Yellow-crowned Canary
The yellow-crowned canary (''Serinus flavivertex'') is a small passerine bird in the finch family. It is a resident breeder in eastern Africa. It was formerly considered conspecific with the Cape canary (''Serinus canicollis''). Its habitat is fynbos Fynbos (; , ) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. The area is predominantly coastal and mountainous, with a Mediterranean climate. The fynbos ..., grassland and gardens, preferably in highland areas. It builds a compact cup nest in a scrub. The yellow-crowned canary is 11–13 cm in length. The adult male has a green back with black edging to the wings and tail. The underparts, rump and tail sides are yellow, and the lower belly is white. The head is brighter in color than the Cape canary, yellow in colour, and the face is cinnamon. The juvenile has greenish-yellow underparts with heavy brown streaking. The yellow-crowne ...

William Thomas Blanford
William Thomas Blanford (7 October 183223 June 1905) was an England, English geologist and natural history, naturalist. He is best remembered as the editor of a major series on ''The Fauna of British India, Including Ceylon and Burma''. Biography Blanford was born in London to William Blanford and Elizabeth Simpson. His father owned a factory next to their house on Bouverie street, Whitefriars. He was educated in private schools in Brighton (until 1846) and Paris (1848). He joined his family business in carving and gilding and studied at the School of Design in Somerset House. Suffering from ill health, he spent two years in a business house at Civitavecchia owned by a friend of his father. His initial aim was to enter a mercantile career. On returning to England in 1851 he was induced to enter the newly established Royal School of Mines (now part of Imperial College London), which his younger brother Henry Francis Blanford, Henry F. Blanford (1834–1893), afterwards head of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three suborders: New Zealand wrens; Suboscines, primarily found in North and South America; and songbirds. Passerines originated in the ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, 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 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers. Many birds in other families are also commonly called "finches". These groups include the estrildid finches ( Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family ( Emberizidae) and the New World sparrow family ( Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Th ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism. Despite this lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Canary
The Cape canary (''Serinus canicollis'') is a small passerine bird in the finch family. It is a resident breeder in southern Africa and has been introduced to Mauritius and Réunion. Its habitat is fynbos, grassland and gardens, preferably in highland areas. It builds a compact cup nest in a scrub. The Cape canary is 11–13 cm in length. The adult male has a green back with black edging to the wing feathers wings and tail. The underparts, rump and tail sides are yellow, and the lower belly is white. The rear head and neck are grey, and the face is cinnamon. The female is similar, but with less grey on the head. The juvenile has greenish-yellow underparts with heavy brown streaking. This species is easily distinguished from the yellow-fronted canary by its lack of black face markings. The Cape canary is a common and gregarious seed-eater. Its call is ''tsit-it-it'', and the song is warbled goldfinch-like trills and whistles given in display flight or from a high perch. S ...

Habitat (ecology)
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior of a stem, a rotten log, ...

Fynbos
Fynbos (; , ) is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. The area is predominantly coastal and mountainous, with a Mediterranean climate. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% (8,500 fynbos) species of the Cape floral kingdom, where nearly 6,000 of them are endemic. The area continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it. Origin of the term The word '' fynbos'' is often taken literally to mean ''fine bush'', as in Afrikaans '' bos'' means '' bush'', whereas in this instance ''bush'' refers to the type of vegetation. Typical fynbos foliage is ericoid rather than ''fine''. The term in its pre-Afrikaans, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Goldfinch
The European goldfinch or simply the goldfinch (''Carduelis carduelis'') is a small passerine bird in the finch Family (biology), family that is native to the Palearctic zone in Europe, northern Africa, and western Asia. It has been introduced to other areas, including Australia, New Zealand, Uruguay and the United States. The breeding male has a red face with black markings around the eyes, and a black-and-white head. The back and flanks are buff or chestnut brown. The black wings have a broad yellow bar. The tail is black and the rump is white. Males and females are very similar, but females have a slightly smaller area of red on the face. The goldfinch is often depicted in Italian Renaissance paintings of the Madonna (art), Madonna and Child. Taxonomy The European goldfinch was one of the birds described and illustrated by Swiss naturalist Conrad Gessner in his ''Historiae animalium (Gessner), Historiae animalium'' of 1555.

Serinus
''Serinus'' is a genus of small birds in the finch family Fringillidae found in West Asia, Europe and Africa. The birds usually have some yellow in their plumage. The genus was introduced in 1816 by the German naturalist Carl Ludwig Koch. Its name is Neo-Latin for "canary-yellow". Many species were at one time assigned to the genus but it became clear from phylogenetic studies of mitochondrial and nuclear DNA sequences that the genus was polyphyletic. This was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into two monophyletic groups, a proposal that was accepted by the International Ornithologists' Union. The genus ''Serinus'' was restricted to the European serin and seven other species while a larger clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its desc ...
