Yellow-fronted Tinkerbird
The yellow-fronted tinkerbird (''Pogoniulus chrysoconus'') is a small African barbet formerly known as yellow-fronted tinker barbet. It is sometimes considered conspecific with its southern counterpart, the red-fronted tinkerbird, ''Pogoniulus pusillus''. Barbets are near passerine birds with bristles around the base of the bill and a world-wide tropical distribution. Subspecies The subspecies vary with respect to size and colour tone of the plumage streaks. They include: * ''P. c. chrysoconus'' (Temminck, 1832) * ''P. c. extoni'' Layard, 1871 — southern Africa * ''P. c. xanthostictus'' (Blundell & Lovat, 1899) If ''P. c. extoni'' is restricted to the southernmost population occurring in southeastern Botswana, northern South Africa and Eswatini, the following two subspecies are also recognized: * ''P. c. rhodesiae'' Grant, 1915 — Angola, Zambia, northeastern Namibia, Botswana and Zimbabwe * ''P. c. dryas'' Clancey & Lawson, 1961 — eastern to northern Mozambique and northwar ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch aristocrat, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna japonica'' (1844–1850).

African Barbet
The African barbets are birds in the family Lybiidae. There are 43 species ranging from the type genus ''Lybius'' of forest interior to the tinkerbirds (''Pogoniulus'') of forest and scrubland. They are found throughout sub-Saharan Africa, with the exception of the far south-west of South Africa. The African terrestrial barbets, Trachyphoninae, range from the southern Sahara to South Africa. Members of one genus, ''Trachyphonus'', are the most open-country species of barbets. The subfamily Lybiinae contains the African arboreal barbets. There are 37 species of Lybiinae in 6 genera. Description and ecology Most African barbets are about long, plump-looking, with large heads, and their heavy bill is fringed with bristles; the tinkerbirds are smaller, ranging down to the red-rumped tinkerbird (''Pogoniulus atroflavus'') at and . They are mainly solitary birds, eating insects and fruit. Figs and numerous other species of fruiting tree and bush are visited. An individua ...

Red-fronted Tinkerbird
The red-fronted tinkerbird, (''Pogoniulus pusillus'') is a small African barbet. Barbets are near-passerine birds with bristles around the base of the bill. They have a world-wide tropical distribution. The red-fronted tinkerbird is a widespread and frequently common resident breeder in eastern South Africa, with a separate population from southern Sudan and Ethiopia south to central and eastern Tanzania. It is sometimes considered conspecific with its northern counterpart, the yellow-fronted tinkerbird, ''Pogoniulus chrysoconus''. The red-fronted tinkerbird is associated with juniper forest and scrub. It nests in a tree hole and lays two or three eggs. It eats berries and fruit, particularly mistletoe, but also takes insects as it forages in deep cover. The red-fronted tinkerbird is in length. It is a plump bird, with a short neck, large head, and short tail. The adult has black upper parts heavily streaked with yellow and white, and a golden wing patch. Its head has a st ...

Near Passerine
Near passerines and higher land-bird assemblage are terms of traditional, pre-cladistic taxonomy that have often been given to tree-dwelling birds or those most often believed to be related to the true passerines (order Passeriformes) owing to morphological and ecological similarities; the group corresponds to some extent with the Anomalogonatae of Alfred Henry Garrod. Biology All near passerines are land birds. However, molecular data does not support the traditional arrangement; it is now clear that "near passerines" and "higher landbirds" are not synonymous. Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising Passeriformes, Psittaciformes and Falconiformes. Orders Pterocliformes (sandgrouse), Columbiformes (pigeons), Cuculiformes (cuckoos), Caprimulgiformes (nightjars), and Apodiformes (swifts, hummingbirds) are no longer recognized as near passerines. The true near-passerine families are the Psittaciformes (parrots), the Falconiformes (fal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baikiaea Plurijuga
''Baikiaea plurijuga'', known as African teak, Mukusi, Rhodesian teak, Zambian teak or Zambesi redwood, is a species of Afrotropical tree from the legume family, the Fabaceae from southern Africa. Description ''Baikiaea plurijuga'' is a medium-sized deciduous tree with pinnate leaves each with 4-5 pairs of opposed leaflets. They show pink to deep mauve flowers have yellow stamens and are clustered in large axillary racemes; it flowers from November to April. The fruit are flattened, woody pods with a hooked tip which splits explosively sending the seeds out over some distance. Habitat ''Baikiaea plurijuga'' is confined to the Kalahari sands and the woodland which it dominates is known as Gusu woodland. This woodland grows on the deep, aeolian and fluvial Kalahari Sands which have virtually no clay or silt. These sands provide exceptional growing conditions for deep-rooting trees, but the deficiency in clay restricts tree growth to sites holding nutrients in the form of organi ...

Limpopo
Limpopo is the northernmost province of South Africa. It is named after the Limpopo River, which forms the province's western and northern borders. The capital and largest city in the province is Polokwane, while the provincial legislature is situated in Lebowakgomo. The province is made up of 3 former homelands of Lebowa, Gazankulu and Venda and the former parts of the Transvaal province. The Limpopo province was established as one of the new nine provinces after South Africa's first democratic election on the 27th of April 1994. The province's name was first "Northern Transvaal", later changed to "Northern Province" on the 28th of June 1995, together with two other provinces. The name was later changed again in 2002 to the Limpopo province. Limpopo is made up of 3 main ethnic groups namely; Pedi people, Tsonga and Venda people. Traditional leaders and chiefs still form a strong backbone of the province's political landscape. Established in terms of the Limpopo House of Tra ...

Midsummer
Midsummer is a celebration of the season of summer usually held at a date around the summer solstice. It has pagan pre-Christian roots in Europe. The undivided Christian Church designated June 24 as the feast day of the early Christian martyr St John the Baptist, and the observance of St John's Day begins the evening before, known as Saint John's Eve. These are commemorated by many Christian denominations, such as the Roman Catholic Church, Lutheran Churches, and Anglican Communion, as well as by freemasonry. In Sweden, the Midsummer is such an important festivity that there have been proposals to make the Midsummer's Eve the National Day of Sweden, instead of June 6. In Finland, Estonia, Latvia and Lithuania, Midsummer's festival is a public holiday. In Denmark and Norway, it may also be referred to as St. Hans Day. History Saint John's Day, the feast day of Saint John the Baptist, was established by the undivided Christian Church in the 4th century AD, in honour ...

Viscum
''Viscum'' is a genus of about 70–100 species of mistletoes, native to temperate and tropical regions of Europe, Africa, Asia and Australasia. Traditionally, the genus has been placed in its own family Viscaceae, but recent genetic research by the Angiosperm Phylogeny Group shows this family to be correctly placed within a larger circumscription of the sandalwood family, Santalaceae. Its name is the origin of the English word viscous, after the Latin ''viscum'', a sticky bird lime made from the plants' berries. They are woody, obligate hemiparasitic shrubs with branches long. Their hosts are woody shrubs and trees. The foliage is dichotomously or verticillately branching, with opposite pairs or whorls of green leaves which perform some photosynthesis (minimal in some species, notably ''V. nudum''), but with the plant drawing its mineral and water needs from the host tree. Different species of ''Viscum'' tend to use different host species; most species are able to use severa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
