλοκευς ''plokeus'' meaning "weaver", and is derived from the Greek word πλεκω ''plekō'' "to entwine". Based on recent DNA-analysis, the genus ''Ploceus'' is almost certainly polyphyletic. If all species currently included in the genus would remain and the genus would be made monophyletic, it would have to encompass the entire subfamily Ploceinae. The Ploceinae can be divided into two groups. In the first group, the widowbirds and bishops (genus '' Euplectes'') are sister to a clade in which the genera ''Foudia'' and ''Quelea'' are closest relatives and which further includes the Asiatic species of ''Ploceus'', i.e. ...

Birds Of Central Africa
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 ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 evolved for swimming. Birds ...
